System description

1.1 Function and applications The Hygrophil HP 1100-10 is a probe designed to measure gas humidity in industrial processes. It is necessary to monitor and control the gas humidity in many processes in order to guarantee consistently high product quality and economic use of energy. The sensor basically works on the capacitance principle but without any chemical interaction or recalibration cycles. A condensation reaction is induced similar to that at dew point mirror. This monitoring process works continually with zero drift as the dew point is determined by measuring the temperature (Pt1000). The sensor boasts long-term stability and a high level of accuracy. The Hygrophil HP is designed for gas temperatures of up to 250°C. The Hygrophil HP 1100-10 process hygrometer is low-maintenance, can be used in industrial applications in continuous operation and is very suitable for process control.Please consult our sales staff. Example applications:

● Textile stenter dryers

● Ovens

● Hood dryers

● Ceramic dryers

● Smokers

● Food industry (FDA-approved)

● Roasters

● Gypsum plasterboard drying systems

● Rotary kilns

1.4 Principle of measurement The basic principle is a direct measurement of the temperature of dew point. A Peltier cooler is used to cool the sensor tip down to the point at which moisture condenses on the sensor tip. This condensation is picked up by capacitance, and the temperature is output as the dew point after a system-specific reading and correction process. In order to enable measurements at process temperatures up to 250 ° C, the measuring system is thermally connected to the heat sink outside the process room by heat pipes.

Safety precautions

Safety precautions

2.1 General information The products are made in compliance with the applicable regulations and leave the factory in perfect condition after having undergone thorough safety tests.

● The installation and maintenance of the products must be carried out by qualified staff.

● Make sure that the data and operating conditions specified by BARTEC BENKE are observed.

● Study the operating instructions before installing and starting up the product. If you have any questions about any particular points, please contact our customer service.

● Brief your operating and maintenance personnel thoroughly and provide them with all the essential information.

● The product's internal error messages are no replacement for safety installations in the larger system in which the product is integrated.

● It is imperative to comply with all the regulations governing the operation of your system.

● Damage caused by non-observance of these operating instructions voids the warranty! For further damages we do not accept liability.

2.2 Operating the Hygrophil HP sensor No special measures need to be taken if the installation instructions are followed for use in the process zone. The starting time of the product to settle will depend on the temperature of the process gas and the dew-point level and may be a few minutes. During this time, the moisture content, gas temperature and gas flow may change without affecting the output. The product will signal the end of the start process by indicating a change in the alarm and error contact status.

Attention: When operated outside the process environment with the filter removed, the measuring surface of the sensor can reach temperatures in excess of 100°C. Risk of burning! Do not bring the hot sensor measuring surface into contact with flammable materials or melting substances.

Do not use sharp-edged tools to clean the measuring surface, as this could damage the sensing equipment. Follow the cleaning instructions (section 6.2).

Safety precautions

13


2.3 Installation instructions

● Install the product as necessary in order to meet the ambient temperature specifications. High ambient temperatures at the heat sink push the lower limit of the humidity measuring range upwards at high process temperatures. (see diagram "Measuring range" in chapter 1.3)

● Mount the device so that only the tube with the measuring tip protrudes into the process chamber. The sensor must not be in the process room as a whole.

● As far as possible, install the units in a location which is free of vibrations.

● Choose the installation location so that the measuring tip is not hit by dripping or splashing water.

● If the dew point temperature in the process room is above 60 ° C, first put the sensor into operation and then insert the measuring tip into the process area. This avoids excessive condensation and associated measurement errors.

● Install a power supply line for the unit with an adequate cable cross section.

● Avoid sources of electromagnetic interference, e.g. motors, transformers, etc.

● If possible, ensure that there is a spatial separation between the moisture transmitter and potential sources of interference such as contactor switches or frequency converters.

● Please contact our staff if you have any questions about the electrics and the place of installation. Warranty claims will not be honoured in case of defects caused by your own actions!

2.4 Electrical installation instructions

● Before connecting the auxiliary power supply, make sure that the supply voltage is compatible with the operating voltage of the product.

● The wiring work must be carried out by qualified professionals.

● It is necessary to comply with the national regulations relating to wiring and with the wiring data in the technical specifications (cf. section 1.3). We recommend a power supply cable with flexible cores and core cross-sections of 0.75-1.5mm2 and a signal cable with core cross-sections of 0.25-0.75mm2. The outer diameter of the cables may be 5-10mm.

● All sensor and signal lines must be installed separately from control voltage and mains voltage lines (in separate cable ducts of their own).

● Shielded meassurement lines and signal lines provided by the customer should be grounded on one side of the product only.

Safety precautions

14


2.5 Operating instructions

● Voltage fluctuations are only permissible within the specified tolerances.

● After a power failure the Hygrophil HP will automatically start with the starting process.

● If there is reason to believe that the product cannot be safely operated, it must be taken out of operation immediately and measures put in place to prevent it from being put back into operation.

● Flammable gases: The sensor may not be used in explosive gases.

● Do not expose the sensor to aggressive gases or vapors which attack the materials used on the probe (cf. section 1.3).

● Dust and oil: Change the filter periodically depending on the degree of soiling (cf. s 2.8)

● The sensor is not suitable for permanent measurement of low dew point temperatures (<20 ° C). Make sure that the sensor is de-energized as soon as the dew point temperature in the process room falls below the dew point temperature of the environment. Continued operation under such conditions leads to condensation in the sensor unit and its destruction.

● Interruption of the power supply in the case of high humidity (DT> 60 ° C) can lead to condensation between the filter and the sensor surface at process temperatures below 160 ° C. The heating process after the return of the power supply may eliminate this condensation only incompletely and the sensor will give up to complete drying out too high humidity values.

Installation

15


Installation The installation of the moisture probe may vary from vertical to horizontal. A "hanging" assembly (tip up) affects the function, leads to damage at high process temperatures and is therefore not permitted! The cooling elements must be at least 75 mm from the surface at the place of installation.

3.1 Mounting

Mount the flange for receiving the probe at the measuring point.

Install the Hygrophil HP in the flange

The four M4 internal threads can be used for mounting their own flange constructions.

3.2 Installation and connection

● Undo the four screws on the housing cover, pry the cover open with a screwdriver to loosen it and then take it off. The terminal board is fitted in the housing cover and is connected with the electronic measuring equipment by a reverse polarity-protected ribbon cable. To disconnect the cable, press the pull-out safety on both sides of the plug in the cover and disconnect the plug.

Attention: Clamping work with the flat ribbon cable connected can lead to defects due to possible tensile forces.

● Feed the connection cable through the three entry points on the housing cover. Flexible cables with a maximum core cross section of 2.5 mm² an outer diameter about 5-10 mm can be used. Core cross-sections of 0.75-1.5mm2 for the power supply and 0.25-0.75mm2 for the signal lines are recommended.

Set up the electric connections for the power supply, analogue outputs and switching contacts according to the terminal marking on the circuit board. Tighten the screw terminals with a maximum tightening torque of 0.5 Nm.

5.6 Explanation of the test functions a-out 1 / a-out 2 If the input is activated, the just flowing (A-OUT1 / A-OUT 2) current at the respective output is accepted as

default. When the input is completed, the set current is issued on the respective output.

When leaving the menu "TEST FUNCTIONS", the control of the outputs is returned to the sensor.

error output(1) Switches the error output (S_OUT1) „OFF“ (contact open) or „ON“ (contact closed) according to the selection.

When leaving the menu "TEST FUNCTIONS", the control of the output is returned to the sensor.

warn output(2) Switches the warning output (S_OUT2) „OFF“ (contact open) or „ON“ (contact closed)

according to the selection. When leaving the menu "TEST FUNCTIONS", the

control of the output is returned to the sensor.

Servicing

6.1 Servicing and repair information

● Live parts are exposed when the housing cover is opened. Disconnect the product from the power supply before opening these parts, e.g. to do repairs or wiring work.

● Repairs which can only be carried out with the product open and the power supply connected may only be carried out by qualified professionals.

Attention: BARTEC BENKE shall not be liable for any damage caused by failing to adhere to the safety precautions and the operating instructions. This also applies to any consequential damage within the system as a whole.

6.2 Cleaning information No adverse effects on the measuring system can be expected if using the prescribed BARTEC BENKE filters for the sensor tip and adhering to the filter cleaning cycles as appropriate to the process. Dirt on the sensor can falsify the measurement results of the instrument. These must be removed with the following points in mind:

● Never clean the sensor measuring surface with sharp-edged mechanical aids. The sensor may be damaged!

● It is recommended to clean with a damp cloth and normal detergent. The sensor tip without filter (see 2.8) may also be completely immersed in the cleaning solution.Clean with an air compressor (max. 6 bar), maintaining a minimum distance of 20 cm from the sensor tip .

● Remove stubborn dirt with alcohol To do this, cumple the corner of a paper handkerchief together, moisten it with alcohol and wipe the sensor measuring surface with it.

● After cleaning, rinse the measuring surface with clear water and dry with a paper towel. The measurement surface should be free of residues.

● Do not touch the cleaned sensor surface with your fingers.

● Only ever clean the electronic housing with agents which do not attack its anodised coating.

6.3 Filter change If a filter change is necessary, proceed as follows:

Insert the filter key (accessory), unscrew and remove the filter insert by turning it anticlockwise.

Clean the sensor surface with a damp cloth. Please also observe the "Cleaning Instructions".

Insert the new filter carefully and screw it in by few turns

with hand.

Tighten lightly with the filter key the filter insert.

6.4 Check with test cap To check the sensor function, the cap, which also serves as a transport protection, contains a sponge that is dry and compressed when delivered. If this is moistened and the cap attached to the sensor, a saturated climate forms in the cap. The dew point temperature measured by the sensor then corresponds to the process temperature measured by the temperature sensor, and this in turn corresponds to the ambient temperature of the cap.

6.4.1 Filling the test cap Fill the test cap with clean tap water until it comes out of the vent hole. When filling for the first time, the sponge first has to swell up and can only absorb a little water at first. Continue to fill until the sponge has a thickness of about 2cm. Pour off excess water.

6.4.2 Test procedure Slowly insert the watered test cap onto the sensor for approx. 4-5cm. For horizontal sensor installation, align the cap with the vent hole at the top before fitting.

Attention: Through the air displaced during insertion can splash out of the vent hole of the cap water!

Wait at least 15 minutes for all balancing procedures to complete. With very different water and ambient temperatures, a longer waiting time may be required. If the sensor is intact, the process and dew point temperatures must now match ± 2 ° C.

Finally, remove the test cap and store it standing up to dry with the opening facing upwards.
