1 INSTALLATION1.1 Mechanical installation

Figure 1-1Recommended mounting position- Calibration direction and PLUG connector’s coupling direction: horizontal- Cable entry direction: from below- Process connection direction: horizontal- The UP arrow on flange should point upwards

GeneralFlange-mounted transmitter is installed directly on the sideof a tank. As a result the measurement conditions may bequite demanding. As far as possible, however, the locationof the transmitter should be such that the effects oftemperature variations will be as small as possible.Mechanical stresses, such as vibration, should also beavoided as far as possible.

The installation should be such that the operatingtemperature of the transmitter’s electronics will notexceed +80°C. For example, the tank must beinsulated if necessary (see Fig. 1-1). Sufficient spaceshould be provided around the transmitter to ensure freecirculation of air.

Table for Figure 1-2: Mounting accessories

1. Flange coupling DN802. Sealing plate DN80 1)

3. Nut

NOTE! The materials for the mountings should bechosen to withstand the ambient and process conditions.

1) The pickling of the pipework and tank should be takeninto account when choosing the sealing materials. Thematerials should resist any absorption of the picklingmaterial in the seal. E.g. Viton is recommended.

2.7 Set-up calibration, housing code T (withmanual adjuster)

The transmitter is factory-calibrated, with 1 sec. electricaldamping, for the range specified in the order. If range isnot specified, the transmitter will be calibrated for themaximum range.

Zero and Span adjusters are at the end of the housing,under protective rubber shield. TEST jacks are also underprotective rubber shield. Figure 2-5: housing T with PLUGconnector

Checkout procedure- See that the ripple on the supply voltage does notexceed 2.5 Vpp on 0-1000 Hz frequency range.- Check the nameplate for the factory-calibratedrange and zero suppression/elevation.- If necessay, readjust the zero.

3.2 Damping

If pulsation occurs in the measured pressure, it can bedamped with the damping trimmer position D under theprotective rubber shiled on the housing.

BLV820AV15.2.2013

Measuring rangeThe lower and upper range-values cannot differ from zero bymore than the maximum span.For example, range 4 transmitter whose measuring rangeis 0-4/100 kPa cannot be adjusted to measure 100...104kPa pressure, because maximum span is100 kPa.

The transmitter is factory-calibrated with minimumelectrical damping.To increase the damping, turn the trimmer clockwise.

Adjusting the damping does not affect the transmitter'sother calibration.

Damping adjustment :1. Turn the selector switch from RUN to position D2. Turn the regulating switch about ±20° so damping

adjustment is activated. Turn the regulating switch todesired value of damping. 0 s on the left side, 60 s inthe right side.

3. Turn the selector switch from position D to positionRUN.

Figure 3-4 Process value zero (PZ)

3.3 Calibration examples

First step is process value zero :1. Turn the selector switch from position RUN to position

PZ.2. PV ZERO is done when the damping trimmer is turned

once to both edges at least for 1 sec.3. Turn the selector switch from position PZ to position

RUN.

Procedure- Apply zero pressure.1. Turn the selector switch from position RUN to

position Z.2. Turn the regulating switch about ±20° so adjustment is

activated.3. Turn the regulating switch to a point where output is

closest to 4 mA. (adjustment range on fine adjustmentrange is ±0.75% of span and speed of adjustment is±2.5% of span / s)

4. Turn the selector switch from position Z to positionRUN.

- Apply full-span pressure.1. Turn the selector switch from position RUN to

position S.2. Turn the regulating switch about ±20° so adjustment is

activated.3. Turn the regulating switch to a point where output is

closest to 20 mA. (adjustment range on fine adjustmentrange is ±0.75% of span and speed of adjustment is±2.5% of span / s)

4. Turn the selector switch from position S to positionRUN.

- Apply zero pressure.- Repeat the adjustments to achieve the desired

SATRON VL pressure transmitter3.4 Liquid level measurement

Open tank

Liquid level measurement with pressure transmitter isbased on the measurement of the liquid’s static pressure.Static pressure does not depend on the shape or volume ofthe vessel. It can be calculated by multiplying the liquid’sdensity by the liquid level and acceleration of gravity:

p = ρ ρ ρ ρ ρ h g

where p = static pressure ρ = density h = height of liquid level g = acceleration of gravity

The pressure acting on the flange diaphragm is thusdirectly proportional to the height of the liquid level, and thetransmitter can be calibrated to measure liquid level.

The lower limit of the liquid level is normally above thetransmitter. This is taken into account through zerosuppression.h1 = difference between maximum and minimum height of measured level (2.5 m)

h2 = level’s minimum height from transmitter (1.5 m)

ρ =density of measured liquid (950 kg/m3)

g = acceleration of gravity (9.81 m/s2)

Span (p1) and zero suppression (p2)will then be as follows:

p1 = h1 ρ g = (2.5 m) (950 kg/m3) (9.81 m/s2) = 23.3 kPa

p2 = h2 ρ g = (1.5 m) (950 kg/m3) (9.81 m/s2) = 14.0 kPa

Measuring range = p2...(p2 + p1) = 14 kPa...37.3 kPa (140 mbar...373 mbar)

4. CONSTRUCTION ANDOPERATIONSensor ModuleThe piezoresistive sensor, which has a silicone oil fill, isisolated from the process with a diaphragm. Sensorpressure and temperature are measured with a 24-bit ADconverter. Linearity and temperature effects are digitallycorrected with an internal microprocessor connected to thesensor module.The sensor converts pressure to electrical signal. Theconversion is carried out through a Wheatstone bridgesupplied with direct current. The elastic displacementproduced in the bridge by the pressure causes bridgeunbalance which is measured as a DC voltage signal.

Compensation includes temperature compensation andlinearization. Each sensor is calibrated individuallythrough a resistance network connection. The temperatureinformation required by compensation is derived from atemperature measuring element located by theWheatstone bridge.Electronics ModuleThe electronics module converts the process pressuresignal from the sensor module to 4-20 mA output signal.The conversion can be made in linear, square root or

inverted mode, or it can be done through user-selectablepressure/output point pairs (2-16 points).

Transmitters provided with own display (code N) isequipped with operating keys that allow you to define thetransmitter’s all functions.The active functions required for signal shapingare in a customized IC which is divided into two sub-blocks: amplifier block and standard-signal shaping block.The standard-signal shaping block also includes zero,span and damping adjustments.

The interface stage includes failure protections toensure the transmitter's operation and nonfailure inpossible failure conditions. This stage also includes theTEST and cable connections
