These industrial thermometers are based on the dilatation principle. The liquid (generally alcohol) or mercury changes its volume displacing inside a marked prismatic capillary glass when temperature changes. The glass is protected inside a gold coloured anodised aluminium case. Bigger-sized cylindrical cases are available in brass and stainless steel for easier reading. The V-shaped thermometers are suitable for industrial applications, as well as marine and air-conditioning installations. Available ranges from -60°C up to 650°C according to DIN 16181/ DIN 16195.

The operation principle for thermo-resistances is based on the variation of electric resistance when temperature changes. The sensible element is a very thin string of platinum or nickel rolled on a cylindrical or flat isolated bearing. Which ohm value is defined according the international norm CEI 751, it is -100 V at 0ºC and 138,5 V at 100ºC. That's why this sensor is common known as Pt-100. This type of sensor is suitable for measuring temperature between -184ºC y + 689ºC. This sensor is protected by a stainless steel stem. The operation principle for thermo-couples is the thermoelectric effect, based on the generation of a tension or electromotive force because of the difference of dilatation coefficient between two different metals united in the same circuit. The most common thermocouples are the K type (Ni Cr - Ni Al), due to the wide measuring range (-200ºC to + 1250ºC), type J (Fe - Cu Ni) range 0-760ºC, suitable for corrosive environments. The S type (Pt 10 Rh-Pt) is recommended for temperatures up to 1700ºC.

This resistance (V) or tension (mV) parameters are driven to a digital indicator (IDT), where are traduced to ºC or ºF by means of a display. Frequently other output signals are used (0-20 mA, 4-20 mA, etc). For that purpose exists output signal converters, previously calibrated, usually mounted on the connection head.

To define a sensor the following information is required:

- Sensor type: Depending on temperature. Thermo-resistance (3 wire, 2 wire upon request) or thermocouple.

- Stem: Length and diameter depends on application. Supplied in stainless steel and others upon request, such as Monel 400, Hastelloy C-276, Inconel 600, Titanium, refractory steel AISI 310, etc., as well as PTFE or ceramic. Extension neck are available if required. Thermowells and extension necks are also available in order to avoid damages caused by erosion, corrosion, abrasion and high pressure processes.

- Head connections: Not specially required, temperature sensors can be supplied with a flexible silicone cable. When required temperature sensors can be supplied with a wide variety of connection heads: die cast aluminium case DIN-B or DIN-A, plastic case BBK , screwed top aluminium case NEMA IV, explosion proof cases, etc.

- Process connection: By means of a fix or adjustable thread, flange or bayonet type.

JR/JR20-TPT DESCRIPTION

The Junior-TPT and Junior20-TPT models are small format, 3¾ digit instruments designed for temperature

measurement with an input stage prepared for connection of Pt100 sensors with three wires. Software configuration allows selection of reading units (Celsius or Fahrenheit) and

resolution (degrees or tenths of degree). Optionally, it can be equiped with a 2-relay control output card (2RE). This option provides an output connector at the rear of the meter, status LED’s visible from the front and specific programming routines which are enabled

automatically once the card is installed.

Supplied in stainless steel AISI 316 (other materials upon request), thermowells are intended to protect thermometers and temperature sensors of high pressures, corrosive media, etc and also allows removing the instrument when the process is being carried out. Two main thermowell types are available: - The weld-in type is the economic type because of it contains weldings in the body. - The bar stock thermowell is specially indicated for high pressures. Special features such as stepped or tapered profile can be performed. Both types can be thread or flange connected in accordance to DIN standards or customer specifications. Special coatings PTFE and ceramic available for wetted parts. The diameter of the stem (or sensible element part) should be approx. 1 mm. less than the diameter of the thermowell hole in which the stem is to be fitted. Gaps greater than 0,5 mm. between hole and stem have negative effect on the heat transfer and lead to inaccuracies. In cases the gap cannot be avoided the stem may be filled with suitable thermic oil. When ordering, the following information should be observed: Instrument stem length and diameter (indicating if thread is included), connection thread, process hole diameter, material required and any special influencing variable (high pressure, etc).
