Features

The TR2 sensor consists of a sensitive resistance thermometer cemented in a tantalum tip, which uses a threaded connection fitting and Gylon gasket and is screwed directly into the top of the head of the valve stem. The sensor wires are contained in a robust PTFE tube which, through the internal cavity of the valve stem, is connected to the terminal head. The advantage of the TR2 sensor is reduced response time as compared to the TR1 sensor. 

Dimensions and Design Data

• Internal pressure min / max    : -1 / + 6 bar   ( FV/87psi)

• Internal Temperature min / max    : -60 / 200  (-76°F to +392°F)

• Min / Max ambient temperature    : -25 / + 80°C  (-13°F to +176°F)  for instruments

The terminal head is made of cast aluminum (a stainless steel housing is also available), complete with terminals and suitable cable glands. The sensitive element is a Pt100 resistance thermometer (single, double, or triple) in Class A or B in accordance with EN 60751 and the measurement circuit may have 2, 3 or 4 wires. 

The TR2 thermometric sensors is a SIMPLE APPARATUS, in accordance with standard EN 50020 - 2003 (Electric apparatus for potentially explosive atmospheres - intrinsic safety protection "i"), paragraph 5.4.a. The TR2 thermometric sensor is a device that does not contain its own effective ignition source; it can therefore be used in environments with a danger of explosion and the presence of gas (Groups IIA, IIB and IIC).
