EGT RTD probes consist of a platinum resistance element that is encapsulated and circuited in a mineral insulated, metal sheath construction and terminated by means of a bare wire, quick connectors or terminal heads. This construction provides a rugged probe that is moisture, pressure, shock and vibration resistant and also is bendable up to the element area. Temperature, atmosphere, protection, response and service life should be considered. In general, the better the tolerance, the more expensive the thermometer. 316 SS is standard.
Smaller diameters are available on request.
For connection to instruments, various termination extensions are available. Select the circuit that is required to match your instrumentation. The designation of an RTD tolerance class is based on the percent allowable variation, in ohms, of the nominal resistance value at the reference temperature. However, for convenience, this ohmic tolerance is often expressed as an equivalent C temperature variation. Use only the process fitting or the thermowell flats for this purpose.
