Thermocouple Sensor with Solid Drilled Weld In Thermowell

Product ID: TWA101

The TWA101 is a temperature assembly combining a spring loaded thermocouple sensor and solid drilled weld in thermowell. This heavy duty construction is designed for use within applications involving high pressures and flow rates.

The TWA101 temperature sensor is available as a type E, type J, type K, type N or type T thermocouple in simplex, duplex or triplex configuration. The probe can specified with either an isolated, grounded or exposed sensor junction.

This thermocouple assembly is available with an aluminium, stainless steel or plastic connection head which has a M20 x 1.5 cable entry. The sensor can be terminated with a ceramic terminal block, 4 to 20 mA transmitter or supplied with tails. There is also an option to specify loop powered or battery powered indicator.

The TWA101 thermowell is available with either a parallel or tapered stem profile.

The solid drilled threaded thermowell is available in a wide selection of materials including 316 stainless steel, Alloy C276 (Hastelloy®), Alloy 400 (Monel®) and Alloy 600 (Inconel®).

In order to determine or prove the suitability and required dimensions of a thermowell based on the process conditions, we offer wake frequency calculations as per ASME PTC 19.3 TW-2016. In addition there are a number of other certification and testing services available including 3.1 material certificates, pressure testing and positive material identification (PMI).

The TWA101 thermocouple temperature sensor is available with optional ATEX Exia (intrinsically safe), ATEX Exd (flameproof) or IECEx Exd (flameproof) hazardous area approval for use within Zones 0, 1, 2, 20, 21 and 22.
