Thermocouple Sensor with Fabricated Weld In Thermowell

Product ID: TWA501

The TWA501 is a temperature assembly combining a spring loaded RTD sensor and fabricated weld in thermowell. The RWA501 is designed for light to medium process conditions.

The TWA501 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 TWA501 features a parallel stem profile.

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

There are a number of optional certification and testing services available including 3.1 material certificates to ensure full traceability, pressure testing and positive material identification (PMI).

The TWA501 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.
