The 99 series ATEX and IECEx approved temperature assemblies incorporate a Thermocouple Head and a head mounted (hockey puck) temperature transmitter or a 6 post ceramic block. The sensor may include any thermowell (flanged or threaded).

The nipple union assembly is then fitted to an IME Model 1080 Thermocouple Head (Aluminum or SS316). Any model head mounted (hockey puck) temperature transmitter that has less than 3 watts power dissipation or a 6 post terminal block is mounted in the Thermocouple Head to complete the approved temperature assembly.
