Thermocouple Entry Gland for Pharmaceutical Autoclave (TCEG)

The Thermocouple Entry Gland (TCEG) is an essential tool for temperature validation of steam autoclaves.

The TCEG is a thermocouple feedthrough engineered to simplify the installation of validation thermocouples in a pharmaceutical autoclave, and has been specified by satisfied end users and autoclave manufacturers for many years. In two variants, the TCEG/1 seals up to 18 thermocouples and the TCEG/2 can seal up to 36 thermocouples.

18 side slots, each 4mm wide can accommodate up to 36 thermocouples in a variety of different wire formats. The side slots incorporate a curved base which follows the contour of the thermocouple jacket allowing them to nest and assist in the sealing process.

Please view our animation video to see an overview of how it works!

With additional Tee or 'Y' tubes, two TCEG's can be combined to seal up to 72 thermocouples. The gland is available with a wide range of tri-clover or screwed process connections, to allow mating with any autoclave port.

Thermal Detection can supply TCEG's individually or as part of a validation kit which can include all the validation items required such as thermocouples, tri-clover adaptors, spare sealants, clamps.

Please use the product enquiry form to tell us your requirements.
