Sick THTS Hygienic Resistance Thermometer

Sick THTS Hygienic Resistance Thermometer

Sick's THTS temperature sensor is a compact PT100 resistance thermometer suitable for hygienic applications within the food and beverage, cosmestics and pharamceutical industries.

The THTS is constructed of stainless steel and has a crevice free design of the wetted parts to ensure conformity to hygienic standards and is suitable for CIP and SIP processes.

A wide range of process connections which are welded gap-free to the connection housing are available as are multiple insertion lengths to allow for universal use.

In addition to a direct electrical connection to the PT100 element, an integrated transmitter is available with a 4mA to 20mA output signal.
