Description
Immersion temperature sensor
THERMASGARD® TF 54
THERMASGARD® TF 54 resistance thermometre or temperature sensor device with passive output, connecting head made of aluminium, and straight protective tube. The basic unit can be compined with accessory to provide four different device versions, e.g. with a separate stainless steel thermowell for robust applications.
The duct temperature measuring transducer serves to detect temperatures in liquid or gaseous media. It is used in pipes, heating engineering, storage systems, compact district heating stations, warm and cold water systems, oil and lubrication cycle systems, mechanical, apparatus and plant engineering and throughout the industrial sector.
