THERMASGARD ® ETM 4
Calibrateable screw-in temperature measuring transducers ⁄ immersion temperature sensor THERMASGARD
measuring ranges, with connecting head made of aluminium, continuous output, and separate stainless steel immersion sleeve for heavy-duty
applications. This immersion sensor is used for the detection of temperatures in liquid or gaseous media. Applications in piping systems, in
heating technology, in storage tanks, in district heating compact stations, in hot and coldwater systems, in oil and lubricant circulation systems,
in mechanical, apparatus and plant engineering as well as in the entire industrial sector. These temperature transmitters are factory-calib-
rated. Adjustment ⁄ fine adjustment by the user is possible (range and zero point are adjustable).
