TM 65
Calibrateable temperature measuring transducer THERMASGARD
®
TM 65 with eight
switchable measuring ranges, continuous linear output, enclosure made of impact-resistant
plastic and enclosure cover with quick-locking screws, straight protective tube, optional with or
without display. For the detection of temperatures in liquid or gaseous media. For aggressive
media stainless steel immersion sleeves shall be used.
Applications of the TM 65 are in piping systems, in heating technology, in storage tanks,
in district heating compact stations, in hot-water 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 measuring transducers are factory-calibrated.
Adjustment ⁄ fine adjustment by the user is possible (zero point offset is adjustable).
