THERMASGARD
Calibrateable screw-in temperature measuring transducers ⁄ immersion temperature sensors THERMASGARD
eight switchable measuring ranges, continuous output, enclosure made of impact-resistant plastic, enclosure cover with quick-locking
screws, and straight protective tube, ETM 1 including brass immersion sleeve, nickel-plated, optional with or without display for the
detection of temperatures in liquid or gaseous media. For aggressive media, stainless steel immersion sleeves (ETM 2) shall be used.
Applications of those temperature sensors are 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-calibrated. Adjustment ⁄ fine adjustment by the user is possi-
ble (zero point offset is adjustable).
