THERMASGARD
Screw-in resistance thermometer ⁄ immersion temperature sensor THERMASGARD
with passive output and cable connection for installation in pipes, tanks, or vessels. The temperature
measuring point is fully integrated into the screw-in sensor and is therefore easy to install in piping.
The cable sensor is exchangeable. It is used to measure temperature in liquid or gaseous media, in
heating, ventilation and air conditioning systems.
