Screw-in resistance thermometer ⁄ immersion temperature sensor THERMASGARD
ESTF 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 so
is easy to install in piping. The cable sensor is exchangeable. It is used for temperature
detection in liquid or gaseous media, in heating, ventilation and air conditioning systems.
