Heavy-duty temperature sensor for controlling cooling water, lubrication oil, hydraulic oil and refrigeration plants within general industry. This temperature sensor is based on a standardized Pt 100 element, which gives a reliable and accurate measurement. The changeable measuring insert is equipped with a silicone cable, which makes the sensor very resistant towards vibrations. The MBT 3252 is equipped with a B-head as standard. If needed, a transmitter (MBT 9110) can be ordered as an integrated part of the MBT 3252 sensor.
