MBT 3252 Temperature Sensor

Brand: Danfoss

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 standardised 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.
