MBT 5252 Temperature Sensor

Brand: Danfoss

Heavy-duty temperature sensors for controlling cooling water, lubrication oil, hydraulic oil and refrigeration plants within general industry and marine applications. 

These temperature sensors are based on a standardized Pt 100 or Pt 1000 element, which gives a reliable and accurate measurement. 

In the low temperature version -50° to 200° C (-58° to 392° F) the measuring insert is based on a silicone cable, which makes the sensor very resistant towards vibrations. 

The MBT 5252 is equipped with a B-head as standard, but can also be delivered with B-mini Head on request. If needed, a transmitter (MBT 9110) can be ordered as an integrated part of the MBT 5252 sensor.
