Heavy-duty temperature sensors, type MBT 3250, 3252, 5250, and 5252
Discover 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. All three sensor types can be delivered with NTC/PTC elements on request.
•MBT 3250 temperature sensor (3D/AR)
•MBT 3252 temperature sensor (3D/AR)
•MBT 5250 temperature sensor (3D/AR)
•MBT 5252 temperature sensor (3D/AR)
In the low-temperature version (-50 to 200 °C), the measuring insert is based on a silicone cable, which makes the sensor very resistant to vibrations. The MBT 3250 and 5250 temperature sensors come with interchangeable measuring inserts equipped with EN 175301-803-A, Pg 9 as standard. The MBT 3252 and 5252 sensors are 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.
