Data Sheet

Temperature sensor Type MBT 3252

Heavy-duty industrial application temperature sensor.

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.

Features:

• Gaseous or liquid media, e.g. air, gas, vapour, water or oil

• Resistance or 4 – 20 mA signal

• Up to 200 °C media temperature

• Pt sensing element with silicone cable

• Can be used with 2 or 3 wire connections

• Interchangeable measuring insert

• Available with built-in transmitter

• Also available in a marine version as MBT 5252
