Temperature sensor

Type MBT 3270

Compact industrial temperature sensor.

The flexible temperature sensor MBT 3270 can be used in many industrial applications such as: Air Compressors, Mobile Hydraulics and Exhaust gas return systems. In other words applications where robustness, size and performance are essentials.

The sensor can be equipped with different sensing elements (RTD, NTC and PTC) and is available with different electrical connections (Cable, Delphi Metri Pack, AMP junior power Timer, Deutch DT04).

Features:

• OEM Temperature Sensor program

• Various sensor elements available (RTD, NTC, PTC)

• Robust, high protection against moisture

• Fixed measuring insert

• Brass or stainless steel

• Very low response times

• Temperature range up to 300 °C

• Available with cable or integrated plug (Delphi Metri Pack, AMP junior power Timer, Deutsch DT04)
