Data Sheet

Temperature sensor

Type MBT 5270

Compact temperature sensor for harsh marine applications.

The flexible temperature sensor MBT 5270 can be used in many marine and industrial applications such as: Air Compressors, Mobile Hydraulics and Marine EGR systems. In other words applications where robustness, size and performance are essentials.

The sensor can be equipped with different sensing elements (RTD and NTC).

Features:

• OEM Temperature Sensor program

• Various sensor elements available (RTD and NTC)

• Robust, high protection against moisture

• Fixed measuring insert

• Stainless steel

• Very low response times

• Temperature range up to 300 °C

• Available with cable and plug
