Temperature sensor Type MBT 5550

With the MBT 5550 we have combined our temperature transmitter with a detachable thermowell MBT 120 enabling replacement of the transmitter while the application is in operation.

The MBT 5550 is designed for use in harsh environments where reliable, robust, and accurate equipment is required.

Features

• Designed for use in harsh marine & industrial environments where reliable, robust, and accurate equipment is required

• All metal enclosure parts made of stainless steel (AISI316)

• Output signals: 4 – 20 mA or Ratiometric 10 – 90%

• A wide selection of process and electrical connections are available

• Compact design

• Measuring range -15 to 200 °C

• Based on Pt 1000 sensor technology
