Data Sheet

Temperature sensor Type MBT 5722

For monitoring bearing temperature in stern tubes

Designed specially for monitoring bearing temperature in stern tubes:

Flexible protection tube that makes it possible to reach bearings placed up to 20m from the terminal box.

Precision Pt 100 element secures fast and precise caption of the bearing temperature which makes it possible to prevent bearing damage.

Features

• Flexible sheath (bending radius down to R = 30 mm)

• Moveable compression tting

• Robust construction with resistance to shock and vibrations to IEC 60068-2-6

• Up to 200 °C media temperature with Pt 100 resistance element

• Short reaction time
