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
