Temperature sensor
Type MBT 5310
For monitoring of bearing temperatures in Wind turbines, engines and gearboxes applications
The MBT 5310 temperature sensor series is
specially designed for measuring the
temperature in bearings where there is a risk of
overheating.
To get a very short reaction time the measuring
element is placed in a way to secure a reaction
time of down to t0.5 = 6 sec. in water.
The sensor is tted with an adjustable spring
loaded protection tube which ensures metallic
contact between bearing and sensor at all
times.
Features
• For monitoring of bearing temperatures
where there is risk of overheating, in
applications such as:
◦ Wind Turbines
◦ Engines
◦ Gearboxes
• Based on Pt 100 / Pt 1000 technology for use
up to 200 °C
• Spring loaded to ensure good contact with
the bearing
