Bearing temperature sensor
MBT 3310
The MBT 3310 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 t
The sensor is tted with a 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
