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
