Details

The reliable monitoring of bearing temperatures demands a temperature sensor with special construction features. These special requirements concern the temperature transition point from the bearing housing to the temperature sensor. Due to the materials and the shape of the bearing housing it may be that the temperature sensor loses contact with the bearing surface because of thermal expansion. The resulting air gap invalidates the system output. The TF-M-PT100 VAL sensor is constructed in such way that the temperature sensor is pressed with a low initial force onto the surface so that an eventual deviation of the dimension due to heat expansion is axially compensated. A PT100 is used as the sensor. This is a resistor whose value changes proportionally to the temperature, producing a continuous signal. The unit consists of two modules which can be separated from each other. The "wet" part remains in the reservoir whereas the "dry" part can be inspected if necessary, thus eliminating the need to drain the reservoir for maintenance. The switch is fitted with an elastomer seal.
