TBT1 Rotation Speed Sensor Application
TBT1 rotation speed sensor is a magnetoelectric rotation speed sensor, and it is installed to
the case or case cover of transmission gear, the tested rotary object is magnetic conductibility gear
which has two signaling hole with diameter 4 mm(depth 3 mm). It is composed of
permanent-magnet steel, electrical inductance coil, stainless shell, shield cable, connector, etc.
Output signal is similar to sine wave, adapting operation with other speed measuring control
equipment in the various transport facilities. The sensor can detect the rotational speed of
transmission gear and the speed of transport, applicable to various transport facilities.  

Features
Wide temperature accommodation

Installation\operation and malfunction disposal   Forbidden contact between terminals; otherwise the permanent-magnet would be
demagnetized greatly, even damaged.     Output wire distribution as per the definition strictly, and ensure it correct, without short
and open circuit;   Strong recommend the air gap between gear and the head of sensor is adjusted to 1.0
mm,after adjusting the air gap, tighten locknut;   When check the sensor, use the multimeter to measure DC resistance (connector pin C
and pin A), the resistance should comply to 850?±10%, which shows the sensor work normally.
