TQG19E speed sensor
Brief introduction
TQG19E is a kind of double-channel hall speed senor, the sensor is installed to the case or case cover of
transmission gear, the tested rotary object is magnetic conductibility gear whose module is equal to 2. It is
composed of permanent-magnet steel, magnetic energy convertor, amplifier shaping circuit, shell, shield cable,
connector, etc. Output signal is square wave, adapting operation with other speed measuring control
equipment in the various transport facilities. The sensor can detect the rotational speed of slewing gear and the
speed of transport and communication facilities, applicable to various transport facilities.
Features
Wide temperature accommodation
Wide speed measuring range
Strong shock resistance
Good tightness
Non-contact with tested gear, without abrasion
Convenient installation, simple and reliable

Installation\operation and malfunction disposal
We have already considered the terminal protection during the ex-work package of the sensor, please
take out the protecting cover when installation, and install the protecting cover when disusing the sensor;
Forbidden contact between terminals;
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 0.8mm, after
adjusting the air gap, tighten these two fixed screws;
Before the sensor not installed to speed measuring end cover, power connection, use ferromagnetic
slice to contact or leave the head of sensor, if there are high or low level changes, which means normal;
At normal operation, there are no change of sensor output level (high or low), which means the sensor
is damaged. Disposal method: change the sensor.
