TQG19G Speed Sensor

Application
TQG19G speed sensor is a double-channel Hall speed sensor, and it is installed to the case or case
cover of transmission gear, the tested rotary object is magnetic conductibility gear whose module is equal
to 2.75. It is composed of permanent-magnet steel, magnetic energy converter, 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 not
using 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.
