Longitudinal Tearing Detector Working Principle
To tear detection device will longitudinal tearing detection device two
lead access KHP - Z mainframe, normal, sensors in the off state, output high
level. If there is material (coal) belt tearing apart, about 1200 g fall into
sensors, rubber guide point two wire short circuit, the keyboard output low
level, the tear light is lit, the host to perform relay release, realize the
tear protection, at the same time a language alarm signals.
Longitudinal Tearing Detector Debug
The
longitudinal tearing detection device installed in the bottom belt, two root
lead respectively to KHP - Z belt conveyor integrated protection device of the
host on the "ground" and "tear" interface, normal operation
of belt conveyor, the pressure according to tear with your hand lightly in the
sensor sensing surface, belt machine should be shut down, monitor host
"tear" indicator on the panel, at the same time, should be a loud
alarm "tear" language.
Longitudinal Tearing Detector Parameters
1
Interrupting capacity ：12V/0.2A。
2 Resistor ≤0.1Ω，After the vibration and impact ≤0.2Ω。
3 Operate value
Pressure-sensitive type tear sensor area 3000 cm2, 100 cm2 fell to 100 g material, sensor output 0 v.
4 Action value allowed error range
Pressure sensitive type tear sensor motion error of plus or minus 10% two output terminals should be connected, through to resistance＜0.2Ω
