Group is locking safety return circuit for the super setting weight of detection platform；
The purpose of 4 sensors is set: it is accurate to weight detecting, while 1 sensor being avoided error occur；
Material of the device to platform and its above carries out weight metering, mainly uses explosion-proof, water proof type weighing sensor
(principle of weighing sensor: elastomer (elastic element, sensitive beam) generates flexible deformation under external force, makes to be pasted onto him
The resistance strain gage (conversion element) on surface is also in company with being deformed, and after resistance strain gage deformation, its resistance value will change
(increasing or reducing), then this resistance variations is converted to electric signal (voltage or electric current) through corresponding measuring circuit, thus complete
At the process that external force is transformed to electric signal.
Can also conversion module be set: mainly the electric signal of sensor 4-20mA, being converted into switching value, makes its progress
Alarm or safety interlocking；
According to the weight set two values of setting platform and its unrestrained material, first is that alarming value, converts electrical signals into
Switching value (is exported) using contact open in usual, once there is a certain amount of spreading, the alarm system of device connection is opened, and is reminded
