Prospect DTZZIII series weighing controller is an elevator weighing device independently developed by our company to meet the weighing requirements of all passenger elevators, freight elevators, medical elevators and explosion-proof elevators. The weighing control system consists of two parts, one part is the control instrument part, and the other part is the weighing sensor part. The weighing sensor converts the weight signal into an electrical signal through the transmission cable to the control instrument part, which is processed by the control instrument part to complete the elevator weighing. When the weight of the elevator car changes, the control instrument can output multiple sets of relay contact signals and signals such as 0 ~ 10mA current, 0~10V, -10V ~ +10V voltage according to requirements. When overloading, the control instrument sends out sound and light alarm to provide accurate data for elevator weighing and starting. The load cell provides a variety of installation methods, which can be installed the bottom of the car, the head plate of the elevator rope, the shaft of the top wheel of the elevator, the beam of the top of the elevator, the pedal of the escalator, the traction wire rope and the shaft pin type installation, etc., and can be used in conjunction with the control instrument. The pressure sensor is made of chromium-nickel-molybdenum alloy, which conducts the load weight of the elevator car by sensing the deformation of the metal, and the overload capacity reaches 150-200%; the sensor detects the change of its displacement, so as to realize the load weighing of the elevator car.
