Gjt 650mm Stone Mining Belt Metal Detector for Metal Tramps
The GJT-B series metal detector is an advanced solution in the field of metal detection. Designed with cutting-edge digital phase-shifting and detection technologies, it ensures high sensitivity and strong resistance to interference. This makes it ideal for use in various industries such as thermal power, cement, paper, mining, forestry, environmental protection, and construction materials. Its stable performance and efficient operation make it a reliable choice for conveyor belt systems.
Working Principle:
When a metal object enters the electromagnetic field of the sensor, it generates changing signals that the metal detector can detect. These signals are then processed electronically, triggering the actuation of an electromagnet or motor switch to remove the harmful metal from the conveyor belt. The device also features a timing function where the relay is delayed by 1 to 10 seconds after activation. The output control system has one pair of open contacts and another pair of closed contacts for safe and effective operation.
