I. Overview of GUC2800 Intrinsically Safe Magnetostrictive Displacement Sensor for Mining Applications:
The GUC2800 mining displacement sensor operates on the principle of generating a strain pulse signal when two distinct magnetic fields intersect. The time required to detect this signal is then calculated to determine the precise position. One magnetic field originates from a permanent magnet within a magnetic ring, while the other stems from excitation pulses generated by electronic components in the sensor's electronics compartment. These excitation pulses propagate along a waveguide wire made of magnetostrictive material within the sensor at the speed of sound. When intersecting the permanent magnetic field within the magnetic ring, the mechanical vibration generated in the waveguide wire due to magnetostriction creates a strain pulse. This strain pulse is rapidly detected by the sensing circuitry in the electronics compartment. By multiplying the total time elapsed from the generation of the excitation pulse to the detection of the strain pulse by a fixed sound velocity, the positional change of the magnet can be precisely calculated. This process is continuous, enabling rapid measurement of new positions whenever the magnetic ring shifts. Since the output signal is a true absolute value—not proportional or requiring further amplification—signal drift or variation is eliminated. Unlike other sensors, periodic recalibration is unnecessary.
The GUC2800 mining displacement sensor is non-contact and wear-free. It offers high resolution, high precision, high stability, high reliability, fast response time, and long operational life. The sensor requires no recalibration or periodic maintenance.

III. Wiring Configuration for GUC2800 Intrinsically Safe Magnetostrictive Displacement Sensor for Mining Applications:
The sensor features five terminals: Power Positive (Red), Power Negative (White), Output Positive (Green), Ground (Blue), and Housing Ground (Shield Wire).
IV. Installation Method and Dimensions:
1. Inspect sensors and magnetic rings for integrity; route cables away from high-power equipment; prepare required tools.
2. Clean contact surfaces to ensure effective O-ring sealing; ground the housing reliably.
3. Maintain concentric alignment between magnetic rings and measuring rods without contact.
4. Wire strictly according to color codes or markings; never reverse power polarity; ensure shielding is grounded.
5. Conduct a standalone power-on test first. Move the magnetic ring to observe output changes. After confirming normal operation, connect to the control system to verify data.
