FTWY-50 Displacement Sensor
1. Product Introduction:
The measuring element is a waveguide, and the sensitive component inside the waveguide is made of special magnetostrictive material. During the measurement process, the sensor's electronic chamber generates current pulses, which transmit inside the waveguide, thereby creating a circumferential magnetic field outside the waveguide. When this magnetic field interacts with the magnetic field generated by the movable magnetic ring sleeved on the waveguide for position changes, it causes magnetostriction in the waveguide, producing strain pulses. The position of the movable magnetic ring is determined based on these strain pulses.
2. Product Features:
The surface of the housing is anodized for corrosion resistance. It uses imported waveguide wire as the measuring unit, with DSP digital signal processing, high precision, no temperature drift, non-contact operation, and a service life of up to 20 years. The sliding rod ball head has automatic centering function for easy installation, and the maximum allowable movement speed is 10m/s.
3. Product Applications:
Widely used in position measurement fields such as civil engineering, rock engineering, machinery, water conservancy and hydropower.
4. Working Principle:
The FTWY-50 digital displacement sensor drives the samarium-cobalt alloy material to move inside the fixed Hall chip via the retractable measuring rod when the measured object moves. It outputs voltage signals using the Hall effect. The signal directly enters a 16-bit single-chip microcomputer for sampling, is converted into a digital signal, undergoes position nonlinear encoding, and finally outputs the displacement digital quantity directly via the RS485 standard.
5. Product Advantages:
The hallmark of this displacement sensor is that it directly outputs digital signals without the need for a reading instrument.
