Overview
The DET series displacement sensor utilizes the principle of differential inductance to convert the mechanical quantity of linear movement into electrical quantity, thereby achieving automatic monitoring and control of displacement. It has the advantages of high temperature resistance, small size, high precision, stable performance, reliable operation, and long service life. It can operate continuously for one major overhaul cycle of the steam turbine without maintenance or replacement, and can meet various performance indicators of imported sensors, which can replace imported sensors. If you encounter any unresolved issues during use, please contact (phone: 028-87433019) and we will provide you with service as soon as possible.
Product Details
1Two lines engraved on the sensor core rodintervalIdentify the end face of the core rod insertion direction for the linear travel zoneThe "entrance" mark.
2 It is best to place the sensor vertically or horizontally to ensure that the iron core moves freely and does not come close to the magnetic conductor metal（≥20mm）， Do not approach strong magnetic fields or currents, and do not place the sensor locally within a closed conductor.
3 The stroke sensor of the hydraulic engine requiresOnly with a transmitter can it be used.As a userAttention should be paid to the following when configuring a transmitter:how manypoint：
①、The stability of the excitation power supply should be better than the basic error of the sensor1/4, the waveform of the stabilized power supply is a sine wave or square wave.
②、The excitation voltage frequency is generally taken as2.5KHZ。
③、It is best to use a linear rectification circuit or synchronous demodulation circuit composed of dual operational amplifiers for the detection circuit.
④、The load connected to the sensor should be greater than10KΩ。
4If the sensor operates in harsh environments, an anti-interference filter needs to be added to the transmitter power supply input line.
5When the sensor leaves the factoryStandard configuration is1meter longSix high-temperature resistant wires,The cable length can be extended according to demand,order goodsPlease explain.
