6、 Test circuit:

The testing circuit for inductive sensors generally consists of an inductive sensor, a signal conditioning circuit, and a data acquisition circuit.

The signal conditioning circuit is mainly used to amplify, filter, and linearize the analog signal output by inductive sensors. It generally includes amplification circuits, filtering circuits, and linearization circuits. The amplification circuit can amplify the weak signal output by the inductive sensor to a suitable range for collection. The filtering circuit can remove noise and interference signals, and improve signal quality. Linearization circuits can convert the nonlinear characteristics of inductive sensors into linear characteristics, improving measurement accuracy.diode

The data acquisition circuit is used to convert the analog signal output by the signal conditioning circuit into a digital signal for digital signal processing and storage. The data acquisition circuit generally includes an analog-to-digital converter (ADC) and a microprocessor or microcontroller. ADC converts analog signals into digital signals, and microprocessors or microcontrollers are responsible for processing and storing the digital signals.diode

7、 Common fault phenomena and causes:

Inductive sensors may encounter some fault phenomena during use. Common fault phenomena and their causes are as follows:diode

(1) Abnormal or no output signal: It may be caused by damaged or poorly connected inductive sensors. Check if the connection of the inductive sensor is normal. If the connection is normal but there is still no output signal, it may be that the inductive sensor is damaged and needs to be replaced.diode
