1. Prevent the debris from being deposited in the catheter and the sensor from coming into contact with corrosive or overheated media. 2. When measuring gas pressure, the pressure intake should be opened at the top of the process pipeline, and the sensor should also be installed in the upper part of the process pipeline, so that the accumulated liquid can be easily injected into the process pipeline. ...

1. There are 4 wires for the wiring sensor, among them, the red or brown wire is connected to the positive power supply, and the black wire is connected to the negative power supply; The green or blue wire is the dark output line, and the white or yellow wire is the bright output line, the user can choose one of them according to his needs, and the other is not used, but it should be insulated. Lines are not allowed ...

How laser sensors work In the industrial field, the most common laser sensor is the laser displacement sensor, also known as the laser distance sensor, which can accurately measure the position, displacement and other changes of the measured object without contact, and is mainly used to detect the displacement, thickness, vibration, distance of the object.
