1piece Fiber optic pressure sensor PT25QL Fiber Digital Sensor

What should we pay attention to when selecting sensors?
Parameters of main need to determine the shape and size, detection distance, working voltage, output mode (NPN/PNP) (normally open/closed), output form the main parameters, at the same time also need to ensure that the sensor wire form (direct line/connector type), cable length, frequency, environment temperature requirements, waterproof and dustproof requirements (IP level) parameters such as accurate. In addition, if there are special testing requirements, you need to choose a special type of sensor, inductive sensor for example, Meiji can provide high pressure resistance, high temperature resistance, high frequency, strong magnetic immunity, analog output, explosion-proof type, no attenuation type of a variety of special requirements of sensor products for customers to choose.

What problems should be paid attention to in the use of sensors?

First of all, the correct wiring and stable supply of rated voltage should be confirmed, and then the characteristics of the sensor should be combined when installing the sensor. For example: inductive sensor installation need to pay attention to interference problems, to ensure that the distance between adjacent sensors cannot be too close, in some cases, you can try to choose shielding sensor, anti-interference effect will be relatively good.

Position setting of detection body?

The sensing distance of the sensor may change slightly due to the change of ambient temperature, voltage and other ambient conditions.Therefore, in order to make the sensor work steadily, the maximum proximity position of the detection body should be less than the induction distance.When using standard detection, the actual induction distance should be set below 80% of the action distance.In addition, when the shape of the detection body is smaller than the standard detection body or the detection body other than iron is used, the induction distance is shortened, so the actual induction distance must be shortened accordingly.
