LPT-6A Measurement of Photoelectric Characteristics of Photosensitive Sensors

Short Description:

Product Detail

Product Tags

Photosensitive sensor is a sensor that converts light signal into electrical signal, also known as photoelectric sensor. It can be used to detect non electric quantity that directly causes light intensity change, such as light intensity, illumination, radiation temperature measurement, gas composition analysis, etc.; it can also be used to detect other non electric quantity that can be converted into light quantity change, such as part diameter, surface roughness, displacement, velocity, acceleration, etc Body shape, working state recognition, etc. Photosensitive sensor has the characteristics of non-contact, fast response and reliable performance, so it is widely used in industrial automatic control and intelligent robot.


1. The illuminance of the light source is divided into three levels, each level can be adjusted continuously, and the maximum illuminance is not less than 1500lx
2. The range of voltmeter (measurement) is 200mV, and the resolution is 0.1mv;
The range is 2V and the resolution is 0.001V;
The measuring range is 20V and the resolution is 0.01V
3. Voltmeter (calibration) 0 ~ 200mV; resolution 0.1mv
