Product Details

Product description


Metal photoelectric high pressure level switches FS-IR2003D are used to detect highly corrosive liquids. This has nothing to do with physical properties such as refractive index, color, density, dielectric constant and electrical conductivity.


The switch FS-IR2003D includes an infrared LED and a phototransistor. The light of the LED is directed to the prism. As long as the sensor tip of the prism is in the air, the light will be reflected inside the prism to the receiver. When the liquid in the container rises and wets approximately 2/3 of the glass tip, the infrared beam entering the liquid is interrupted and only a small part reaches the receiver.


The output of the sensor's transistor can be directly connected to the input of the control system, or an external relay can be energized. The output has a short-circuit protection function, and also has current, voltage and power limits.

Please note

1. In the long-term of using, the surface of the sensor is dirty due to liquid impurities, slight dirt will not affect the performance of the sensor. If dirt would cover all the surface of sensor, please inform us the particularity in advance, our technical department can optimize the treatment.

2. The sensor will be effected when exposed to direct sunlight. Please install it away from direct sunlight
