Trafag TOS Optical Level Switch with the label Trafag Industrial Components extends the Trafag brand name to instruments manufactured by qualified partner companies.
Descriptions of Trafag TOS Optical Level Switch
Trafag Industrial Components complement the genuine Trafag product range to offer customers a complete portfolio from one single source. The optical sensor is located in a metallic body which includes a polysulfone prism inside of which there is inserted an infrared transceiver. As soon as the sensor is immersed in the liquid, the refraction index of the prism changes and a large part of the infrared beam is dispersed in the liquid, causing the output to change state.
Main features of Trafag TOS Optical Level Switch
- No moving parts
- Hermetic construction, sealed electronics
- Minimum degree of protection IP65
