Optoelectronic Level Switch - OLS-C01
Brand: WIKA Instruments Ltd.The model OLS-C01 optoelectronic level switch is used for monitoring the level of liquids. The optoelectronic sensor consists of an infrared LED and a light receptor.
The light from the LED is directed at a prism which forms the tip of the sensor. So long as the tip is not immersed in liquid, the light is reflected within the prism to the receiver.
Features- Compact design, no moving components.
- Mounting position as required.
- Accuracy ±2 mm.
- Visual indication of the switching status.
- Choice of electrical connections: PUR, PVC cable or circular connector M8.
