Optical Level Switches
Optical Level Switches from KOBOLD provide precise, reliable, non-contact level detection. They operate by sensing the difference in the refraction index between various media. When the liquid is not in contact with the sensor, all transmitted light is reflected back to the receiver. When the liquid contacts the sensor, part of the transmitted light is reflected back to the receiver and part is emitted into the liquid. The receiver senses this difference in signal loss and switches accordingly.
KOBOLD's optical level switches are highly sensitive and can detect small level changes, providing accurate and consistent performance. They are easy to install and integrate into existing control systems, offering real-time monitoring and control capabilities.
