Level Sensor (HLS)
- Made of chemical-resistant materials to assure compatibility with most liquids.
- It may be adjusted to operate over a wide range of levels.
Overfill protection switch.
Theory of Operation
The secret to the TSP-HLS’s reliability is its float switch technology. A small magnetically-activated reed switch is located inside the body of the sensor. Tiny magnets are positioned inside a lightweight float which is free to move up and down along the shaft so that the magnets are below the reed switch. When the sensor is immersed in liquid, the float rises and the magnet activates the reed switch, signaling the console that the high limit has been reached.
The HLS sensor is installed in a 2" NPT fitting on the tank. The level at which it operates may be adjusted by loosening a fitting and moving the sensor’s shaft in or out of the tank as required.
