Horizontal Liquid Level Sensor
Horizontal Liquid Level Sensors are side-mounted at the specified level through a sealed hole in the side of a tank / container. The float rises and falls with the level, actuating reed switches according to set parameters. Signals are then sent to trigger an action with a system or process, making these components essential for accurate monitoring in applications such as flood control, industrial automation, robotic lubrication levels, agriculture, marine, HVAC and water level monitoring systems.
No power is consumed during standby status.
The sensor is available as a Normally Open or Normally Closed switch in Polypropylene, Nylon, Nitrile Butadine Rubber or stainless steel for harsh environments. They are easy to install and have a compact size, which is customizable, mix and match sensor housing and float material to suit the target liquid. The cable can be supplied as PVC or Teflon with the desired length and connector combination. Supplied with either a single or double switch point, the switch points to be determined to suit the application.
