Fill or Drain Control Sensor Set

Intelligent Microprocessor Control
LED Status Indicator
Industrial 5-24Vdc/1A Rugged Design
Made in USA


Automatic "liquid level control set" includes a pair of SXL liquid level sensors for high and low set point control of reservoirs, tanks etc. Connect the two sensors as shown in the diagram to any 5-24Vdc device (up to 1A) such as a relay or valve. Kit includes only the sensor set; a valve or relay must be provided.

Electronic optical liquid sensors are durable, have no moving parts and are easy to maintain. LED illuminates body to indicate when they are activated. Other intelligent functions include "stable state" switching to detect splashing, one-second output debounce and error indication. Highly reliable and accurate solid state electronic optical level control system.


How Optical Sensors Work


When the sensor tip is dry, infrared light from an emitter is internally reflected back to to a receiver. When the tip is wet, the majority of the light from the emitter escapes the tip into the fluid reducing the reflection to the receiver. A microcontroller drives the emitter, monitors the receiver and operates the output according to the model selected.

Simple Installation

Connect a DC power supply and relay/valve according to the diagrams. No controller is required!

Fill Kit: The low-level sensor turns on a pump or valve to operate until the high-level sensor is activated.

Drain Kit: The high-level sensor turns on a pump or valve to operate until the low-level sensor is activated.

LSM Mounting System

Convenient mounting kits install liquid level sensors on the end of any 1" PVC pipe for top-down installation in the top of a tank. Eliminate holes in the side of a tank and have adjustable depth plus the convenience of removing the sensor for easy cleaning and maintenance. Mounting flange kit with all stainless-steel hardware securely mounts the sensor pipe to the tank. Wing nuts allow quick access to the sensor and a set-screw in the flange allows quick and easy depth adjustments.
