Fill or Drain Control System with RX Outlet Relay

Intelligent Microprocessor Control
LED Status Indicators
Rugged Valve with Fail-Safe Design
Sensors & Valves Made in USA


Automatic "liquid level control system" includes a pair of SXL liquid level sensors, a 120V outlet relay, a power supply and wiring kit. Simply install the high and low set point sensors, connect the power supply and relay as shown in the manual. Sensors install with 1/4" NPT threads or included o-ring and nut allowing installtion in curved or thin flat walled tanks. LSM mounting kit allows sensors to be installed from the top of a tank with adjustable positions. Outlet relay and sensors operate on low voltage 24Vdc and can switch up to 12A 120Vac loads such as pumps or valves.

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.

Fill Kit: The low-level sensor turns on the relay to operate until the high-level sensor is activated.

Drain Kit: The high-level sensor turns on the relay to operate until the low-level sensor is activated.

RX Outlet Relay

Relay outlet is operated by the 24Vdc power supply from the level sensors and can switch up to 12 amps at 120 Vac. Customer must provide low-voltage 2-wire cabling between sensors and relay outlet.



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.

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.
