SXL Optical Liquid Level, Flow & Leak Sensor

Electronic optical liquid sensors are durable, have no moving parts and are easy to maintain. SXL sensors can detect fluid levels in tanks, flow in pipes, or leaks in drip pans when liquid touches the sensor tip. Wide voltage range and high current capacity makes the SXL sensor practical for TTL logic, industrial PLC or direct relay control applications. 1/4" NPT threading and removable wiring terminal block with pin-out cast into the hex head makes installation or replacement fast and simple. When the output is energized a red LED illuminates the sensor body giving a visual status indication. Available in 'wet-on' and 'dry-on' configurations, or PWM output for applications requiring error indication and failure monitoring. Other intelligent functions include "stable state" switching to detect splashing, output debounce and error indication from infrared flooding.

How it Works

When the sensor tip is dry, infrared light from an emitter is internally reflected back 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.

Output Options

SXL-1 and SXL-2 models connect directly to discrete inputs on Agrowtek's GC-Pro/XL control systems.
