Affordable, Advanced Sensor


The SAL18 series RF admittance point level switch, an advanced RF level switch, eliminates problems associated with product build-up on the sensor probe and makes setup quick and easy with pushbutton calibration.  Application control is enhanced with the independent adjustable time delay on material presence and material absence detections.


The SAL18 series RF admittance level switch is state-of-the-art in the technology and features a local LED indication, 20-250VAC/VDC universal power supply, pushbutton calibration, independent adjustable time delay for each material absence and material presence detection,  and can work with target materials with a dielectric constant down to as low as 1.5.  The SAL18 series is also very affordable compared to its competitors.
