The LVSW-710/720 compact solid state liquid level switch is a great replacement for mechanical float-type liquid level devices. The switch employs proven ultrasonic technology and solid state integral electronics in a small package. The LVSW-710/720 provides reliable operation in virtually any liquid, regardless of viscosity. This eliminates problems of stickiness and failure rate due to finite mechanical life inherent in the mechanical float design. The combination of fully epoxy-sealed electronics and ultrasonic sensing technology will provide years of maintenance-free service

Rated 4 out of 5 by from Missing document info I couldn't find any documentation that describes the cable/wire information (gauge, insulation/jacket type, etc), so I wrote this review to provide that: The cable that was attached to mine is a Belden 9535, and Belden provides a nice spec sheet on their website.

Rated 5 out of 5 by from Great Sensor - Would Like to See Future Variations Sensor operating voltage is versatile (5-30VDC). My application uses 6VDC. Sensor is compact enough to make it work in tight areas. It is 1/2” NPT and 3” long. I would love to see the following variations in the future: 1) Make the wiring via a connector instead of cable coming out connector. This will allow easy removal. 2) If point 1 is not possible, make the cable longer, maybe 6-ft. 3) Make another sensor with longer length; may be 2-in longer. This will allow the shorter one to be used for level control, while the longer used for low level alarm.

Is the alarm point at the centerline of the body? Does the rotation of the sensor affect the alarm point? The manual is very unclear and has no indication of mounting orientation.

Asked by: Goon
Thanks for the inquire The entire gap would have to be filled to trigger an alarm condition. Additionally, the units can be mounted in any orientation.

Does the sensor need to be installed a certain distance from walls or obstacles to ensure proper functionality?

Asked by: Clapeyron
Thank you for your inquiry about the level switch. It does not have to install a specific distance from the side wall. As long s liquid can make contact, it will change stateas on the relay.
