The LVSW-701 Series solid state liquid level switch is a direct replacement for mechanical float-type liquid level devices. The switch employs proven ultrasonic technology and solid state integral electronics, and 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.

The LVSW-701 product data sheet shows the input power requirement as 6-24VDC. The LVSW-701 User Guide states the input power as 9-30VDC. What is the correct input power requirement?

Asked by: EL808
Thank you for your inquiry. Best to use a power source of 12 to 24 VDC to power the level switch and separate power is required for the dry contact 1 Amp relay.

Is this the best replacement for the discontinued LV751-DC radio frequency level detector?

Asked by: Certified
Thank you for your question? The only DC powered radio frequency level switch we have is the LVCN7212. The connection size for this sensor is ¾” and the maximum pressure this sensor can handle is 145PSI. Please review the specs for the LVCN7212 and ensure it will work for your application

what is the length of the cord.

Asked by: EdPa
Thank you for your inquiry about the level switch. The cable length is 12 inches and unfortunately, cannot be customized for longer lengths.

For the LVSW-701 Ultrasonic Liquid Level Switch I need the RoHS and the EMC Declaration of Conformity If the Low Voltage Directive (LVD) applies I nedd it also.

Asked by: glb4
Thank you for your inquiry about the level switch. Please direct your inquiry to our Customer Care Group and a representative can a copy of the Declaration of Conformity in a separate email. Also, the level switch is not RoHS Compliant as indicated on its data sheet.

I need a cable length longer than 12". Can you provide the cable specifications for the Omega LVSW-701 so we can search for a compatible cable to extend your cable length?

Asked by: EL808
Thank you for your inquiry. Unfortunately, there is no option to extend the cable length.
