Supported Applications
The Omega LVSW-701 is a solid-state ultrasonic point level switch designed for top and side mounting applications to detect liquid levels. It serves as a direct replacement for mechanical float-type devices, utilizing proven ultrasonic technology with integral electronics. The series supports operation in virtually any liquid regardless of viscosity.
Operating Conditions & Performance
The LVSW-701 operates within a process temperature range of -29 to 71°C (-20 to 160°F) and handles pressures up to 1000 psig (6895 kPa). The device features fully epoxy-sealed electronics, eliminating issues associated with stickiness or finite mechanical life. Performance specifications include a repeatability of 2 mm (0.08") or better and a response delay of 0.5 sec.
Key Specifications
- Power Supply: 6 to 24 Vdc
- Output Signal: 1 A SPDT relay
- Leakage Current: Less than 50 uA
- Sensor Material: 316 LSS (Stainless Steel)
- Protection Features: Transient and reverse polarity protection
Configuration Options
The series is configured with a standard ¾" NPT process connection. The sensor construction utilizes 316 LSS wetted materials suitable for the specified pressure ratings.
Dimensions and Physical Configuration
- Overall Length: 4½" (114.3 mm)
- Sensor Width: 0.885" (22.5 mm)
- Sensor Length: 0.82" (20.8 mm)
- Gap Dimension: 0.312" (7.9 mm)
Electrical Connection Details
The unit includes a wiring configuration with specific color coding for function identification:
- V+ Input: Red wire (6 to 24 Vdc range per data sheet)
- V- Ground: Black wire
- N.C. Output: Brown wire
- C Common: White wire
- N.O. Output: Blue wire
- Chassis GND: Green wire
- Shield: Shielded cable
Key Product Differences
The LVSW-701 model is defined by its 316 LSS sensor material and 1 A SPDT relay output. The ordering structure allows for specification of the sensor material, relay type, and mounting configuration (e.g., ¾ NPT). This solid-state design distinguishes it from mechanical float switches by removing moving parts that are subject to wear or sticking in viscous media.

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?
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?
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

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.
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.
