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.
