LVC-152-R Economical Capacitance Level Switches Selectable NO or NC
Economical Capacitance Level Switch
Supported Applications
The Omega LVC-152 series consists of economical capacitance level switches designed for the reliable detection of conductive, light to medium coating liquids. The unique coating circuit rejects negative effects from coating or scaling build-up. These submersible sensors are constructed entirely of plastic with Polypropylene (PP) materials, making them suitable for corrosive environments in tanks and sumps.
According to the application matrix, the LVC-152 series is compatible with:
• Foam
• Bubbles
• Conductive liquids
• Translucent or opaque media
• Clean and turbulent conditions
• Metallic and non-metallic tanks
The series is not indicated for non-conductive, dirty, heavy coating applications, or hazardous locations.
Operating Conditions & Performance
The LVC-152 operates within a process temperature range of -40 to 90°C (-40 to 194°F). The sensor and cable are rated NEMA 6X (IP68) for submersible operation. Pressure capability is specified as 150 psi @ 25°C (76°F), derated at 1.667 psi per °C above 25°C (76°F).
Performance specifications include an accuracy of ±1 mm (0.04") in water and repeatability of ±0.5 mm (0.02") in water. The device requires a power supply of 12 to 36 Vdc.
Installation Constraints
A critical installation requirement is that the sensor must not be installed within 15.24 cm (6") of any metal object.
Configuration Options
The LVC-152 series features a selectable output state, configurable as Normally Open (NO) or Normally Closed (NC). The standard configuration includes an SPST relay contact and comes complete with a 3 m (10') cable. Extended cable lengths are available for special ordering: 7.62 m (25') by adding the suffix '-25' to the model number, or 15.24 m (50') by adding the suffix '-50'.
Key construction and connection details include:
• Housing Material: Polypropylene
• Process Connection: ¾ NPT
• Overall Length: 12.7 cm (5.0")
• Insertion Length: 7 cm (2.6") from the bottom of threads to the tip of the probe
• Cable Specification: 4-wire, 22 gauge with ground and shield, PP jacket
The series holds CE and RoHS certifications.
Key Product Differences
The primary model in this series is the LVC-152-R, described as a capacitance switch 12.7 cm (5") long. The standard unit includes a 3 m (10') cable; variations are achieved by appending suffixes for extended lengths (-25 or -50) to order longer cables.
