Supported Applications
The Omega LV-510 Series Vertical Mount Compact Single Station Level Switch is designed for OEM applications in restricted or limited space. These single station vertical switches mount vertically at the top or bottom of a tank to monitor liquid levels.
• OEM installations requiring compact footprints
• Applications with smooth surface requirements for easy cleaning
Operating Conditions & Performance
The series operates within a process temperature range of -40 to 90°C (-40 to 194°F). It is rated for liquids with a minimum specific gravity of 0.8 and supports an ambient pressure rating of 25 psi. The unit features a sealed reed switch designed to resist vibration and shock.
• Accuracy: ±5 mm in water
• Repeatability: ±2 mm in water
• Hysteresis (Deadband): ±10 mm in water
Switch Ratings
The reed switch supports the following maximum resistive loads:
• 50 VA @ 120 Vac
• Max. Current: 0.4 A at 120 VAC, 0.2 A at 240 VAC (per table)
Safety and Notes
Contact protection is required for inductive loads to prevent arcing. The products are not designed for use in human applications.
Configuration Options
The LV-510 Series offers configurable wetted materials, output states, and physical dimensions tailored to specific chemical environments.
• Wetted Materials: Polypropylene (PP) or Polyvinylidene Fluoride (PVDF)
• Output Signal: Dry switch closure with selectable Normally Open (NO) or Normally Closed (NC) states
• Mechanical Configuration: The orientation can be changed from normally open to normally closed by removing the float and reversing it in the stem.
Physical Specifications
• Overall Length: 58 mm (2.3") or 53 mm (2.3") L depending on measurement point
• Diameter/Float Diameter: 25 mm (1.00")
• Process Connection: ⅛" NPT thread
• Cable: 0.6 m (2'), 2 wire, 22 gauge
Approvals and Certifications
The series includes General purpose and CE certifications.
Key Product Differences
The series distinguishes between two primary model numbers based on body material:
• Lv-510: Features a Polypropylene (PP) body with PVC cable material.
• Lv-511: Features a PVDF body with TFE cable material, offering compatibility with a wider variety of chemicals compared to the PP variant.
Both models share identical process connections (⅛" NPT), overall dimensions, and electrical specifications. The unit is shipped in Normally Open (NO) configuration by default.
