LTU-101A-G-R Polyphenylene Sulfide, NO or NC Tuning For Level Switch
Tuning Fork Sensor | Polyphenylene Sulfide
Supported Applications
The Omega LTU-101A series is a tuning fork level sensor designed for liquid and slurry detection. The product overview identifies applications involving frequent liquid composition changes, specifically citing food, pharmaceutical, and wastewater environments. Factory calibration supports accuracy across various liquids, including lubricating oils and hydraulic fluids.
Operating Conditions & Performance
The series operates within a process temperature range of -40 to 80°C (-40 to 176°F). The pressure rating is specified as 150 psi (10 bar) @ 25°C (76°F), with derating applied at 1.667 psi (0.113 bar) per °C above 25°C (76°F). Performance metrics include an accuracy of ±1 mm (0.04") in water and repeatability of ±0.5 mm (0.02") in water.
The sensor features a NEMA 6 (IP68) enclosure rating. The overall dimensions are listed as 114 x 27 mm (4.5 x 1.05").
Media Compatibility
• Liquids
• Slurries
• Lubricating oils
• Hydraulic fluids
Configuration Options
The LTU-101A series utilizes a dual tuning fork mechanism vibrated at a high frequency. When the tuning fork is covered by liquid, a frequency shift activates the relay output.
