Flowline Switch-Tek® LZ12 Vibration Point Liquid Level Switch, 3/4 in. NPT

Flowline's general purpose vibration single point liquid level switch provides high or low liquid level detection of dirty liquids with light or medium coating or scaling characteristics with a 1A relay output, examples include wastewater, diluted caustic soda and copper sulfate. The sensor automatically adjusts for coating build up, and if necessary, outputs a proactive maintenance alarm to request cleaning. The submersible polypropylene- Ryton® liquid level switch sensor can be universally mounted inside the tank or through the tank wall, and connected to a PLC or relay controller.

Features

• Automatic coating adjustment optimizes sensor performance, sensor measures and adjust to build up over time
• Submersible Ryton® sensor with polypropylene cable for corrosive liquids
• Plastic vibration sensor is well suited for use in corrosive liquids
• 60VA SPST relay selectable NO/NC via power supply wiring polarity
• Compatible with Smart Trak and Switch-Pak installation fittings
• Ideal for coating, scaling or crystalizing liquids
• Maintenance alarm proactively alerts user if sensor cleaning is required
