Application

The general purpose level switch package provides reliable, high or low liquid level detection with one relay or reed switch output and a compact junction box for integral wiring termination. Available in three level sensor technologies, select the sensor type based upon your application media. This polypropylene or PVDF liquid level switch package is broadly applied in bulk storage, sump and day tank level applications as a high level alarm or low level alarm.

Ultrasonic Level Sensor
Intrinsically safe - Broadly applied in chemicals, solvents, hydrocarbons and light weight oils

Vibration Level Sensor
General purpose - Applied in wastewater with light coating, crystalizing and foaming

Buoyancy Level Sensor
General purpose - Applied in clean water and non-coating chemicals

Features

Polypropylene or PVDF single-point level switch package for corrosive liquids

60VA relay or 15VA dry contact selectable NO or NC via wiring

Offered in 3 sensing technologies for broad application coverage: ultrasonic, vibration & buoyancy

Available in intrinsically safe and general purpose classifications
