Non-intrusive level switch for tanks to
1in thick
A new, non-intrusive capacitance level switch detects liquids through non-metallic tanks up to 1" thick and mounts in a bracket on the exterior wall of the tank
A new, non-intrusive capacitance level switch detects liquids through non-metallic tanks up to 1" thick Offered in both general-purpose and intrinsically safe configurations, the level switch mounts in a bracket on the exterior wall of the tank and is an excellent choice for clean, conductive, non-coating or scaling-type liquids

A unique guard circuit rejects the negative effects of coating build-up on the probe of Flowline's new capacitance level switch by eliminating the coating signal path between the electrodes
The relay or FET output provides a reliable switch interface with remote devices such as PLCs, SCADA or alarms.
Selectable switch states are NO or NC.
Accuracy is ñ1 mm in water.
The level switch is supplied in a polysulfone enclosure rated NEMA 4X (IP68) with a 1/2" conduit connection, and includes CSA/NRTL (UL) and CE approvals.
The LP50 RF capacitance level switch detects the presence of liquids or air by measuring the conductive or dielectric values which are present in all materials.
An electrical capacitor is formed between the level switch and the outer tank wall.
As liquid rises or falls against the inner wall, the capacitance effect is greatly increased and the FET switch changes state.
Price for the LP50 Non-Intrusive Capacitance Level Switch starts at $195, with delivery from stock.
Add $40 for intrinsically safe models.
