CPLS

The Capacitance Point Level Switch (CPLS) is a reliable device designed to detect levels of various materials, including liquids and powders, with features like a compact design and minimal maintenance. It operates using capacitance measurement and offers configurable output switching functions, with options for PNP or NPN outputs. The device can be paired with the Techtrol Switch Amplifier for controlling higher loads, and it includes user-friendly programming for setting empty/full levels and output functions.

Capacitance Point Level Switch ‐ ‘CPLS’

Specially designed, reliable level switch to detect level of


almost all materials, water and similar liquids, coolants,
lubricants, slurries, pastes, powders, grains and granules.

Salient Features
 Compact and robust design
 Trouble free operation with minimal maintenance
 Virtually capable to ignore build‐up on sensor
 Simple to teach empty and full level with two buttons.
 Easy to configure o/p switching function NO or NC
 Teach lock facility for safety operation

Construction and Working


The switch consists of an electrode with full PTFE insulation Schematic Diagram
and microprocessor based integral electronics housed in an
enclosure. It measures the capacitance formed due to
service material within its active area and provides PNP or
NPN switching output.
The CPLS can be also used alongwith Techtrol Switch
Amplifier (TSA), whose relay output can be used for higher
loads like pumps & solenoid valves.
