Capacitance Point Level Switch (CPLS) – Pune Techtrol

The Capacitance Point Level Switch is a highly reliable and specially designed level switch that can detect the level of a wide range of materials including liquids such as water, coolants, lubricants, slurries, and pastes, as well as powders, grains, and granules. Its versatility makes it an ideal solution for many different applications.

Capacitance Point Level Switch

The Capacitance Point Level Switch is designed with a fully insulated PTFE electrode and integral microprocessor-based electronics enclosed in a sturdy casing. It detects the level of materials, liquids, slurries, pastes, powders, grains, and granules by measuring the capacitance formed due to the service material within its active area.

The switch provides a PNP or NPN switching output and can also be used with the Techtrol Switch Amplifier (TSA) for higher loads such as pumps and solenoid valves.

Also, it is easy to configure the output switching function and features a teach lock facility for safe operation. Its compact and robust design ensures trouble-free operation with minimal maintenance, making it an excellent choice for level detection applications.

Key Features:

1. Robust and compact design
2. Low maintenance with reliable operation
3. Capable of ignoring build-up on the sensor
4. Easy programming for empty and full-level detection
5. Output switching function can be configured as NO or NC
6. Teach lock feature ensures safe operation.
