Capacitance Level Switches

Siemens capacitance level switches offer superior performance while reducing maintenance, downtime, and equipment replacement cost. Their robust aluminium or chemically resistive plastic enclosures last in harsh and abrasive environments, guaranteeing a long service life and low cost of ownership.

With a selection of options including PROFIBUS communications, digital displays, remote or local testing, and functional safety SIL2, improved safety and integration into your plant’s operations has never been easier.

The best-in-class inverse frequency shift approach to RF capacitance technology ensures accurate, reliable, and repeatable measurement, even in dusty, turbulent, and vaporous environments or in situations with product build up.

Because even a small level change creates a large and detectable change in frequency, the Siemens Pointek CLS series provides excellent resolution while consistently outperforming conventional devices.

Pointek CLS100

Pointek CLS100 is an RF inverse frequency shift capacitance point level switch for liquids and solids or liquid interface applications. Unique product design allows for sensitivity adjustment to tune out and ignore build up.

Benefits

• Inverse frequency provides high resolution and increased sensitivity
