Point Level Measurement

Your plant’s lifeline to safety, efficiency, and a headache-free day.

Modern point level technology plays a number of critical roles in your operations – either in partnership with other instrumentation or on its own. Backup alarming to material presence detection and/or point level monitoring, protection against running empty, or a cost-effective choice for material detection – Siemens' range of point level devices covers it all. Capacitance, ultrasonic, rotating and vibrating level switches are suitable for virtually all applications from bulk solids to liquids, and everything in between.

Our comprehensive portfolio features a range of technologies that provide extremely reliable and precise point level detection. The level switches offer superior performance while reducing maintenance, downtime, and equipment replacement cost. Their robust aluminum 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.


Foam, liquids, bulk solids applications, and interface can all be easily monitored by our switches.


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


Pointek CLS100 is the compact universal switch for constricted spaces. Pointek CLS200 is the standard universal switch with a wide range of communications and probe extensions and the Pointek CLS300 is for harsh, demanding applications with high temperatures and pressures.

Rotary Paddle

Rotary Paddle

One of the only paddles available with functional safety SIL2 options, SITRANS LPS200 rotary paddle switch is world-class for reliable and safe point level detection in bulk solids. Its rugged design combined with motor stop technology and rotation failure detection means that you can expect reliable and safe measurements every time. With a wide variety of paddle options available, there is a switch suitable for most applications.
