SITRANS LC Continuous Level Measurement Radar Sensor

Product Information

The Siemens Level Measurement Guide provides comprehensive
information about level measurement technologies and their
applications. It highlights the importance of accurate and reliable
process instrumentation in the age of digitalization. Siemens
offers a complete range of level measurement devices backed by a
global support network.

Product Usage Instructions

Technology Selector

Siemens offers a range of level measurement technologies to meet
different application needs. Start by selecting the right
technology for your specific requirements to ensure low cost of
ownership and increased safety.

Non-Contacting Technology: Ultrasonic and Radar

Consider non-contacting technology, such as SITRANS LU
(ultrasonic) and SITRANS LR (radar), for most level applications.
These technologies require minimal maintenance, have no wear and
tear, and are easiest to commission and install.

Contacting Technology: Pressure, Guided Wave Radar,

Capacitance, Weighing

For high accuracy dosing/batching applications, use SIWAREX
(weighing) technology. For safety, assurance, and point level
detection, install devices like Pointek CLS, SITRANS LCS050,
SITRANS LVL, SITRANS LVS, or SITRANS LPS. SITRANS LG (guided wave
radar), SITRANS P (pressure), and SITRANS LC (capacitance) are
suitable for these applications.

Control Technology: Pre-Programmable Control Features

For applications that require more than strictly level
measurements, consider technologies like SITRANS LUT400,
MULTIRANGER, and SITRANS LT500. These technologies offer
pre-programmable control features, datalogging, extra
inputs/outputs, and full communication capabilities.

POINT LEVEL
A switch for every application with options for remote testing and extreme temperatures.

With options as simple or sophisticated as you need them to be, Siemens point level devices are your answer.
siemens.com/pointlevel

Whether you’re looking for backup, high- or lowlevel detection, interface, or dry run protection these switches will reduce your maintenance, downtime, and equipment replacement costs.
Remote testing? Not a problem. A range of Siemens point level instruments now feature convenient remote testing via single or two-channel remote test signal conditioners or your control system.
Product buildup? Rotary point level devices specialize in low bulk density applications, ensuring accurate readings even in dusty, turbulent, and vaporous environments. And because even a small level change creates a large and detectable change in frequency, Siemens capacitance switches provide excellent resolution while consistently demonstrating immunity to buildup.
Need functional safety in your application? Siemens offers the world’s first rotary paddle switch with SIL options in addition to a series of SIL instruments in all our point level lines.
Whatever your requirement, Siemens has a switch solution.
