Versatile Application Range for Challenging Conditions

The Pointek CLS300 offers a highly versatile solution for demanding applications requiring reliable level detection, even in harsh environments. Designed to withstand the rigors of heavy solids and abrasive materials, such as in the mining industry, the CLS300 is equipped with fully potted electronics to resist condensation, dust, and vibration. Its wetted parts, crafted from stainless steel with a PFA shield for high chemical resistance—or from ceramic and stainless steel in the high-temperature model—enhance its durability in extreme conditions. The CLS300’s “Active Shield” technology effectively minimizes interference from material buildup or long installation nozzles, ensuring accurate measurement across a range of media with varying dielectric constants.

Key Applications:

• Liquids, slurries, and bulk solids
• High-pressure and high-temperature environments
• Hazardous area installations
• Mining, milling, and other heavy-duty industries.

Active Shield Technology for Accurate Measurement

The CLS300 incorporates Siemens' "Active Shield" technology, which minimizes measurement interference from material buildup on the probe or from installation in long nozzles. This ensures reliable readings, even in applications prone to material buildup or with varying media types. The CLS300 detects materials with a dielectric constant of 1.5 or higher, responding to changes in capacitance to deliver accurate level readings across a wide range of media. This capability makes it ideal for industries where consistency and precision in measurement are critical, regardless of environmental challenges.
