Pointek CLS100 is a compact 2-wire inverse frequency shift capacitance switch for level detection in constricted spaces, interfaces, solids, liquids, slurries and foam.

Pointek CLS100’s short insertion length of 100 mm (4") and versatility in various applications and in vessels or pipes makes it a good replacement for traditional capacitance sensors.

Its advanced tip-sensing technology provides accurate, repeatable switchpoint performance. The PPS (Polyphenylene sulfide) probe [optional PVDF (Polyvinylidene Fluoride)] is chemically resistant with an effective process operating temperature range from -30 to +100 °C (-22 to +212 °F) (7ML5501), and -10 to +100 °C (+14 to +212 °F) (7ML5610). The fully potted design ensures reliability in a vibrating environment such as agitated tanks up to 4 g. When used with a SensGuard protection cover, the CLS100 is protected from shearing, impact and abrasion in tough primary processes.

• Easy installation with verification by built-in LED
• Low maintenance with no moving parts
• Sensitivity adjustment
• Integrated cable or PBT enclosure versions available
• Intrinsically Safe, Dust Ignition Proof and General Purpose options available

Pointek CLS200 is a versatile inverse frequency shift capacitance level switch with optional rod/cable choices and configurable output, ideal for detection of liquids, solids, slurries, foam and interfaces. The digital version (with PROFIBUS PA) includes a display and provides additional diagnostic features.

The Pointek CLS200 is offered in standard and digital versions.

The standard version has 3 LED indicators with basic relay and solid-state switch alarms.

The digital version provides an integral LCD display for standalone use, and also provides PROFIBUS PA communication (Profile version 3.0, Class B) for connection to a network.

The power supply is galvanically isolated and accepts a wide range of voltages (12 to 250 V AC/DC for standard version and 12 to 30 V DC for digital version). The stainless steel and PPS (PVDF optional) materials used in the probe construction provide a temperature rating up to +125 °C (+257 °F) on the process wetted portion of the probe. The switch responds to any material with a dielectric constant of 1.5 or more by detecting a change in oscillating frequency, and it can be set to detect before contact or on contact with the probe.The CLS200 operates independently of the tank wall or pipe so it does not require an external reference electrode for level detection in a non-conductive vessel such as concrete or plastic.

• Potted construction protects signal circuit from shock, vibration, humidity and/or condensation
• High chemical resistance
• Level detection independent of tank or pipe earth reference
• Insensitive to product buildup due to high frequency oscillation
• High sensitivity allows installation in a wide range of liquids, solids or slurry applications
• Integral LCD display allows for easy setup of CLS200 when you can configure switching threshold, even under the most demanding process conditions (digital version only)
• Extended rod, cable and sanitary versions available
• Standard version: 3 LED indicators for adjustment control, output status and power
• Digital version: integral LCD display, and PROFIBUS PA communication

Pointek CLS300 is an inverse frequency shift capacitance level switch with optional rod/cable choices and configurable output. It is ideal for detecting liquids, solids, slurries, foam and interfaces in demanding conditions where high pressure and temperatures are present. The digital version (with PROFIBUS PA) includes a display and provides additional diagnostic features.

The Pointek CLS300 is offered in standard and digital versions.

The standard version has 3 LED indicators with basic relay or solid-state switch alarms.

The digital version provides an integral LCD display for standalone use, with PROFIBUS PA communication (Profile version 3.0, Class B) when required. Solid-state switch alarm is standard.

The robust design of CLS300 makes it specifically applicable for heavy solids applications where abrasive materials occur as in the mining industry.

The fully potted electronics are unaffected by condensation, dust or vibration.

Wetted parts are made of stainless steel or stainless steel with a PFA shield for high chemical resistance. Ceramic inserts are supplied with high temperature CLS300 devices. Materials with low or high dielectric constants can be accurately detected. The unique Active Shield suppresses interference from material buildup.

The unique modular design of the Pointek CLS300 provides a wide range of configurations, process connections, extensions and approvals to meet the temperature and pressure requirements of specific applications. The modular design makes ordering easier and reduces stocking requirements. A wide range of probe configurations are available, including rod and cable versions.
