CAMLogic CLR22 Series Float Level Switch

Introduction – CAMLogic CLR22 Series Float Level Switch

The CAMLogic CLR22 Series Float Level Switch is a compact and durable stainless-steel device designed for precise detection of liquid levels in industrial tanks and vessels. Its friction-free reed contact system, activated by a permanent magnet, ensures reliable operation over time with no mechanical wear. Built entirely of AISI 316 stainless steel, it provides superior resistance to corrosion and chemical attack, making it suitable for aggressive or hygienic process environments.

The CLR22 is especially suited for use where space is limited, thanks to its slim 30 mm float diameter and simple vertical mounting design. It can detect up to two level thresholds, allowing for efficient monitoring and control of filling or emptying operations. The switching configuration (NO or NC) can be easily inverted by simply flipping the float orientation — no recalibration or tools required.

Because the CLR22 operates without external power supply, it offers a safe and energy-efficient solution ideal for resistive load applications. The switch’s IP67 protection rating ensures full sealing against dust and water immersion, further enhancing its durability in demanding industrial settings.

Distributed by Dubai Sensor, the CAMLogic CLR22 combines European engineering precision with reliability suitable for UAE and MENA industrial automation sectors, meeting both performance and compliance requirements for modern process systems.

Installation, Commissioning & Maintenance

The CAMLogic CLR22 can be installed vertically (±30°) inside tanks or vessels. The float movement triggers reed contact switching, providing either a normally open or normally closed output depending on orientation. To change contact mode, remove the retaining ring, invert the float, and reinstall — no calibration or electrical adjustment is required.

During operation, ensure that no external magnetic fields interfere with the float mechanism. The switch requires no electrical maintenance; however, it is recommended to periodically check for scale or deposit buildup on the float rod to maintain smooth movement.

Why Choose CAMLogic CLR22 Series Float Level Switch

The CAMLogic CLR22 offers robust engineering, precision switching, and hygienic compatibility, making it an ideal solution for demanding liquid level detection. Its stainless-steel design withstands high pressure and harsh media, ensuring consistent operation even in corrosive or sanitary environments.

Backed by CAMLogic’s proven reliability and available through Dubai Sensor, the CLR22 represents a cost-effective, maintenance-free, and energy-independent level sensing solution for industrial automation and process safety applications in both global and regional markets.

FAQ – CAMLogic CLR22 Series Float Level Switch

Q1: What is the operating principle of the CAMLogic CLR22 Float Level Switch?
A: The CLR22 uses a magnetic float and a sealed reed contact. As the liquid level changes, the float moves along the stem, activating the reed switch to provide a NO or NC signal depending on the float orientation.

Q2: Does the CLR22 require an external power supply?
A: No. The device operates mechanically through magnetic actuation and requires no external power source. It is suitable for use with resistive loads only.

Q3: Can the switching mode (NO/NC) be changed?
A: Yes. The contact type can be inverted by removing the retaining ring, flipping the float upside down, and reinstalling it. This changes the output from normally open (NO) to normally closed (NC) or vice versa.

Q4: What materials are used in the construction of the CLR22?
A: Both the float and the housing are made of AISI 316 stainless steel, providing excellent corrosion resistance and compatibility with food-grade and chemical applications.

Q5: What are the maximum operating conditions?
A: The CLR22 is rated for a maximum pressure of 15 bar and a process temperature range of –10 °C to +70 °C (or up to +120 °C when equipped with a silicone cable).

Q6: Is the CLR22 suitable for use with foaming or viscous liquids?
A: Yes. The design allows reliable operation in foaming, viscous, or corrosive liquids, provided the minimum fluid density is 0.7 kg/dm³.

Q7: What is the protection rating of the CLR22?
A: The CLR22 carries an IP67 rating, making it fully dust-tight and protected against temporary immersion in water.

Q8: What certifications does the product comply with?
A: It complies with RoHS (2011/65/EU), Low Voltage Directive (2014/35/EU), and EC 1935/2004 for food-contact safety.

Q9: How often should maintenance be performed?
A: The switch requires minimal maintenance. Only periodic inspection for scale or residue buildup on the float rod is recommended to ensure smooth movement.

Q10: Where can the CAMLogic CLR22 be purchased?
A: The CLR22 Series is available through Dubai Sensor, the authorized distributor of CAMLogic products in the UAE and MENA region.
