CAMLogic Float Level Switch CLR20 Series

Introduction – CAMLogic Float Level Switch CLR20 Series

The CAMLogic Float Level Switch CLR20 Series is a high-performance stainless-steel instrument designed for precise liquid level detection in industrial environments. Utilizing a magnetic reed contact system enclosed in a fully sealed housing, it offers reliable monitoring of one or more liquid thresholds without requiring any external power supply.

Built from AISI 316 stainless steel, the CLR20 is exceptionally resistant to corrosion, making it suitable for both industrial and food-grade applications. Its friction-free operation ensures long-term durability and stable performance, even in demanding conditions such as foaming or viscous fluids.

The switch can be installed in vertical or horizontal orientations (curved version), offering maximum flexibility for integration in tanks, reservoirs, and process vessels. Its modular design allows for the detection of up to three distinct level thresholds, adapting to a wide range of applications across sectors.

Compact, rugged, and maintenance-free, the CAMLogic Float Level Switch CLR20 Series provides dependable level control performance trusted by engineers and plant operators worldwide, with Dubai Sensor serving as an authorized distributor for the UAE and MENA region.

Installation, Commissioning & Maintenance

The CAMLogic CLR20 Series is engineered for simple, tool-free installation. Mount the unit vertically with a tolerance of ± 30°, or laterally if using the curved version. Ensure the environment is free of strong external magnetic fields that might interfere with the reed switch.

To reverse the switch operation (NO ↔ NC), simply remove the retaining ring, invert the float, and reassemble. Periodic inspection is recommended to ensure the float stem remains free of deposits such as limescale. Electrical components are maintenance-free, and any repairs should be performed only by CAMLogic or authorized personnel.

FAQ – CAMLogic Float Level Switch CLR20 Series

Q1: What is the CAMLogic Float Level Switch CLR20 used for?
The CLR20 is designed for liquid level monitoring and control. It detects one or more level thresholds in tanks or vessels using a magnetic float and reed contact system.

Q2: Does the CLR20 require an external power supply?
No. The switch operates passively using a reed contact actuated by the magnetic float, so no external power source is needed.

Q3: Can the CLR20 be installed horizontally?
Yes. While the standard model is for vertical installation (±30° tolerance), the CLR20/C curved version is designed for lateral (horizontal) mounting.

Q4: How can I change the contact type from NO to NC?
Simply remove the retaining ring, invert the float, and reinstall it. This reverses the contact function between normally open (NO) and normally closed (NC).

Q5: What materials is the CLR20 made from?
The float is made from AISI 316Ti (EN 1.4571) stainless steel, and the body is made from AISI 316 (EN 1.4401), providing excellent corrosion resistance for industrial and food applications.

Q6: What are the operating temperature limits?
Standard version: –10 to +70 °C.
With silicone cable: –40 to +120 °C.

Q7: What is the maximum operating pressure?
The CLR20 Series can withstand up to 15 bar (217.5 psi).

Q8: How many level points can be monitored?
The CLR20 can monitor up to three liquid level thresholds, depending on configuration.

Q9: Is the CLR20 suitable for use with foaming or corrosive liquids?
Yes. Its stainless-steel construction and magnetic actuation make it suitable for foaming, corrosive, or viscous liquids.

Q10: What standards does the CLR20 comply with?
It meets RoHS (2011/65/EU), LVD (2014/35/EU), and EC 1935/2004 for food contact materials, and provides IP67 protection against dust and water ingress.

Q11: How much maintenance does the switch require?
Very little. Only periodic checks for deposits on the float stem are needed. The electrical parts are sealed and require no maintenance.

Q12: Where can I purchase the CAMLogic Float Level Switch CLR20?
The CLR20 Series is available through Dubai Sensor, the authorized distributor for the UAE and MENA region.
