CAMLogic CLC40 Series Conductive Level Indicator

Introduction – CAMLogic CLC40 Series Conductive Level Indicator

The CAMLogic CLC40 Series Conductive Level Indicator is designed for reliable and independent monitoring of two liquid level thresholds in conductive media. Using the principle of current flow between stainless-steel electrodes immersed in the liquid, the device activates one or two SPDT relay outputs for control or alarm functions.

Equipped with adjustable sensitivity and a programmable delay system, the CLC40 Series ensures accurate detection even in liquids with varying conductivity, minimizing false signals. Its reinforced polyamide housing and AISI 316 stainless steel electrodes provide excellent durability in industrial environments.

Installation is straightforward—requiring no special tools—and the device can be mounted in vertical or oblique positions, offering flexibility for various tank configurations. The CLC40 Series is widely used in water treatment, food processing, and industrial automation applications, including operations across the UAE and MENA regions, where precise liquid level control is critical.

Distributed officially by Dubai Sensor, this instrument combines Italian engineering precision with dependable on-site performance for demanding process conditions.

 CAMLogic CLC40 Series Conductive Level Indicator

Q1: What is the CAMLogic CLC40 used for?
A: The CLC40 is a conductive level indicator designed to detect and control one or two liquid level thresholds in tanks or vessels containing conductive liquids. It is ideal for applications such as overflow protection, pump control, and dry-run prevention.

Q2: How does the CLC40 detect liquid levels?
A: The device operates by measuring a small alternating current between stainless-steel electrodes immersed in the liquid. When the liquid reaches the electrode level, the current activates the corresponding relay output.

Q3: What types of liquids can be measured with the CLC40?
A: The CLC40 is suitable for conductive liquids with a minimum conductivity of 5 µS/cm. It is not recommended for greasy or oily liquids that form insulating layers on electrodes.

Q4: Can the sensitivity of the CLC40 be adjusted?
A: Yes. Sensitivity is adjustable via a trimmer located on the circuit board, allowing the device to adapt to liquids with lower conductivity.

Q5: What are the available power supply options?
A: The CLC40 operates with 115/230 VAC, 24/48 VAC, or 24 VDC power supplies, consuming just 1 watt.

Q6: Does the CLC40 offer delay settings to avoid false signals?
A: Yes. The built-in DIP switch allows users to set a signal delay of 0, 2, 6, or 10 seconds, minimizing false triggering due to turbulence or splashes.

Q7: How is the device installed?
A: The CLC40 can be mounted vertically or obliquely using its G 1½″ BSPP threaded connection. No special tools are required for installation.

Q8: What maintenance does the CLC40 require?
A: The sensor requires minimal maintenance. Periodically clean the electrodes to remove non-conductive deposits such as limestone or residue that could affect measurement accuracy.

Q9: What is the protection class of the CLC40?
A: The unit is rated IP65/IP67, ensuring protection against dust and water jets for indoor or outdoor use.

Q10: What standards and certifications does the CLC40 comply with?
