Conductive level sensors are the go-to solution when you need reliable detection and control of electrically conductive liquids in industrial processes. These intelligent devices, such as those from Carlo Gavazzi, are designed to sense the presence or absence of a conductive medium by completing an electrical circuit between electrodes. They are typically configurable via DIP switches, allowing you to adapt sensitivity and function to specific tank geometries and liquid types. The sensors work with probes of varying lengths and can support up to four electrodes, enabling control of up to four distinct level points—ideal for multi-stage pump control or high/low alarms. Their compact housing and adjustable sensitivity make them a versatile choice for demanding environments.

These sensors are predominantly installed in industrial control panels, water treatment facilities, and pumping stations. Common applications include wastewater management, chemical dosing systems, cooling tower sump control, and boiler feedwater monitoring. They are also found in food and beverage processing where conductive liquids like juices or cleaning solutions are handled. The ability to configure the sensor for different fail-safe modes and hysteresis levels makes them suitable for both simple on/off control and more complex multi-point monitoring in automated systems.

Within this category, you will find subcategories such as basic conductive level relays and complete sensor kits with probes. Key article codes often follow a pattern like "CLS-XXXX" or "GCL-XXXX", where the suffix indicates the number of electrodes (e.g., -2 for two electrodes, -4 for four) and the housing type (e.g., -M for modular, -B for basic). For example, a Carlo Gavazzi conductive level relay might be coded as "GCL-4M" for a four-electrode modular unit. These codes are standardized across the manufacturer's range, ensuring easy identification and replacement.

Partnering with Electric Automation Network means you get more than just a component. We offer real-time pricing, express worldwide shipping, and dedicated technical support from engineers who understand the nuances of conductive level sensing. Whether you need help selecting the right sensitivity setting or configuring a multi-probe system, our team is ready to assist. We also provide detailed technical documentation for each article, ensuring you have all the data needed for a seamless integration.
