Conductivity Level Sensor

About Conductivity Level Sensor

A low AC voltage is applied between the probe electrode and the tank wall (or reference electrode in case of insulated tank). When the liquid comes in contact with the electrode tip, a conductive path is established between the sense electrode and the tank wall / reference electrode. This current is sensed, amplified and made to operate a relay whose contacts in turn can be used for annunciation / control.

Tank level measurement for boiler water, reagent monitoring, highly corrosive liquids, Water, waste water, chemical, condensate, coolant, pump dry running protection, ETP, STP etc

Features:

• No moving parts, so free from maintenance.
• No special cable required for signal transmission, therefore economical to install.
• Long cable connections permissible between probe and evaluation unit.
• AC on probes to prevent electrolytic deterioration of electrodes.
• Low voltage on probe for operational safety.
• Variety of control functions and installation systems available.
• Variety of probes available for various process conditions.

Versatile Design & Installation Options

The sensors construction allows for flexible installation, accommodating vertical or horizontal placement with threaded, flange, or suspension mounting. Its compact size and lightweight profile make it blend seamlessly into various industrial setups, while the ability to select between rod or cable-type electrodes meets diverse operational needs.


Reliability in Harsh Environments

Engineered with SS316 stainless steel electrodes and a polypropylene insulator, this sensor resists corrosion and operates in ambient humidity up to 95% RH (non-condensing). The sensor performs consistently in temperatures from 0C to 60C and under a tank pressure of up to 2 bar, ensuring reliability even in demanding industrial applications.


User-Friendly & Low Maintenance

Installation is straightforward due to the sensors standardized dimensions, adaptable pole configurations (2 to 5 pole), and wiring options. With no built-in display, all output is managed via a relay (SPDT, max 5A at 230V AC) for simple integration with existing control systems. Its design minimizes upkeep, enhancing operational efficiency.
