s195166230 – level control,cond,chge / disc
Carlo Gavazzi S195166230 is a 230 V AC conductive liquid level control relay with fixed sensitivity, selectable charging or discharging operation and an 8 A DPDT output for automatic maximum and minimum level control.
Why Choose the Carlo Gavazzi S195166230 Conductive Level Control Relay?
The Carlo Gavazzi S195166230 is a reliable conductive liquid level control relay designed for automatic monitoring and control of conductive liquids in tanks, reservoirs and industrial process systems. As part of the Carlo Gavazzi S195 series, it provides maximum and minimum level control for charging or discharging applications using compatible conductive level probes.
The S195166230 monitors the resistance between level electrodes to determine whether liquid is present at the required level. Charging or discharging operation can be selected using a switch on the front of the unit, allowing the same controller to be configured for filling or emptying applications. The S195 series uses fixed sensitivity, providing straightforward and dependable operation without the need for sensitivity adjustment.
Designed for a nominal 230 V AC supply, the S195166230 features an 8 A DPDT output relay and an 11-pin circular plug-in format. Green and red LED indicators provide clear visual indication of power and relay status, making the controller a practical solution for industrial pump, tank and process control systems.

Reliable Conductive Liquid Level Control
Conductive level controllers determine liquid level by measuring electrical conductivity between electrodes installed in a vessel. When a conductive liquid reaches or leaves the electrodes, the resulting change in resistance is detected by the controller and used to operate its output relay. This provides a simple and dependable method of controlling pumps, valves and other equipment without relying on moving mechanical floats.
The S195166230 can control two liquid levels and can be configured for either charging or discharging using the selector on the front of the unit. In a filling application, the controller can operate associated equipment to maintain liquid between defined minimum and maximum levels, while discharging mode can be used for automatic emptying or drainage control.
Typical Applications
- Automatic tank filling and emptying systems.
- Water and conductive liquid level monitoring.
- Pump start and stop control.
- Reservoir and storage tank management.
- Industrial process vessels.
- Water treatment and pumping installations.
- High and low liquid level control.
- Industrial machinery and process automation systems.
