Why Choose the Lovato 11SN1 SN1 Level Detector Probe?
The Lovato Electric 11SN1 is an SN1 single-pole level electrode probe designed for detecting the level of conductive liquids in tanks and deep wells. With a nominal probe length of 100 mm, it provides a compact sensing solution for use with compatible Lovato level control systems in filling, emptying, pump-control and liquid-level monitoring applications.
The SN1 uses a stainless-steel electrode together with an insulating electrode holder and cable gland arrangement. When the conductive liquid reaches the electrode, the probe enables a compatible level control relay to detect the liquid condition and perform the required control function, such as operating a pump, valve or alarm.
Designed for straightforward field installation, the 11SN1 accepts a connecting conductor up to 2.5 mm² through a screw terminal. Lovato specifies a maximum operating temperature of +60 °C, while the cable gland accommodates cables with an external diameter between 2.5 and 6 mm to maintain effective sealing.

Reliable Conductive Liquid Level Detection
The Lovato 11SN1 operates as the sensing electrode within a compatible conductive-liquid level monitoring system. When the liquid reaches the electrode, electrical conductivity through the liquid can be detected by the associated level control relay. The controller can then use this change of state to manage equipment such as pumps, valves or alarm circuits according to the required filling or emptying function.
For deep-well installations, the probe can be suspended from its electrical cable to position the electrode at the required detection level. Lovato specifies an external connecting cable diameter of 2.5–6 mm for effective cable-gland sealing, with a maximum conductor cross-section of 2.5 mm².
