Electronic liquid level switches

Rochester Sensors’ capacitance type liquid level switches are used in a wide variety of applications typically to protect critical equipment from low oil, fuel or coolant levels. Applications include engines, radiators and cooling packs, hydraulic oil tanks, coolant header tanks, compressors, e-transmissions, e-axles and EV battery thermal management systems.

Benefits of Our Electronic Liquid Level Switches

• Our capacitive switches are highly sensitive to changes in fluid level, enabling detection of even small variations. This high resolution allows the early detection of even the smallest of changes.
• Our liquid level switches are built to perform in the most demanding of conditions including areas of high temperature and vibration. This robustness gives you peace of mind in power generation, specialist vehicles, tanks/fuel systems and similar hard-use cases.
• With no moving parts, solid-state construction and a simple switching principle, our switches tend to require less maintenance over time.

Liquid level switches are capable of monitoring a wide range of liquid types (oil, coolant, fuel) and tank materials (metal or plastic) with minimal modification.
