Level Switches

​FCI’s broad line of level switches and interface switches detect, monitor and alarm on point levels of all liquids. Our level switches are designed for accurate, highly repeatable trip-point sensitivity in water, oils, chemicals in industrial plants and processes.  FCI’s electronic level switches have no moving parts to foul, clog or stick resulting exceptional reliability with no maintenance.  Industry’s largest choice of process connections ensures compatibility and ease of installation in pipes, tanks and vessels. They are rugged and robust to withstand outdoor installations and carry global agency approvals for application in explosive, hazardous environments.  Level switch output selections include heavy-duty DPDT relays or hermetically sealed relays. Both alarms are independently field configurable for liquid level, interface or temperature operation. Since all process media exhibit different heat transfer capabilities, highly sensitive FCI liquid level/interface controllers may be specifically calibrated to detect difficult interfaces between fluids -- including liquids, gases, slurries and foam regardless of their physical properties When your point level switch or interface switch application is best solved with an ultra-reliable, long service life and industrial-grade instrument, please look further at FCI’s selection below.
