Flow switch NJ NJV

Mechanical Flow Indicator / Switch for Water and Viscosity-Stable Oils

The NJ / NJV from Senseca is a robust mechanical flow indicator and switch designed for continuous monitoring of water (NJ) and viscosity-stable oils (NJV) in industrial applications. Operating on the spring-supported piston measuring principle, it features a magnetically coupled display with an optional reed switch for simultaneous visual flow indication and switching. The hermetically sealed display remains isolated from the process medium, ensuring reliable, maintenance-free performance even with dark or contaminated fluids.
