The Honsberg VHZ-010GA006MB is a robust and reliable viscosity-compensated piston flow switch designed for monitoring oil and other viscous media. It operates on a float measuring principle, where a piston equipped with a magnet is lifted by the flowing medium against a spring force. When the flow rate reaches the pre-set switch point, the magnet actuates a reed switch located outside the flow area. Its key advantage is the viscosity compensation, which ensures accurate switching across a wide range of fluid temperatures and viscosities, making it ideal for lubrication circuits, hydraulic systems, and cooling applications where fluid properties can change during operation.
