HONSBERG MR1K-015GM004-11
The HONSBERG MR1K-015GM004-11 is a robust and reliable piston-type flow switch designed for monitoring liquid media, particularly oils. Its key feature is the integrated viscosity compensation, which ensures a stable and repeatable switching point across a wide range of fluid viscosities (30-600 cSt), making it ideal for applications with fluctuating temperatures. The device operates using a spring-loaded piston which contains a magnet; as the flow increases, the piston is displaced and actuates an external, non-contact reed switch. This simple and durable mechanical design allows for installation in any orientation and provides high pressure resistance, making it suitable for demanding industrial environments such as hydraulic systems, lubrication circuits, and cooling loops.
