EGE Elektronik Sensor with Integrated Amplifier Productseries STC 425 K

Description

The EGE Elektronik Sensors with Integrated Amplifier Productseries STC 425 K is the authoritative choice for operators who require “at-a-glance” diagnostics of their fluid systems. While standard sensors only provide a binary switching state, the STC 425 K features a linear LED bargraph integrated into the sensor head. This allows maintenance personnel to see how close the flow is to the switching point, enabling the detection of clogged filters or pump degradation before a system shutdown occurs.
