EGE Elektronik Sensor with Integrated Amplifier Productseries STB 450 K

Description

The EGE Elektronik Sensors with Integrated Amplifier Productseries STB 450 K is the authoritative choice for operators who need instant, on-site diagnostics for their fluid systems. The “STB” series is specialized for its visual interface; unlike standard flow switches that only indicate a binary “on/off” status, the STB 450 K features a linear LED bargraph integrated directly into the sensor head. This allows technicians to see how close the actual flow is to the switching setpoint, enabling the identification of deteriorating flow conditions before a system-critical alarm is triggered.
