EGE Elektronik Sensor Amplifiers Productseries SKM 420 GSP

Description

The EGE Elektronik SKM 420 GSP is the authoritative choice for engineers who require rapid response times and long-term durability in their flow monitoring systems. By utilizing a PNP transistor output, the SKM 420 GSP eliminates the mechanical lag and contact wear associated with traditional relays. This makes it particularly effective for applications involving frequent switching cycles or high-speed data logging. As part of EGE’s decentralized sensing philosophy, the SKM 420 GSP allows the sensor probe to be placed in harsh process conditions (high pressure, vibration, or temperature) while the sensitive evaluation electronics remain protected in the control cabinet. The unit acts as a 24V DC bridge, powering the remote probe and interpreting its calorimetric data into a clear “Flow/No-Flow” electronic signal.
