EGE Elektronik Sensor Amplifiers Productseries SKM 420

Description

The EGE Elektronik SKM 420 is the authoritative choice for engineers who prefer a decentralized sensing architecture placing the robust sensor head in the process and the sensitive electronics in the protection of a control cabinet. Unlike “all-in-one” sensors, using the SKM 420 allows you to monitor extreme environments (high heat or vibration) while keeping the calibration and diagnostic tools accessible at the cabinet level. The SKM 420 series is specifically optimized for 24V DC environments. It features a high-quality Relay output, providing a potential-free change-over contact that can easily be integrated into PLC logic or used to switch a direct load. One of its most valued features is the integrated temperature monitoring capability; it can evaluate both the flow velocity and the media temperature simultaneously when paired with the appropriate dual-function probe

Features

Potential-Free Relay Output: Versatile change-over (SPDT) contact for universal system integration.
Adjustable Switch-off Delay: Features a 0…25 second delay to filter out signal noise or turbulent flow.
Temperature & Flow Evaluation: Capable of processing dual signals from specialized EGE probes.

Applications

Industrial Cooling Loops: Monitoring both the presence of coolant and its temperature in CNC or furnace systems.
Lubrication Systems: Ensuring oil flow is consistent to prevent bearing failure in heavy machinery.
Pump Dry-Run Protection: Using the relay output to shut down pumps if flow is lost or the medium exceeds safe temperatures.
