Steam pressure limiter ES-20

gassingle-stage4-20 mA

The devices of the ES-2x series are electronic safety switching devices for pressure monitoring with comprehensive self-diagnostic functions and fail-safe design. The devices are used as pressure regulators, for minimum or maximum pressure limitation on compressors in refrigeration and air conditioning systems, on heat pumps, steam boiler systems and on hydraulic systems. With the exception of the integrated switching relays, there are no mechanically moving components, resulting in high vibration resistance and a long service life. The switching limits can be conveniently set and precisely monitored. Comprehensive self-diagnostic and logging functions ensure safe monitoring and fast shutdown of the source of danger as well as high traceability of events that have occurred. Special characteristics Simple and precise setting of switching thresholds, reset values and delay times Robust, industrial-grade and fail-safe design Measured value and alarm indication on the display
