Functional safety - Import export

The remote data transmission unit ARC1-Box-SB with logger function is equipped with safety barriers and, in combination with intrinsically safe transmitters, it is suitable for use in hazardous applications. The unit is encased in a robust, water-tight aluminium housing. It records measurements made by external sensors (e.g. a level sensor) and periodically transmits the collected data via 2G, 3G, 4G or LoRaWAN. The high-performance battery and sophisticated power management enable autonomous operation for up to 10 years. KELLER provides a range of licence-free software solutions for configuration and data processing. The easiest and most convenient way to access the collected data is via KOLIBRI Cloud.

The direct operated solenoid valve offers all the advantages of the pilot operated solenoid valve at operating pressures up to 1000 bar, but is even smaller and more compact. Here too, the focus is on cost efficiency and reliability. The direct operated 2-way on/off valve is made of stainless steel and has a monostable design (normally open or normally closed). Its flow factor (KV) is 0.006 m³/h. The direct operated normally closed solenoid valve also has a safety function. In case of a voltage drop, it closes automatically, reliably and tightly.

The ultra-compact and extremely light Nova Swiss solenoid valve is designed for hydrogen and inert gases applications for an operating pressure of up to 1000 bar. Your applications can now be realised even more cost-efficiently thanks to its minimal dimensions. The piloted 2-way on/off valve, manufactured from stainless steel, is monostable (normally open or normally closed). It features a flow coefficient KV = 0.6 m³/h. If the current drops at the solenoid coil, the normally closed valve closes reliably and tightly (safety function).
