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).

Liquiphant FTL81 is a point level switch for use in hazardous areas with all international certificates. FailSafe overfill prevention in applications with functional safety up to SIL3 with one device. Reliable measurement values, not affected by: changing media properties, flow, turbulences, gas bubbles, foam, vibrations or build-up.

Liquiline M CM42 is the robust transmitter for pH/ORP, conductivity or oxygen measurement in all process applications. It is the best choice for demanding environments be it hygienic applications, hazardous areas or functional safety areas. Liquiline’s intuitive operating concept simplifies commissioning, handling, and maintenance saving you time every day.

With the second line of defense highest degree of safety and availability of the device can be guaranteed. Reliable measurement values, not affected by: changing media properties, flow, turbulences, gas bubbles, foam, vibrations or build-up.

Micropilot FMR67 is the first 80GHz radar developed according to the international functional safety directive IEC 61508. It offers maximum reliability due to the drip-off antenna, improved focusing and very small emitting angles which is perfect for the measuring in slim silos. FMR67 is used for continuous, non-contact level measurement in powdery to granular bulk solids. FMR67 also possesses the smart sensor functionality Heartbeat Technology.

Micropilot FMR62 is the first 80GHz radar developed according to the international functional safety directive IEC 61508. For applications in aggressive liquids, FMR62 offers extraordinary advantages with its completely PTFE-filled and flush-mounted antenna. The integrated PEEK antenna allows very small process connections. The FMR62 free space radar offers maximum reliability due to improved algorithms and small beam angle. It also possesses the smart sensor functionality Heartbeat Technology.

Liquiline System CA80COD offers constant online measurement of the chemical oxygen demand (COD). It supports you in monitoring the cleaning capacity of wastewater treatment plants and enables load-based billing for industrial dischargers. Automatic calibration and cleaning save operating costs while advanced diagnostics with remote access help to provide process documentation to authorities. The COD analyzer's software-controlled safety functions ensure the highest level of occupational safety.
