Differential Pressure Logger

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 remote data transmission unit ADT1-Box is encased in a robust, water-tight plastic housing. The LoRa module, which can be configured on a country-specific basis, establishes a connection with the Internet and makes it possible to collect measurement data in a low-cost and energy-saving manner. These autonomous devices can be linked with digital level sensors and pressure transmitters in the KELLER D and X product lines. With three conventional, high-quality AA batteries, the system can operate autonomously for up to 5 years. The LoRaWAN provider can be selected freely or an in-house or open source infrastructure and associated services can be used. The easiest and most convenient way to access the collected data at the end of the transmission chain is via KOLIBRI Cloud from KELLER.
