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.

The DCX-38 data loggers are designed for water level measurements with a high resolution in the mbar range. They can detect water levels with a total error band of just 1 mm (measuring range 0,5 m water column, compensated temperature range -10...40 °C). Thanks to their long-life battery, they can keep measuring the water level, water pressure and temperature for years (up to 10 years at a rate of one measurement per hour). The logger can be configured using the supplied software (measurement interval, incident management, delayed measurement start etc.) and data that has been read can be displayed in a graph or chart, converted into fill levels or other units, and exported.

The DCX-22AA-CTD data loggers measure conductivity and temperature as well as pressure, along with the depth of bodies of water. They compensate for the air pressure using an additional, water-tight absolute pressure sensor with a stainless steel separating diaphragm. Unlike gauge pressure systems with a capillary tube, this system is completely resistant to moisture and can therefore be immersed. Thanks to their long-life battery, they can keep recording measurement results for years (up to 10 years at a rate of one measurement per hour). The logger can be configured using the supplied software (measurement interval, incident management, delayed measurement start etc.) and data that has been read can be displayed in a graph or chart, corrected using air pressure values, converted into fill levels or other units, and exported.

The DCX-22-CTD data loggers measure conductivity and temperature as well as pressure, along with the depth of bodies of water. The integrated Pt1000 achieves an accuracy of ±0,1 °C, and the conductivity can be measured at ± 2,5% of the selected range (0,2 / 2 / 20 / 200 mS/cm). Thanks to their long-life battery, they can keep recording measurement results for years (up to 10 years at a rate of one measurement per hour). The logger can be configured using the supplied software (measurement interval, incident management, delayed measurement start etc.) and data that has been read can be displayed in a graph or chart, corrected using air pressure values, converted into fill levels or other units, and exported.

The DCX-25PVDF data loggers have been specially designed for use in aggressive liquids such as brackish water and sewage. The housing is made of polyvinylidene fluoride and the installed pressure transducer is available in Hastelloy C-276 or titanium 6AL-4V. Thanks to their long-life battery, they can keep measuring the water level, water pressure and temperature for years (up to 10 years at a rate of one measurement per hour). The logger can be configured using the supplied software (measurement interval, incident management, delayed measurement start etc.) and data that has been read can be displayed in a graph or chart, corrected using air pressure values, converted into fill levels or other units, and exported.

The DCX-16 data loggers have a diameter of just 16 mm and can be used in tight spaces. Thanks to their long-life battery, they can keep measuring the water level, water pressure and temperature for years (up to 10 years at a rate of one measurement per hour). The logger can be configured using the supplied software (measurement interval, incident management, delayed measurement start etc.) and data that has been read can be displayed in a graph or chart, corrected using air pressure values, converted into fill levels or other units, and exported.

The DCX-22AA data loggers compensate for changes in air pressure by means of a separate, water-tight absolute pressure sensor with a stainless steel separating diaphragm. Unlike gauge pressure systems with a capillary tube, this system is completely resistant to moisture and can therefore be immersed. Thanks to their long-life battery, they can keep measuring the water level, water pressure and temperature for years (up to 10 years at a rate of one measurement per hour). The logger can be configured using the supplied software (measurement interval, incident management, delayed measurement start etc.) and data that has been read can be displayed in a graph or chart, corrected using air pressure values, converted into fill levels or other units, and exported.

The DCX-22 data loggers achieve greater measurement accuracy than loggers with a smaller diameter. Thanks to their long-life battery, they can keep measuring the water level, water pressure and temperature for years (up to 10 years at a rate of one measurement per hour). The data logger can be configured using the supplied software (measurement interval, incident management, delayed measurement start etc.) and data that has been read can be displayed in a graph or chart, corrected using air pressure values, converted into fill levels or other units, and exported.

The low-cost data loggers of the DCX-18-ECO series have a rechargeable battery encased in a fully welded steel housing. The configuration software supplied (measurement interval, incident management, delayed measurement start etc.) also makes it easy to display data that has been read in a graph or chart, correct it using air pressure values, convert it into fill levels or other units, and export it.

The ultra-fast M8coolHB pressure transmitter can process pressure changes with a bandwidth of 50 kHz. This is achieved by means of the continuous analog signal that is adjusted by a digital circuit in real time and is amplified to a standardised 0...10V signal. The miniature sensor head with a fine M8 thread can withstand temperatures of up to 1000 °C with suitable cooling, is overload-proof up to a magnitude of five times the measuring range, and is also resistant to vibrations.

The ultra-fast M5HB pressure transmitter can process pressure changes with a bandwidth of 50 kHz. This is achieved by means of the continuous analog signal that is adjusted by a digital circuit in real time and is amplified to a standardised 0...10V signal. The miniature sensor head with a fine M5 thread can withstand temperatures of up to 180 °C, is overload-proof up to a magnitude of five times the measuring range, and is also resistant to vibrations.
