Technical description of the installation
In the dairy a 2-wire bus system is installed together with a central computer. In each of the 12 cold storage rooms a PT100 standard temperature sensor and a DPBIT34-A1 sensor-amplifier registers and transmits data to the central computer through the bus system. The computer is linked to the bus system via a BIT2011 server.
Digital DPBIT40 output components makes it possible for the customized Bitlink software to actively control the refrigerator compressors, and therefore the temperature of the cold storage rooms, via the same 2-wire bus system.
The system also detects if any of the compressors have even small operational problems. DPBIT50 input components are used for this purpose.
All data is kept in a log in the Bitlink software which also contains the temperature profiles used in the facility and lists of people to alarm in case of any problems.
