Data logger COMBILOG 1022
in
The COMBILOG 1022 is a data logger with compact design, combined with integrated LC-display and memory slot suitable for SD cards. This data logger was developed for meteorological, hydrological and environmental measuring systems, but it is equally suitable for countless further applications in industrial production. The COMBILOG 1022 features high performance, compact design (SMD components), low power consumption and moderate price
The most varying measurement tasks can easily be accomplished by means of the COMBILOG 1022. Some typical applications are e.g. measurement of temperature via resistance thermometers (Pt100), operation with combined sensors with current- or voltage output (e.g. wind speed measurement with DC generator) or position measurement and weight measurement by displacement transducers and force transducers. With these applications the data logger COMBILOG 1022 supports measuring methods with 2-, 3- and 4-wire technique. The signal processing required in accordance with the sensors used, such as gain, linearisation, offset correction etc. can be adjusted individually by software. An external amplifier is not required.
The digital signal inputs can be used, for example, to connect switches, initiators, digit emitters and oscillators. Thus status indications can be collected and tasks like e.g. position measurements, displacement measurements, angular measurements, frequency measurements and timings can be carried out. Furthermore special 8-bit-Graycode-transmitters can be connected. Special calculations of measured values are possible by arithmetic channels. In case the 8 analogue and 6 digital inputs are not sufficient, other modules can be connected to the data logger via the RS485 bus. In this case the COMBILOG is used as a bus master to read the measured values from the slave modules.
All data can be transmitted via the integrated RS485 communication interface to a subsequent control (PLC) or to a computer (PC). Up to 127 modules can be connected with the two wire line over distances of several km. At the same time the communication interface features programming and configuring the individual application from a PC. If the data logger COMBILOG 1022 is not integrated in a bus, an additional RS232-interface is available for the user. This interface allows only a point-to-point connection up to max. 20 m (65 feet), but all functions of the RS485-interface remain available. Furthermore the data logger can send messages in case of user definable conditions automatically via modem or SMS. A configuration program is included
