Data Loggers / Signal Conditioning

Once your sensors have collected valuable data, you definitely do not want to lose the data! Instead, the data must be stored safely until transported to the final destination. This is the function of a data logger. A data logger collects and stores (logs) data from sensors into its memory. Data can be transported from the data logger to their destination in many different ways, including GPRS (mobile phone network), an RS232 or USB cable, satellite communication, or by a radio link.

For most logging and transmission applications, our GPRS data loggers are the best choice. If more input flexibility or PLC functionality is required, refer to our modular or PLC data loggers. The signal conditioning units can concentrate several inputs, typically from meteorological sensors, into a single NMEA stream on RS232.

Data from the data loggers or signal conditioning units can either be displayed on one of our displays, or it can be further processed by our advanced OMC-data online software package.

OMC-045-III GPRS Data Logger

The OMC-045-III GPRS data logger is a low power, high-end data logger with built-in GPRS modem and GPS receiver.

The logger has internal temperature and humidity sensors and has slots for a 2GB SD card and for a SIM card. It provides seamless interfacing to all meteorological and hydrological sensor from Observator Instruments and many more. It supports RS232/422/48, ModBus, NMEA and so on. Thresholds can be set on all parameters. If a parameter exceeds its threshold, an alarm is generated. Data is transferred by FTP or email over GPRS, or by an external satellite or radio modem. Like all other OMC-04x loggers, the 045-III can be configured using the free OMC-Programmer software and a USB cable.

Several housing options are available, including a housing with a touch screen display and/or rechargeable batteries and various connectors.
