The Model 8002-1 (LC-2) and Model 8002-1A (LC-2A) are stand-alone, single-channel dataloggers, designed to read both the vibrating wire element and the integral thermistor of any Geokon vibrating wire sensor. The LC-2 offers an internal hard wired transducer connection and the LC-2A provides an optional 10-pin transducer connector for rapid sensor connection. The dataloggers are housed inside a Fiberglass Nema 4X enclosure, are very robust, weather-proof and particularly well-suited to operation in harsh environments. Power is supplied by two easily accessible ‘D’ cells or by solar panel for remote long-term applications. Data memory consists of 320K bytes of EEPROM, which translates into a memory storage capacity of 16,000 arrays. Each array consists of the datalogger ID, day (Julian or month/day format), time (HHMM), seconds, main battery voltage, datalogger temperature, vibrating wire sensor reading (in engineering units), the sensor temperature and array number. The array transmission is in comma delineated ASCII text, for easy importation into popular spreadsheet applications. Configuration, communication, monitoring, data collection and data reduction are achieved using LogView Software.
