Model 8001 LC-1 Single-Channel Datalogger
The Model 8001 LC-1 Single-Channel Datalogger is an easy-to-use instrument for all types of vibrating wire sensors and their internal temperature sensors. It is housed in a rugged, weather-resistant Nema 4X aluminum enclosure designed for use in field environments. Power is supplied by two easily accessible ‘D’ cells or by solar panel for remote long-term applications. 8000 readings can be stored before the oldest data is over-written. Strings of LC-1 dataloggers can be daisy chained using the RS-485 interface and versions are available with radios and modems to provide remote readout capabilities. Complete with Windows® based user friendly software.

Program Memory 32K ROM
Data Memory 128K SRAM
Temperature Range –40°C to +60°C
L x W x H 115 x 115 x 80 mm

Model 8001-2 LogWare Software
LogWare simplifies the task of configuration, communication, monitoring, data collection and data reduction using the Geokon Model LC-1 datalogger. The configuration, data collection and monitoring form includes a screen for measurements, intervals, connection and data collection configuration, a real-time text based monitor, a graphical monitor and terminal emulator. The data reduction form includes a data file editor, Excel compatible spreadsheet and charting component. The spreadsheet can load and save Excel v4.0/5.0/95 files and create HTML tables for use on the internet.

Model 8020 MICRO-10 Datalogger
The Model 8020 MICRO-10 Datalogger is a versatile low-cost instrument capable of reading practically all types of electrical sensors such as vibrating wire transducers, linear potentiometers, DCDTs, RTDs, thermistors, thermocouples, accelerometers, etc. The heart of the Micro-10 Datalogger is the Campbell Scientific CR10X MCU which serves as a microcomputer, clock, multimeter, calibrator, scanner, frequency counter and controller. The Micro-10 comes in a sealed weatherproof Nema 4 enclosure and includes the Model 8020-47 DSP filter for the elimination of spurious noise effects. User friendly Windows® based MultiLogger software allows easy programming of scan intervals, selection of sensor types, setting of alarms, etc. Data is retrieved by telephone modems, solid state storage module, radios, or satellite transmission.

Model 8032 Multiplexer (MUX)
The Model 8032 Multiplexer expands the number of channels that can be read by the MICRO-10 Datalogger or GK-403 Vibrating Wire Readout Box. The channels are protected against voltage surges with tripolar plasma surge arrestors and bipolar surge arrestors. Optional manual switches may be connected to the terminal board that permit easy access to each channel of the multiplexer for taking manual measurements with a portable readout in tandem with those taken automatically with the datalogger.

Model 8020 MultiLogger Software
MultiLogger is designed to get a Micro-10 data acquisition system up and running in a matter of minutes while still retaining the power and flexibility of the Campbell Scientific CR10X Controller. The program provides for selection of interval types and for channel configuration via direct connection to the controller or through multiplexers. Measurement channels can be configured for instrument type and programmed to output temperature corrected data in engineering units. Alarm limits can also be specified.
