DataLogger
measuring and recording of physical quantities to the SD-Card
Datalogger is a measuring and recording device to the SD-Card. Typical recorder quantities are voltage, current, temperature,
pH, force, pressure.
Currently there are two devices working.
Industrial DataLogger System9
Datalogger is a device recording voltage 0-26V and temperature 10-350°C from termocouples. Measured signals are connected through connectors. Measured data are transfered to the PC using standard SD-Card reader and loaded to Excel for further processing.

- Measured analog quantities:
- 2x temperature from termocouples 10-350°C
- 6x voltage 0-26V
- Sampling period 10 samples per second (downsampled)
- Measured data recorded to the SD/Card
- Measured data are loaded to the Excel by a supplied software.
- All input signals are galvanicaly isolated from each other, every input signal has its own isolated floating ground.
- Signal fro, termocouples is by a compensated connector and inner wires conducted to the inner compensating absolute thermal sensor of the cold end. The compensator is settable to the various types of thermocouples.
- Datalogger is portable, analog inputs are lead to the 25 pin Canon connector. This allows to instal the probes firmly at several measuring places.
- Termocouples are connected through standard mini MPJ connectors distinguished by color according to the ASTM standard.
- Device is powered from the external adapter backed up by internal lead accumulator.
- Datalogger control: start a stop buttons and a signal LED lamp
- Maximal time of record depends on SD-Card capacity. 2GB can held up to 11 days of continupus recording.
Miniature scientific DataLogger
A tiny autonomous device for measuring high temperatures in ten locations 2000 times per second and storing the data on the SD-Card. This device is developed for recording temperature variations during experimental plasma coating. DataLogger is placed together with rotating samples in the plasma chamber and cooled by water. After the measurements, the recorded data are loaded from the SD-Card to the computer by a special software into the CSV file format.Block schematics of the DataLogger
