IC MEMORY CARD DATA LOGGER
1. Purpose and objectives
To measure signals from various sensors and store the data into integrated circuit (IC) memory card for off-line data processing.
The Memory Card Logger is designed so that measured data can be stored on an IC memory card and later analysed with a personal computer.
As the logger is designed for low energy consumption, it can operate on a battery pack (alkaline dry cell batteries) or on DC power if commercial power (AC) is not available. Furthermore, long term data recording without an AC power supply is possible due to one of the standard features of the logger, an interval measuring mode by which the power is automatically turned off during periods when measurements are not being made.
Either thermocouple, resistance bulb, or DC voltage to each channel can be selected for the input. A special terminal for inputting either frequency or pulse is a standard feature. Also make-break signal transmission for input and output can be selected at the time of ordering. In addition to data storage on the IC memory card, printouts, such as list printouts, can be carried out with the built-in printer.
Setting can be carried out very easily with the keyboard on the front panel, and setting contents stored on the IC card are easily recoverable.
Products for the GP-IB and RS-232C communications functions are also available (sold separately).
The logger can record from up to 32 input points at an interval from 1 min. to 6 hours. The following types of input are available:
0-30mV, 300mV, 3V, 30V, and 1V-5V
Type R, S, B, K, E, J, T
Resistance Bulb: Pt 100 ohm, JPt 100
0Hz-10Hz Max. count number is 29999
Data stored on an IC memory card, (Max 512 Kbyte), as a listing, on a digital display or as a digital signal to GP-IB or RS-232C standards (optional).
5. Operational requirements and restrictions
The logger requires a regulated power supply and the installation must avoid vibration, high temperatures and humid conditions.
6. Form of presentation
A catalogue and instrument specifications are available.
7. Operational experience
About 30 sets were installed in Japan during 1999.
8. Originator and technical support
Yokogawa Denshikiki Co.,Ltd.
10. Conditions on use
Hardware is for sale.
