Two channel 12-bit voltage data logger with counter channel

Features

• Log interval from 1 minute to 1 day
• Records 1 or 2 single ended channels, 0 to 2.500 vdc
• 16 bit counter channel
• Resolution: .6104 millivolts
• Accuracy: +/- 0.6104 mv +/- 0.1% of reading from -10 to 60 degrees
• Precision switched 2.500 vdc supply (50 milliamps max).
• Logger can be given a unique ID.
• Current consumption < 200 microamps while logging.
• Power requirements: 6 to 18 vdc.
• Data is easily imported into a spreadsheet.

Additional features of this logger include protection against accidentally attaching the power supply backwards, a combination of zener diodes and transient voltage suppressors on both the inputs and outputs to protect against voltage transients/short circuits. The 2.5 vdc switched supply features a user set delay to allow the sensor output to stabilize before the measurement is made(1 to 25,000 milliseconds).

Requirements for use

• A PC running HyperTerminal (standard on Windows 95, 98, NT) for configuring the logger and collecting data.
• A standard 9 pin male/female RS232 cable.
• A suitable power source( 6 to 18 vdc).
• An enclosure to provide environmental protection for the datalogger.

Data storage

The number of time and date stamped samples that can be stored depends upon the number of channels selected for recording.

• Recording 1 channel      18,724
• Recording 2 channels    14,560
• Recording 3 channels    11,912

The contents of memory will be retained for up to ten years in the absence of power.

Setting the logger up is simple.

• Set the real time clock.
• Set the log interval.
• Set the number of channels to record.
• Set the delay value to allow the sensor(s) output to stabilize.
• Give the logger a unique I.D.

All settings are retained in non-volatile memory until changed by the user.
