Data loggers


• A/D Converter 31500-usb
12bit A/D converter, resulting in 2x 1800 divisions. The resolution is 6mV when using the ±10V range.

• Analog inputs
True differential inputs.
Input impedance between + and - are more than 400k Ohm and min 5MOhm to reference ground.

• Power supply
12 Volt DC makes the PC-Logger simple to connect to battery supply

• Detachable screw terminals
Use the detachable screw terminals to measure on many different places without unscrewing the sensors.

• Adjustment/Calibration
All channels are software adjusted in the factory. Adjustment constants are stored in the logger and used to calculate the measurements. No oldfashioned potentiometers are used to adjust the logger response.

Options and accessories

Software range switching

Match the signal from your sensors and select the input range. Use your computer to select the range.
Available ranges are:
±10V, ±1000mV, ±100mV, ±50mV, 20mA and thermocouples

Galvanic isolation

The isolation can be fitted within the logger, or alongside the logger mounted in a Pelicase.


Display and 64kB memory

This is a must for the logger when you want to make off-line recordings.
The memory can hold more than 30 000 values. For example, measure with 4 channels each 5th minute and the memory will hold a 28 days long recording. Use the "Multimeter" on the logger when connecting transducers. Every value stored uses two bytes.

Expansion memory

If you want to do long recordings, you may need an expansion memory. The memory is available in two sizes: 512k or 1Mbyte. Every value stored uses two bytes.

Digital card, Pulse counters

For use as status inputs or pulse counters. 8 digital status inputs together with 4 relay outputs makes this card very flexible.

With the option "Pulse counter" you will have 6 counting channels.

Jack panel

Quick and safe. Change transducers simple. The jack panels are configured to your requirements.
External jack panel available upon request.

Wall bracket

When you want to mount the logger on a wall.
