Data loggers

[teenix]

I used to work at Monash Uni and used a few different data loggers for various things, but mostly strain gauges, LVDT's and accelerometers.

All you can really do is read the spec sheet for the logger types and the sensors that you want to connect, then see if the logger inputs are compatible with the sensor outputs or if you need something in between to make them compatible.

For example, if the logger only reads voltages, then a sensor that outputs changes in current won't work without some signal conditioning. Some sensors need external power as well, while others may be able to be powered by the logger. Thermocouples may need some sort of mathematical translation to get a valid reading from them. Some sensors output digital signals which may or may not work with the logger.
