DataMite Mini, DataMite III and DataMite 4 USB Hardware

Our DataMite data loggers have been used on dynamometers, in drag racing, circle track racing and road racing since 1995.  These latest loggers take advantage of all the advancements in electronics to provide very powerful data logging features at a very affordable price in a very compact package.

DataMite Mini USB

Communicates with computer via USB to record 2 RPM channels and 2 0-5 volt analog channels.  Has option for adding "built in" weather sensors and recirculating fan.  This is an ideal package for a small dyno, inertia or absorber (water brake, eddy current, hydraulic), engine only or chassis dyno.  Note:  System has very limited expandability for adding sensors.


DataMite III USB

Our 3rd generation of DataMite data logger, has several advanced features for dyno or vehicle data logging.  With its surface mount technology, we've been able to pack lots of power into a very small package.  It's only 4.2 x 5.6 x 1.7 inches (mounting flanges and hardware make the "footprint" larger) and weights less than 1 lb.  It can be used for a dyno system, or in drag racing, road racing or circle track racing.  It's main features include:  

  • DataMite III USB with 3 RPM channels and 12 analog channels.

  • 3 axis accelerometer

  • USB communications cable for data recording or setting up and troubleshooting

  • 1 Gig (1000 meg) or optional 2 Gig SD memory card, provides hours of recording time and incredibly fast uploading to your computer for analysis.

  • Lighted Start/Stop logging switch

  • GPS enabled for optional DT3-GPS allowing for GPS track mapping and lap timing for Road Racing/Circle Track systems.

  • 50 or 100 Hz sampling rate

 The GPS feature is truly powerful, providing very accurate track maps, letting you compare the line taken on different laps.

Our newest DataMite data logger is basically our DataMite III described above with more channels.  It's additional channels include:

  • 4 RPM (frequency) channels (1 more than DataMite III)
  • 10 possible thermocouple channels (6 more than DataMite III)
  • 12 dedicated user definable, analog channels
  • 2 possible weather channels (which, if used, do not reduce the number of analog channels, as was the case with DataMite III)
  • 1 box temperature channel
  • 1 power voltage channel
  • 3 axis accelerometer
  • 3 GPS channels (latitude, longitude and speed)
  • 4 digital inputs channels (not available with DataMite III)  
  • 2 digital outputs, like rev limiter or oil pressure cutoff, shift light, etc. (is not available with DataMite III)
