Mobile Data Acquisition (DAQ) Stand

A custom, mobile data acquisition stand was designed and built by MD Instruments for the purpose of logging data and controlling aspects of a test cycle programmed to customer specifications.


Data logged includes 68 thermocouples, pressure, humidity, AC voltage, and AC amperage, and apparent power

Data Acquisition Summary

  • 132 delimited data points including all sensor data, calculated values, timers and totalizers.
  • 10-3600 second variable sampling rate.
  • 2 Data vs. Time trend screens for critical tests monitoring, with each trend capable of 16 parameters.


  • Input: 220VAC 30 Amp 50/60 Hz
  • Output: 220VAC 16 Amp (30 A peak) 50/60 Hz

Special Custom-Designed Projects

MD Instruments has engineered a wide variety of special projects which utilize our expertise in process control, data logging, digital communication via Ethernet and radio remote transmission. Most of our projects utilize OPTO 22 hardware and software for the reason that the hardware is high quality and reliable, and the software is free.

Examples include:

  • Tank level monitoring for the municipal water supply system utilizing radio communication for a western Michigan community.
  • Heat monitoring of induction hardened bars utilizing infrared sensors for temperature measurement.
  • Controlling and monitoring of a baghouse facility for a local aluminum foundry.
  • Custom designed and assembled power monitoring stand with frequency variability and ancillary pneumatics for a food service equipment supplier seeking Energy Star ratings from the US DOE and EPA.
  • Furnace temperature monitoring and display system utilizing Ethernet communication to centralized computer and multiple displays
  • Flare gas ignition system for a large scale bio-digester converting waste into methane fuel.
  • Environmental monitoring and data logging system for a large document storage facility.
