NH Research Data Acquisition (DAQ) Instruments

NH Research Data Acquisition (DAQ) Instruments

Product Overview:

  • Single box including Voltage, Temp & resistance temperature detector (RTD)
  • 24-bit DAQ-per-channel design
  • Wide measurement ranges
  • Fully isolated channel-to-channel design
  • No test channel-to-DAQ usage dependency
  • Easy expansion to higher channel count

 

More

Each channel provides its own high resolution 24-bit DAQ, a separate per channel measurement range, and each channel is fully isolated from all other channels. This makes it possible for adjacent voltage channels to measure cell voltages as well as module, string and pack voltages at the same time (figure 1). Additionally, temperature measurement channels are independently programmable for each thermocouple type (B, E, J, K, N, R, S, and/or T) allowing any combination of temperature sensors to be used.

 

Major Advantages

This modular approach breaks the traditional test channel to DAQ dependency allowing the measurements from any channel to be utilized by any test. Additionally, the data acquisition to be placed closer to the UUT and with the configuration which best suits the testing needs.

This modular approach has no limit to the amount or type of data acquisition channels, allowing for future expansion of the system. Simply adding additional DAQ instruments can now meet the future testing needs when either capabilities or test requirements increase.

 

Data Acquisition Instrument Options

The most commonly selected DAQ instrument is the DT8874 series which is a modular single box design. This model is available in 8, 16, 24, 32, 40, or 48 versions which may include any combination of voltage, temperature and RTD channels to be specified in groups of 8.
