Testing data acquisition systems for use in HVAC system monitoring Conference Paper uri icon

abstract

  • The monitoring of building energy conservation retrofits for purposes of verifying savings usually requires the use of microprocessor-based data acquisition systems that remotely capture data from important monitoring points. Many small, robust data loggers are available that appear to be well suited to this task. However, one is now faced with the daunting task of choosing a system from dozens of manufacturers. This choice is further complicated by a lack of standard communication protocols, and worse yet, no standardized tests for reporting their capabilities. This paper reports on a battery of tests that were developed and applied to nine data loggers, including tests for analog inputs at varying temperatures, and digital pulse tests.
