Jupiter, Fla. -- ISO 50001, Energy management systems – Requirements with guidance for use, provides organizations big and small with a framework for establishing, implementing, maintaining and improving an energy management system. Effective energy management practices save businesses money on energy costs as well as help to conserve resources. With ISO 50001 currently under revision, organizations should focus on hard data when making energy management decisions.

Data loggers are essential tools for the measurement, documentation and reporting of energy use and consumption. When conducting industrial and office energy audits, data loggers are used to monitor electrical power consumption and heating, ventilation, and air conditioning (HVAC) system efficiency by recording measurement data related to current, voltage, temperature, humidity and air flow. Data loggers capture these measurements in intervals, providing an accurate survey of energy consumption and use over time. To determine the right data logger for your application, consider your requirements for the following:

  • Measurement accuracy For example, when monitoring HVAC efficiency in an office space, you may require a temperature measurement accuracy of +/- 2 degrees. However, when monitoring HVAC efficiency in a warehouse storing temperature-sensitive products, you may require a much greater accuracy. 
  • Memory or storage capacity Memory size relates to the maximum number of readings a data logger can record. Take into account the length of time you will be conducting your energy audit. Also realize that when data recorders are used with different input channels, their maximum memory capacity only refers to one channel. If you use a data logger with four input channels, maximum memory capacity has to be divided into four parts. For example, a four-channel data logger with a maximum memory of 32,000 bytes offers 8,000 bytes for each channel. 
  • Data access A data logger with an RS 232 interface, USB port or SD memory card allows for convenient data transfer to a computer via a cable, flash drive or SD card reader. Web-based data loggers allow remote access, but typically come at a premium price.

PCE Instruments offers accurate, affordable data loggers for the effective energy auditing of industrial plants, manufacturing floors, climate-controlled storage facilities, research laboratories, office buildings and more.
