Data Logging






Data Logging Can Verify

your savings and operating costs

Businesses that are thinking about upgrades to their facility should verify energy usage before & after. This service applies to lighting, HVAC-R, electrical motors, etc.

LED lighting has been going strong for several years. depending on how many HPS or high wattage lights that are being replaced will depend on savings.

Pre & Post data logging: To know exactly how much energy that is being saved we would install our data loggers onto the incoming high voltage "legs" in breaker panel. One week in this application would be accurate. Now that we know how much power is being used on the lighting then proceed with your install. Once the install has been completed we again install our loggers to get a new reading. We can provide exactly how many KWHs used and saved. 

Of course this is just one application out of hundreds.

Electrical motors, condensers, generators, compressors, refrigeration systems, data centers, the list goes on and on.  

Data loggers (also data logger or data recorder) is an electronic device that records data over time or in relation to location either with a built in instrument or sensor or via external instruments and sensors. Increasingly but not entirely, they are based on a digital processor (or computer) .Data loggers address a wide range of applications, both for general- and special-purpose situations. Special-purpose data loggers are available for, electrical, temperature and humidity, voltage, thermocouple, and event applications to name just a few.

Data logging is the process of monitoring various physical conditions and recording them over an extended period of time. The collected data is accessed and then observed and analyzed at a later date.  Data logging is not to be confused with data acquisition. While data logging is a type of data acquisition, it uses a lower sampling rate (seconds, minutes, hours, or even days). Data-acquisition systems sample data at high speeds (kS/s, MS/s, GS/s) for real-time monitoring and analysis as well as recording.

Some of the typically monitored physical characteristics include:

• Temperature (the most common)
• Humidity
• Pressure
• Liquid flow or level
• Mechanical position
• Strain
• Load
• Vibration
• Light level
• Current, voltage, or power
• Event occurrence
• Wind speed
• Time of use
• Others

Below is a spread sheet outlining temperatures and humidity inside of a building. Blue graph line indicates humidity and black line indicates temperatures in a 24 hour period. Yes this building has humidity issues. 

Data Logging

We provide a wide range of data loggers to get the accurate answers when analizing buildings. 

Data Logging

On a larger scale we provide data logging to collect data on electrical, temperatures, amps, watts and loads.  We can place dozen's of loggers on electrical, mechanical, HVAC, lighting to record operational use for days, weeks and months.

Pin pointing an issue: For example lets say there is 150 HPS "high pressure sodium" 1000 watt light fixtures on parking lot poles. And lets say these lights are on a timer for 12 hours on 12 hours off. Yes you could do the calculations and figure out approx how much KWHs are being used. However other factors come into play. The ballast at each fixture using additional KWHs. Then there is line voltage resistance that uses KWHs. How much? No one really knows that answer unless it has been measured. At the breaker panel we place a data logger on each line voltage load that provides power to the light fixtures. The data logger will record amps & load. It will also measure on and off time.  

Now we have recorded accurate data needed to calculate how much this is costing.

ROI: Return on investment. Once we have figured out the electrical usage and operating costs for those light fixtures then we can review the costs for new LED lighting. After the new lighting has been installed we can once again return to record electrical usage on the new LEDs. Now the recorded data from before & after can be reviewed. This is the only way an accurate assessment of electrical usage and ROI can be determined. 

 DataLoggers recently provided the stand-alone condition monitoring solution for a factory producing machine parts. Worn down by years of use, an electric motor critical to the business would occasionally fail due to extended operation at high temperatures. This would often cause process delays or shutdowns, hurting profitability.

To conduct predictive maintenance, the factory needed reliable condition monitoring before problems could get worse, and also required local alarm notification when temperatures went above 160°F.

Example: Large warehouse freezers, are they performing efficiently?  HVAC systems? Gas fired equipment? Lighting? Once data has been gathered and reports are developed so we can then determine the best solution to lower your overall utility usage. Data rooms or clean rooms need to be controlled for temperatures and humidity. This involves HVAC and mechanical. Most of the time these rooms remain vacate with no employees. How do you know 24/7 what the environment is? Data logging covers a wide range of possibilities. Office buildings, storage facilities, manufacturing facilities, clean rooms, hospitals, restaurants, hotels and even residential.
