Certificates of Calibration Explained

Dwyer Instruments, Inc. offers a variety of calibration services for new or previously purchased products. In 2019, the Dwyer Instruments, Inc. – Engineering Laboratory, located in Michigan City, IN, gained accreditation to ISO/IEC 17025:2017 through the ANSI National Accreditation Board. The Dwyer lab now offers two different types of calibration certificates for our products: a certificate of NIST calibration and an ISO/IEC 17025:2017 accredited certificate of calibration. Now that accredited calibration services are available for select Dwyer products, it is important to know the differences between these two different calibration certificates. Knowing these differences will allow you to understand which calibration certificate will best suit your needs. Continue reading “Certificates of Calibration Explained”

Decrypting Thermal Energy Meter Accuracy

“Simplicity is the ultimate sophistication” – Leonardo da Vinci

These days, energy conservation is on everyone’s mind. From cost savings to environmental concerns, there are many well-known benefits to conserving energy. But understanding exactly how to do so can be confusing. In order to conserve energy, you must know precisely how much energy you are using.

There are many different methods and tools that can be used to measure your energy consumption, depending on your application. In this post, we will focus on thermal energy measurement and management in hydronic systems. In keeping true to Da Vinci’s quote, we will keep our explanation as simple and straightforward as possible.

How to Set Up and Record with a SCD and Mini-Node™ Signal Converter

The DIN Rail Temperature/Process Controller, Series SCD, offers multiple PID loops in a compact size. Each SCD-1000 master controller can be combined with up to seven SCD-2000 slave controllers without any wires. Each controller has one universal input, one relay output, and one user selected output.

The Series SCD can be used with a Mini-Node™ Signal Converter for applications such as: oven, boiler, or chiller control; packaging equipment; environmental chambers; medical equipment; or food service equipment. The Mini-Node™ converter, Model MN-1, is a low cost device that converts half duplex RS-485 serial communications signals into a signal that can be read by any computer with a USB port.

Wiring up the MN-1 to an SCD controller can be accomplished in just a few steps, and the set up software is simple to use. Continue reading “How to Set Up and Record with a SCD and Mini-Node™ Signal Converter”

The Key to Energy Efficiency

“In the real estate industry you always hear this phrase, ‘Location, location, location.’ I think for energy management systems the key is ‘Execution, execution, execution.'”[1]

— Sara Lisauskas, Energy Management Systems: Maximizing Energy Savings

What comes to mind when you think of the phrase “energy efficient?” Perhaps you think of LED light bulbs, electric cars, Energy Star appliances, or LEED-certified buildings. But energy efficiency isn’t limited to “green” products or certifications. Continue reading “The Key to Energy Efficiency”
