(DENT Instruments, Bend, OR)
— DENT Instruments, a global leader in the design and manufacture of power and energy measurement instruments, announced today that it had been granted Patent No. 7,612,552 by the U.S. Patent and Trademark Office.
There is a growing interest in electrical energy metering in support of energy efficiency and conservation as well as utility bill reduction. Electrical power measurement often requires simultaneous measurement of both voltage and current on one, two, or three electrical phases. The PhaseChek™ circuitry quickly and easily indicates to a user when the current sensors of the meter have been improperly wired or connected.
Christopher Dent, President of DENT Instruments explained the importance of this development by saying, “PhaseChek circuitry ensures correct current sensor placement during installation, greatly reducing set-up time, eliminating installation errors, and avoiding costly extra trips to correct a faulty meter installation. A mis-wired electrical meter can be insidious in the sense that it will still measure and record power and energy information–it will just be wrong. Sometimes it takes days or longer for someone reviewing the data from the meter to determine that the data is incorrect and send another crew to check and correct the installation, resulting in higher labor costs and lost data.”
The PhaseChek circuitry is featured exclusively on DENT Instruments’ PowerScout Series of networked power meters
. DENT Instruments was recognized for excellence in product design for the PowerScout in the 5th annual Dealer Design Awards Program sponsored by The Air Conditioning Heating & Refrigeration News magazine earlier this year. An independent panel of 41 contractors acted as judges in the contest that had 124 entries from 84 different brands. The company’s PowerScout was the Silver Award Winner in the Testing & Monitoring Products. The ACHR News is the leading trade magazine in the heating, ventilating, air conditioning, and refrigeration industries.
DENT Instruments is a leading supplier of an array of precision measurement instrumentation and analytical software in the field of energy management.
