Hydra-Electric Announces New Electronic Temperature Switch at Farnborough International Airshow Addressing Common Failure Issues with Mechanical Switches

New switch provides for greater accuracy and repeatability, even in high vibration environments.

Burbank, CA – July 12, 2016 — Hydra-Electric Company, a provider of breakthrough technology in sensors and switches for the aerospace industry, announced that it will be introducing a new electronic temperature switch. The Company will showcase this and other solutions at the 2016 Farnborough International Airshow, where it is exhibiting in Hall 4, Stand E-61.

This new patent-pending design provides for greater accuracy and reliability, and allows customers to select any setpoint with high accuracy, plus or minus two degrees. Other features include the option of adjustable or selectable hysteresis, settable trip

temperatures, and the ability to provide a window indication – either within a set temperature range or outside that range.

With existing technology, mechanical switches will fail after a certain number of cycles, especially in high vibration environments. By contrast, Hydra-Electric’s new design uses electronic circuitry that extends the life by a factor of greater than ten times (as measured in cycles or time).

“The circuit senses mechanical switch closure to make it look like a constant impedance maintained 10 or even 20 times longer,” said Bob Guziak, Director of Sensor Engineering at Hydra-Electric. “This design addresses the number one complaint we hear from our customers about the short life of mechanical switches, especially in high vibration environments.”

“This product is being shipped now for use in engine systems subject to very high vibration levels,” remarked Tim Burmood, Director of Sales. “In addition, it offers applicability to systems across the aircraft, and can enhance any of our standard Hydra-Electric pressure switches.”
