Level control is used in applications where fluid is being moved, monitored, or otherwise included in the system. Crouzet level control relays work by taking input from two level sensors, such as ...

The signal attenuates severely when passing through air, but the presence of liquid greatly enhances transmission. Thus signal strength of the ultrasonic burst serves as the sensing mechanism. Upon ...

Real switches and relays exhibit a finite resistance called “contact resistance,” which increases over time with the number of actuations. Furthermore, as a switch or relay changes state, the contacts ...

Liquid-level switches used in aircraft, nuclear-power plants, medical equipment, and other critical applications must be precise and reliable. For that to happen, design engineers must know the ...

As automotive engineers continue to implement more electronics on vehicles and tighten specifications and expectations for high reliability, the venerable mechanical relay has become endangered. A new ...

When to use mechanical vs. solid-state devices. The parameters that should be considered when selecting a device. Optimize your selection for lowest cost/maximum ...
