Calibration is the comparison and adjustment of a reading from an instrument in correlation with the reading of a higher accuracy piece of equipment. The overall goal of this process is to minimize measurement uncertainty and ensure the accuracy of an instrument.
Many Dwyer Instruments, Inc. products sense and measure pressure. This includes: gages, manometers, transmitters and switches.
Pressure is the amount of force acting on a specific area and is equal to the force divided by the area.
There are many types of pressure that are used and measured, including: atmospheric, absolute, gage, vacuum, differential and hydrostatic. Continue reading “What is Pressure and How is it Referenced?”
Over the years, Dwyer Instruments, Inc. has continuously improved its position as a global leader in designing and manufacturing innovative controls, sensors and instrumentation solutions. This success is due in part to our invention of the Magnehelic® differential pressure gage in 1953. Since then, the market leading Magnehelic® differential pressure gage has been continuously updated and improved. The Magnehelic® gage is a versatile low differential pressure gage which quickly indicates air or noncorrosive gas pressures – either positive, negative (vacuum) or differential. Over the years, among countless other updates, we’ve invented a high accuracy version of the Magnehelic® gage which provides an accuracy within 1% of full scale and created backwards compatible products.

A common flow measuring application is using a Magnehelic® Differential Pressure Gage with a Pitot Tube to measure velocity pressure. This velocity pressure can then be easily converted into velocity or flow rate. Continue reading “Custom Scales for Differential Pressure Gages”
