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.

Why is pressure sensor accuracy important? From a manufacturer’s point of view, the wrong sensor can cause expensive quality or efficiency problems. This is why it’s important to understand how manufacturers calculate accuracy and recognize what parameters to look at when comparing pressure sensors.
By understanding how manufacturers calculate accuracy, you will be able to make a more informed decision when evaluating pressure sensors. This ensures that the next sensor that you select will have the required accuracy at the right price for the application. Continue reading “Pressure Sensor Accuracy”
Technology markets shift. The shift can be incremental, radical, or sometimes disruptive.
Take, for instance, gages used in process automation markets. Gages command about $3.5 billion in global instrument sales, the major portion, over $11 billion now held by transmitters.
The technological shift from a visual indication gage to the first transmitter has been incremental. It has taken over 50 years for transmitters to go from concept to commanding 70% market share. Continue reading “Market Shifts & the Need for Backward Compatible Products”
