HM670 and HM680 hydronic manometers measure differential and gauge fluid pressure to balance heating and cooling systems or check pump performance. Both models can measure and display differential, ...

The analog manometer, commonly referred to as a Magnehelic ®, is a test instrument that has been around the HVAC industry for decades. Among many technicians in the field, it is still the test ...

Piezoresistive (diaphragm-based) differential pressure sensors based on silicon comprise a thin silicon diaphragm in which resistors (connected together in a Wheatstone bridge) are lodged. If there is ...

Manometers are used by engineers and technicians to measure and monitor pressure, and the selection of the best-for-application device is based on a number of critical elements such as high accuracy, ...

Pressure measurement applications may require simultaneously measuring differential and gauge pressure, often employing two separate sensors with different reference points. However, this solution is ...

In the 1950s, temperature-equalizing columns were commonly used in steam drum differential pressure–based devices for measuring water level. However, these columns are problematic because a portion of ...

Some of the applications mentioned here require a room that maintains a higher or lower pressure compared to the surrounding ambient environment. If the isolated room has greater air pressure, it is ...
