The difference between diaphragm pressure gauge and diaphragm pressure gauge
Thread Content
Are diaphragm pressure gauges and diaphragm pressure gauges the same type of pressure gauge? What are the differences?
Diaphragm pressure gauge measures micro pressure ~
Diaphragm pressure gauges are used to measure viscous, easily crystallized, solid particles or corrosive media.
Integrating the opinions of the two people above is the answer.
But the diaphragm pressure gauge I read in the book is a type of diaphragm pressure gauge.
Simply put, the most obvious difference is that the measuring element (elastic sensitive element) is different. The diaphragm meter uses the diaphragm as the measuring element, while the diaphragm meter uses the spring tube in the meter head as the measuring element. The diaphragm only plays a role in isolation and transmission rather than sensitivity. Therefore, the diaphragm meter can achieve a relatively small range, usually as low as 1kPa, and the maximum is usually 2.5MPa; while the range that the diaphragm meter can achieve is the range of the spring tube, which can usually be selected between 0.1-40MPa.
