Thread pressure sensor There are many common are NPT, PT, G, M, all pipe threads. NPT is National (American) Pipe Thread acronym, belong to US pressure sensor standard 60-degree taper pipe threads for North America. National standards can be found GB / T12716-1991 PT is the abbreviation Pipe Thread pressure sensor manufacturer, is 55 degree seal tapered pipe thread, is a Whitworth thread family pressure sensors, used in Europe and the Commonwealth countries. Commonly used in water and gas pipe industry, taper 1:16 regulations. National standards can be found GB / T7306-2000 G is 55 degrees non-threaded pipe thread sealing pressure sensors offer, is a Whitworth thread pressure sensor family. Labeled G for threaded barrel. National standards can be found GB / T7307-2001 M metric common thread, such as M20 * 1.5 represents a diameter of 20mm, pitch of 1.5, such as the customer no special requirements, the pressure sensor is generally M20 * 1.5 thread. Pressure is an important parameter in industrial production, in order to ensure the normal operation of the production of pressure sensors, pressure must be monitored and controlled. Below is a selection of commonly used terms pressure sensor: standard size in the atmospheric-pressure standard representation, called positive pressure greater than atmospheric pressure; less than atmospheric pressure is called negative. Absolute pressure with pressure for a standard size represents an absolute vacuum. Comparison of the relative pressure of the object (standard pressure) in terms of pressure. Refers to the atmospheric pressure atmospheric pressure. Standard atmospheric pressure (1atm) equivalent to the height of the pressure of 760mm Hg. Vacuum means below atmospheric pressure. 1Torr = 1/760 Pressure (atm). Pressure range is adapted to detect the pressure range of the sensor. When can withstand the pressure when restored to detect pressure, its performance does not drop may be under pressure. When the accuracy of the pressure fluctuation values ??and from a certain temperature (23 ° C) lower, while increasing, decreasing pressure, with the full-scale value of the detected pressure to remove inverted output pressure value obtained by the operation point.
