　　Pressure sensorThere are many types of threads for pressure sensors, among which the common ones are NPT, PT, G, and M, all of which are pipe threads. NPT is the abbreviation for National Pipe Thread (USA), which belongs to the 60-degree tapered pipe thread standard for American pressure sensors and is used in North America. National standards can be referenced. GB/T12716-1991 PT is the abbreviation for pipe thread, which is a 55-degree sealing tapered pipe thread. It belongs to the Whitworth pressure sensor thread series, mainly used in Europe and Commonwealth countries. It is commonly used in the water gas pipeline industry, with a taper specification of 1336016. National standard GB/T7306-2000 G is a 55-degree non-threaded sealing pipe thread, belonging to the Whitworth pressure sensor thread series. The marking G represents cylindrical threads. According to national standards, GB/T7307-2001 M is a metric standard thread. For example, M20*1.5 indicates a diameter of 20 millimeters and a pitch of 1.5. If the customer has no special requirements,Pressure sensorit is generally M20*1.5 thread. In addition, the markings 1/4, 1/2, and 1/8 on the thread refer to the diameter of the thread size, measured in inches. Industry insiders generally use points to refer to the wire diameter. 1 inch equals 8 points, 1/4 inch equals 2 points, and so on. g seems to be a general term for pipe threads, with the division between 55 degrees and 60 degrees being functional, commonly referred to as pipe circles. The thread is processed from a cylindrical surface.

ZG is commonly known as pipe taper, meaning the thread is processed from a tapered surface, which is the same as general water pipe pressure joints. The old national standard marked with Rc metric threads is expressed in pitch, while American threads are expressed in threads per inch, which is the biggest difference in pressure sensor threads. Metric threads are 60 degrees equilateral, imperial threads are 55 degrees isosceles, and American threads are 60 degrees. Metric units are used for metric threads, while imperial units are used for American and imperial threads. Pipe threads are mainly used to connect pressure pipelines, with tight fitting between internal and external threads.Pressure sensorThere are two types of pipe threads: straight pipe and tapered pipe. The nominal diameter refers to the diameter of the connected pressure pipeline. Obviously, the large diameter of the thread is greater than the nominal diameter. 1/4, 1/2, and 1/8 are the nominal diameters of imperial threads, measured in inches.
