oil pressure sensor thread size
We usually see that there are many kinds of threads for pressure sensors, including NPT, PT, G and M, which are pipe threads. Here are some common thread types of downforce sensor.
Among them, NPT is the abbreviation of National (American) PipeThread, which belongs to the 60 degree taper pipe thread of the American pressure sensor standard and is generally used in North America. The national standard can be referred to GB/T12716-1991.PT is the abbreviation of PipeThread. It is a 55 degree sealed tapered pipe thread. It belongs to the Wyeth pressure sensor thread family and is mostly used in Europe and the Commonwealth countries. It is commonly used in the water and gas pipe industry, and the taper is specified as 1:16. The national standard can refer to GB/T7306-2000.G is a 55 degree non thread sealing pipe thread, belonging to the Wyeth pressure sensor thread family. The mark G represents cylindrical screw. Refer to GB/T7307-2001 for national standards. M is a metric common thread. For example, M20 * indicates that the thread pitch diameter is 20mm. If there is no special requirement, the pressure sensor produced is generally M20 * thread.In addition, the 1/4, 1/2 and 1/8 marks in the thread refer to the diameter of the thread size, in inches. Professionals usually call the thread size by "minute". One inch is equal to 8 points, and 1/4 inch is 2 points, and so on. G seems to be the general name of pipe thread (Guan). The division of 55 and 60 degrees belongs to functional, commonly known as pipe circle. The thread is machined from a cylindrical surface. ZG is often referred to as a pipe taper, that is, the thread is machined from a taper surface. This is the case with ordinary water pipe pressure fittings. Old national standard marked as RC. Metric threads are represented by pitch, while American and British threads are represented by the number of threads per inch.
This is the biggest difference between the pressure sensor threads. Metric threads are 60 degrees equilateral, British threads are 55 degrees isosceles, and American threads are 60 degrees. Metric units are used for metric threads, and English units are used for American and British threads.Pipe threads are mainly used to connect pressure pipes. The internal and external threads are closely matched. There are two types of pipe threads for pressure sensors: straight pipe and tapered pipe. The nominal diameter refers to the diameter of the connected pressure pipe. Obviously, the major diameter of the thread is larger than the nominal diameter. 1/4, 1/2, 1/8 are the nominal diameters of inch threads, in inches.
