What are Common Types in Pressure Sensor Connection Thread

There are many kinds of threads for pressure sensors. NPT, PT, G, and M are common in use and they are all pipe threads.

Thread
Interpretation
G
G is a 55 degree non-threaded sealed pipe thread, belonging to the Wyeth thread family. Marked as G, representing a cylindrical thread. G is the general name of the pipe thread, commonly called the pipe circle, that is, the thread is machined from a cylindrical surface. The division of 55 degrees and 60 degrees is a functional division.
NPT
es and 60 degrees is a functional division.
NPT    NPT is the abbreviation of National (American) Pipe Thread, which is 60 degree taper pipe thread belongs to the American standard and is commonly used in North America.
M
M is a metric ordinary thread, for example, M20*1.5 means a diameter of 20 mm and a pitch of 1.5 mm.
PT
PT is the abbreviation of Pipe Thread, which is a 55 degree sealed conical pipe thread. It belongs to the Wyeth thread family and it is used in Europe and Commonwealth countries mostly. PT is commonly used in the water and gas pipe industry, whose taper is stipulated for 1:16.
ZG
ZG is commonly called pipe cone, that is, the thread is machined from a conical surface. The general water pipe connectors are like this and its old national standard is marked as Rc.
Pressure sensor connection thread
Tips:
The 1/4, 1/2, 1/8 marks in the G and NPT threads refer to the diameter of the thread size, whose unit is inch. In the use of pressure sensors, the thread size is usually called point. One inch is equal to 8 points, 1/4 inch is equal to 2 points, and so on.
Metric threads are expressed as pitch. American threads and inch threads are expressed as the number of threads per inch. This is the biggest difference between the two. The metric thread is a 60-degree equilateral tooth, the inch thread is an isosceles 55-degree tooth, and the American thread is 60 degrees. Metric threads are used in metric units. American threads and inch threads are used in imperial units.
The pipe thread is mainly used for the pipe connection, and the inner and outer threads are closely matched. There are two kinds of straight pipe and tapered pipe. The nominal diameter refers to the diameter of the pipe to which the thread is connected. It is obvious that the diameter of the thread is larger than the nominal diameter.
ATO pressure sensors are available in G1/4, G1/2, 1/4NPT, 1/2NPT, M14*1.5, M20*1.5 thread types.
