Temperature sensors are the most widely used in our daily life and industry. andtemperature sensorThe threads on it can help with its application, reduce errors, and provide work efficiency. andtemperature sensorThere are many types of threads, including NPT, PT, G, and M threads.

NPT is the abbreviation for National (American) PipeThread, which belongs to the 60 degree taper pipe thread of the American pressure sensor standard and is used in North America. The national standard can be found in GB/T12716-1991.

PT stands for PipeThread, a 55 degree sealed conical pipe thread belonging to the Wyeth pressure sensor thread family, commonly used in Europe and Commonwealth countries. Commonly used in the water and gas pipe industry, the taper is specified as 1:16. The national standard can be found in GB/17306-2000

G is a 55 degree non threaded sealed pipe thread, belonging to the Wyeth pressure sensor thread family. The symbol G represents cylindrical thread. The national standard can be found in GB/T7307-2001.

M is a metric ordinary thread, such as M20 * indicating a diameter of 20mm.

In addition, the 1/4, 1/2, and 1/8 markings in the thread refer to the diameter of the thread gauge, measured in inches. Insiders usually refer to thread size in minutes, with one inch equal to 8 minutes, 1/4 inch equal to 2 minutes, and so on. G seems to be the general term for pipe threads (Guan), and the 55 and 60 degree divisions are functional, commonly known as pipe circles. The thread is machined from a cylindrical surface.

ZG, commonly known as pipe cone, refers to a thread that is machined from a conical surface. This is how most water pipe pressure joints are made, and the old national standard is labeled as Rc

Metric threads are represented by pitch, while American and British threads are represented by the number of threads per inchtemperature sensorThe biggest difference between threads is that metric threads have a 60 degree equilateral profile, imperial threads have an isosceles 55 degree profile, and American threads have a 60 degree profile. Metric threads are measured in metric units, while American and British threads are measured in imperial units.

The management pattern is mainly used for connecting pressure pipelines, and its internal and external threads are tightly matched,temperature sensorThere are two types of pipe threads: straight pipe and push pipe. The nominal diameter refers to the diameter of the pressure pipeline connected, and obviously the larger diameter of the thread is larger than the nominal diameter. 1/4, 1/2, 1/8 are the nominal diameters of imperial threads, measured in inches.
