Regarding the names of instrument piping fittings
Thread Content
I’ve only been working with instruments for a short time, and there are many names of instrument fittings that I’m not familiar with. For example, what is the name of the clamp used to attach bimetallic or PT100 sensors to pipes? Also, where are the M27*2 and M20*1.5 with inward-threaded inner ends and outward-threaded outer ends used? I would appreciate guidance from various seniors
There are too many things; it’s better to learn from a documentation system.
There are straight connectors, as well as angled connectors. The standard name in the installation manual. Both thread sizes M27X2 and M20x1.5 are available. It can be used in conjunction with temperature sensing components.
Most of the pressure gauges I’ve come across show 201.5, and most PT100 sensors read 272. I’m not sure if this is correct
Straight connectors: threads M33X2, M27X2, M12X1.5, M16X1.5, M20x1.5, G1/2", G3/4", G1"; in recent years, those with 1/2NPT threads have also been common.

1. We call pipe clamps bases, such as bimetallic bases. 2. M27*2 is often used on the connection threads of thermocouples, thermal resistors, and bimetallic elements. 3. M20*1.5 is commonly used in field pressure gauges, differential pressure transmitters, pressure transmitters, and instrument electrical interfaces; ask if you have any questions
