Is the thermometer connector M27X2?
Thread Content
The thermocouple thermometer connectors and bimetal thermometer connectors designed by our institute are all M27X2. I would like to ask, is the connector form of M27X2 the most common and versatile?
The joint forms of thermocouple thermometer joints and bimetal thermometer joints are M27X2, which is the most common threaded joint method. One of the meter heads is in the form of an external thread, and the side with the pipe or equipment is a straight-through connection (internal thread form). The two are connected together. For thermometers, there is another connection method that is a flange connection. For pipes smaller than DN40, a temperature expansion pipe is used to connect, and the flange is connected to the thermometer.
There seems to be another kind of M33X2, one end is internally threaded, and the other end is blocked. Have you seen it? It would be best if you can send a copy of the drawing.
The common one is m27* 2 and flange connection
