Problems with bimetal thermometers and resistance protection tubes
Thread Content
The connectors we soldered at the oil station that were used to measure the oil temperature resistance have been replaced with connectors for bimetal thermometers. They are all M27.* 2. But the resistor protection tube is too big, and the thread is also a lot longer. I would like to ask, what is a good way to deal with it if the joint is not replaced?
Remove the bimetal core and use the bimetal sleeve to replace it with a thermal resistance core.
There is an M27x2 movable joint, which is threaded on the thermometer sleeve. After tightening, the sleeve is locked.
Change the connector to avoid affecting the measurement accuracy.
Is the pressure high? If not, just use the armored core to measure it and add a movable ferrule thread seal.
It seems that we should cut off the bimetal joint and re-weld a thermal resistor straight connector. However, the oil in the gas station must be drained to avoid fire.
