Medium water at 100-150 degrees, pressure transmitter installed in the pipeline

This post was last edited by wx_Wang81529 on 2023-3-13 at 10:14. As the title suggests, can a regular pressure transmitter with a threaded connection be installed directly on the pipeline? (Will temperatures over 100 degrees damage the instrument?) Or should it be installed using pressure transfer tubes? If pressure transfer tubes are used, then insulation needs to be considered, right? I saw in the self-control installation manual that there is no method for installing a condensate ring on pressure transmitters; only local pressure gauges have a method for installing a condensate ring
It is recommended to use special pressure transmitters capable of withstanding high temperatures, and to install them using pressure tap pipes. The pressure tap can effectively reduce the transfer of medium temperature to the instruments, and it also helps to ensure an appropriate installation location as well as make optimal use of the pressure tap. Furthermore, due to the high temperature of the medium, it is necessary to insulate the pipes to prevent the temperature from having an adverse effect on the pipelines and the entire system. -
"I saw in the control installation manual that there is no method for installing a condensate ring on pressure transmitters; only local pressure gauges have such a condensate ring. If you want to install the pressure transmitter directly on the pipeline, this can also be considered local installation – just add a condensate ring.
You can simply choose a high-temperature pressure transmitter
At 100 degrees, we need to take into account the mixing of gas and liquid; the balance vessel is used on our boilers to measure the pressure of the steam
