Looking for manufacturers of indoor pressure control devices
Thread Content
To increase the budget for HVAC systems, it is necessary to install pressure sensors indoors; the equipment should be activated when negative pressure is detected. Generally, the instruments used are those installed on the equipment and pipes, but it’s not clear what kinds of instruments are available inside the rooms
You can buy a regular pressure transmitter with a display, with a range of plus and minus 10 KPa; brands from lower-tier manufacturers will cost around two to three hundred yuan, and it’s possible to measure indoor pressure using an open-type model. Atmospheric pressure sensors can also be purchased; they cost around 200 to 300 yuan. Some of them come with integrated temperature and humidity sensors, and they support 485 communication; analog output can also be customized.
