Pressure transmitter on the air duct
Thread Content
To measure the pressure in air ducts, with a maximum pressure of 700 Pa, what type of pressure transmitter is suitable?
Choose the micro-pressure one; there are more of those. .

Micro-differential pressure transmitters, used in HVAC systems, are available from a variety of brands. Like Dywer and things like that.
A transmitter with differential pressure measurement should work; the EJA120E series would be suitable
There are countless of them; this problem is really easy.
The question posed by the original poster is a bit too broad; anything that can measure pressure will do, and the key is to choose one with good cost-performance ratio.
The requirements aren’t high; just pick any one. Many domestic ones are used for duct measurement. For higher requirements, EJA120 and so on
