Process Engineering Division – Instrumentation and Automation Section – Daily Question – Question from 2020-09-12: Discussion question: 233. What is the function of the nozzle–baffle mechanism?
Convert the displacement change of the baffle into a pneumatic pressure signal for output
By varying the distance (a slight displacement) between the nozzle and baffle mechanism, the back pressure in the back pressure chamber is altered, thereby achieving power amplification of the gas signal.
By varying the distance (a slight displacement) between the nozzle and baffle mechanism, the back pressure in the back pressure chamber is altered, thereby achieving power amplification of the gas signal.
The nozzle-baffle mechanism is a basic component used in almost all pneumatic instruments. Its function is to convert the slight displacement of the baffle into a corresponding air pressure signal as the output. It consists of three parts: a constant-throttle orifice, a backpressure chamber, a nozzle, and a baffle.

The nozzle-damper mechanism is a basic component used in almost all pneumatic instruments. Its function is to convert the slight displacement of the baffle into a corresponding air pressure signal as the output. It consists of three parts: a constant-throttle orifice, a backpressure chamber, a nozzle, and a baffle.
