Connecting volume effects on dynamics of pneumatic pressure measurement systems

J. Kutin, A. Svete


The pressure sensors are often placed at a certain distance from the measured object. Beside the properties of the transmission fluid, dynamic characteristics of such a measurement system depends on the geometry and dimensions of the connecting elements. So far made research works have shown that the internal volume of the pressure sensor can have a large influence on the dynamic response. This paper is focused on theoretical analysis of the effects of the sensor volume on characteristic parameters of both the frequency and the time response of the system under discussion with a gas medium.
