An Air pressure transducer is a sensor that converts the mechanical signal of air pressure into a current signal. Pressure has a linear relationship with voltage or current, and it is generally proportional. Therefore, the output voltage or current of the transmitter increases as the pressure increases. From this, a relationship between pressure and voltage or current is derived.
The functional principle of a resistive pressure transmitter is very simple. The pressure sensor converts the mechanical pressure value into a proportional electrical signal. The pressure sensor typically consists of a stable main body and a (thin) diaphragm.
The diaphragm is the most important element for the measurement of the pressure and is equipped with strain-sensitive and compression-sensitive resistance structures, so-called strain gauges (DMS). The diaphragm is deflected under the influence of pressure.
Thus, the strain gauges attached to it are elongated or compressed and its electrical resistance changes. This change in resistance is directly proportional to the pressure. For example, if the resistors are wired to a Wheatstone measuring bridge, the resulting electrical signal can be measured and transferred to an indicator.
There are different types of pressure transducers based on their design.
These sensors can come in several shapes and sizes, but the technology inside can also differ.
There 4 main types of pressure sensor based on this:
