Pressure sensors and transducers provide the measurement of external pressure acting on a system. They are usually used to measure an absolute pressure within some range and this can be extended with the use of a barometer. One of the most common variants of pressure measurement is the PE-20E, which is often used in industrial and automotive applications.

The PE-20E is an integrated type of pressure sensor. It is capable of measuring absolute pressure and differentiating a \'Vacuum\' pressure from an \'Atmospheric\' pressure. It works by providing a constant electric current over two electrodes as opposed to three as found on strain gauge type sensors. This electric current is modulated by the external pressure level and this modulated current is then converted into a control signal by an external amplifier.

The PE-20E sensor is one of the most suitable products for design in to pressure measuring systems. This is because it is a compact, oil-free device and is able to operate with a very low power consumption level. It is also easy to install and calibrate within a system. The PE-20E has a wide operational pressure range and is designed to operate over temperatures between - 40°C and 150°C.

The core element of the PE-20E is its output system which is based upon a Wheatstone bridge. This system is made up of a set of four parallel resistors and a capacitor. Two of the resistors form the transducer bridge while the other two resistors form a reference bridge which is used to nullify the ground effect of the transducer. The capacitor is used to modify the total bridge capacitance which is then converted using anoperational amplifier. This produces a control voltage that is proportional to the pressure exerted.

In operation, the PE-20E is connected to its power and ground source and a pressure signal is applied to the bridge. As the pressure is increased, it deforms the diaphragm which acts upon the bridge. Both the reference and transducer bridge inputs are effected by the pressure signal as a result of the sense-membrane effect. This causes changes in the bridge capacitance which is then converted to a control voltage that is proportional to the applied pressure.

The PE-20E is a reliable and accurate type of pressure sensor and is widely used in applications such as oil and gas, HVAC, vehicle and aircraft instrumentation, and medical monitoring systems. It can be used in either a stand-alone unit or within an automated control system. Additionally, it can be used to measure pressure in both a vacuum and an atmosphere and it performs well in both high and low pressure applications.

In conclusion, the PE-20E is a compact, pressure-transducer that is most suitable for use in industrial and automotive applications. It works by providing a constant electric current over two electrodes and this electric current is modulated according to the pressure level. The output system is based upon a Wheatstone bridge and the capacitance of this bridge is converted into a control voltage that is proportional to the externally-applied pressure. The PE-20E is a reliable and accurate device and is used in numerous applications across a range of industries.
