Pressure sensors and transducers are commonly used to measure pressure and produce an output signal that is proportional to the applied pressure. The DPH-A22 is a pressure sensor produced by GE Sensing that is specifically designed to accurately detect both positive and negative pressure changes. It is capable of detecting pressure changes as small as 5 mbar and as large as 1000 mbar.

The DPH-A22 is available in two varieties. The first is the DPH-A22-S, which is designed for high accuracy applications such as medical, pharmaceutical, and industrial. It utilizes a ceramic-based sensor element and comes with a stainless steel housing. The second is the DPH-A22-P, which is designed for low cost applications such as consumer products. It utilizes a plastic-based sensor element and comes with a plastic housing.

The DPH-A22 pressure sensor utilizes a strain-gauge bridge circuit and two integrated comparators. The strain-gauge bridge circuit is comprised of four strain gauges that are connected in a Wheatstone bridge arrangement. The bridge is designed so that the resistance changes in response to applied pressure; the resistance of the two inner gauges increases while the resistance of the two outer gauges decreases. This results in the bridge voltage changing in response to pressure change.

The bridge circuit output is then fed into two integrated comparators. The first comparator is set to detect positive pressure changes, while the second is set to detect negative pressure changes. When either of the two comparators detects a positive or negative pressure change, an internal signal is generated which is then translated into a digital output. This output is used to indicate the presence or absence of pressure.

The DPH-A22 is solid state and features a low power consumption, making it suitable for a wide variety of applications. It is compatible with both 3- and 4-wire systems, allowing it to be used in applications that require both positive and negative pressure detection. It is also vibration and shock resistant, and can be used in various temperature ranges.

The DPH-A22 is an ideal pressure sensor for applications that require both accuracy and affordability. It is capable of accurately detecting both positive and negative pressure changes, and can be used in a variety of applications. Its low power consumption and compatibility with both 3- and 4-wire systems make it a great choice for applications that require an accurate and reliable pressure sensor.
