Accelerometers |Force Sensors| Pressure Sensors | Microphones Pressure Sensors and Transmitters PCB® offers a wide variety of pressure sensors to satisfy a multitude of dynamic and static pressure measurement requirements. Piezoelectric, strain gage, thin film, and piezoresistive sensing technologies are offered. Whether it’s a pharmaceutical injection design application, an explosives test, or a combustion instability study of a rocket motor, we can help with sensors, that are off-the-shelf or custom designed for the specific application. Differences between static and dynamic pressure sensors. Static pressure sensors most often use strain gage, piezoresistive, or capacitive sensing technologies. Such devices are capable of measuring slowly changing or static pressures and are ideal for many process monitoring requirements. Although some specialty silicon based sensors can achieve higher frequencies and faster rise times, most static pressure sensors have a response limited to about 1000 Hz and a respective 1 msec rise time. Potentially damaging pressure changes that occur faster than this can be missed by these sensors. Dynamic pressure sensors are characterized by their ability to respond within microseconds and achieve frequencies well beyond 100k Hz. They most often use piezoelectric quartz sensing technology, however, other piezoelectric crystals may be used depending upon the application. Since piezoelectric sensors are AC coupled devices, they do not measure static pressure. This property provides these sensors with the unique ability to monitor low level dynamic pressures while being subjected to a high static background pressure level. Piezoelectric pressure sensors have no moving parts, are rigid, linear, durable, and extremely repeatable. They can withstand high static loads, yet accurately respond to small pressure fluctuations.
