Furthermore, the PE (piezo-electric) accelerometer as it has become known, can operate over a very wide frequency range making it the most popular choice for measurement of vibration and shock, and with integration of the vibration signal it is possible to also measure velocity and even displacement if the conditions are right. Units of Measurement

This type of transducer generates an electric voltage that is proportional to acceleration, due to the pressure applied on a piezoelectric crystal.

Knock Sensors. Knock sensors (subset of accelerometers) are used to detect irregular vibrations caused by uneven cylinder combustion in engines. Piezo knock sensors are an essential component in optimizing fuel economy for internal combustion engines. Knock sensor data is direct input device to the power-train control module that can then

CA280 piezoelectric accelerometer. Designed for the long-term measurement of vibration in extreme environments, such as gas turbines, gearboxes and compressors. Operating temperature: −60 to 260 °C. Frequency response: 0.5 to 6000 Hz. Available as a sensor only (no integral cable) or with an integral soft-line cable with a flexible stainless
