Accelerometers measure the acceleration or vibration of a device or system. Physically, the accelerometer can be considered a weight on a spring which is connected to a frame. When the frame is moved, the mass will stay at rest until the spring, being stretched, can exert enough energy to move the mass. The two basic types of accelerometers are piezoelectric (AC response) and MEMS based (DC response) accelerometers.
Voltage mode piezoelectric is the most popular accelerometer design due to its high level output and wide bandwidth. We offer voltage mode accelerometers in the traditional 3-wire or 2-wire (IEPE) configurations.
Charge-mode piezoelectric accelerometers measure shock and vibration in high temperature environments. In addition to its high temperature operating capability when used with a high quality charge amplifier, a charge mode accelerometer offers dynamic range scalability.
To measure velocity or displacement motion accurately, an accelerometer with DC response is required. Incorporating MEMS technologies and the latest analog and digital ASICs, our DC accelerometers offer high performance and exceptional value. All products are EAR99 and RoHS compliant.
