PEA series
Outline
The PEA series WACOH-TECH is a 3-axis acceleration sensor using piezoceramic for the detection element. With respect to acceleration A applied from all directions to the sensor, acceleration components (Ax, Ay, Az) in 3-axis directions are output.
From these signals, the magnitude and direction of acceleration can be obtained.
The sensor is structurally designed so that acceleration in the 3-axis directions can be simultaneously detected by one element. This has realized a compact, lightweight, and low-priced sensor. Also, it is remarkably easy to handle because the output is made by an operational amplifier.
It can be used in across wide range of industrial fields, such as vehicles, robots, machine tools, and games.
Applications
- Vehicles
Airbag system/vibration measurement and control/chassis control
- Robots and machine tools
Abnormal vibration detection/arm control
- Consumer products
Pedometers/inputs devices for games/seismometers (seismoscopes)/crime preventive vibration sensors
Features
Simultaneous detection of acceleration on three axes:
Acceleration A is output as separated into acceleration components (Ax, Ay, Az) in 3-axis directions.
|
|
Compact and lightweight:
Compact and lightweight as acceleration on three axes can be detected by one element.
|
|
Wide dynamic range:
Stable measurement can be made in the frequency ranges of 0.5 – 500 (PEA304), 1000 (PEA320), and 2000Hz (PEA350).
