Three-axis seat-pad vibration acceleration sensor
Overview
When a car is driving, uneven road surfaces and rotating parts such as the engine, drive train, and wheels will excite the car's vibration. In order to evaluate the comfort of occupants, NE has specially integrated several IEPE three-axis cushion vibration acceleration sensors. The products have the characteristics of high accuracy, low impedance, high signal-to-noise ratio, and low cost of supporting equipment. They are ideal for measuring vibration in the field of vehicle testing. product.
Main features:
- Easy to install and easy to use
- It can be directly connected to a data collector with a built-in constant current source
- Low noise, high level, low impedance output, strong anti-interference ability, can transmit signals through long cables without causing noise increase
