Three Axis Vibration Sensor
Product Introduction
The VS-1000SLFP series is a three-axis accelerometer tailored for NVH testing and impact dynamic measurement. It's an IEPE accelerometer with an internal charge amplifier, utilizing a coaxial cable for both power supply and signal output. This design allows for a constant current supply of 2-10mA to the sensor, ensuring accurate measurements.
The accelerometer's shear mode sensor element, made from stable piezoelectric ceramic, offers long-term stability and repeatability. This element's characteristics, including low transverse sensitivity and resistance to base deformation and thermal transients, minimize interference, enhance reliability, and simplify testing.
The VS-1000SLFP accelerometer boasts a titanium alloy housing, providing a compact size and lightweight design. Its unique structural design ensures a broader operating temperature range and frequency response, making it suitable for various applications.
Product Parameters
The product parameters meet the international standards, ensuring excellent performance.
