Impact Acceleration Sensor (IEPE) LZDY1-C

Model: LZDY1-C

1） Overview:
The universal single axis voltage type (IEPE) LZDY1-C is a miniature voltage type accelerometer independently developed by our company. All its indicators meet the requirements proposed in ISO2954-1975 and GB13824-1992. This series of acceleration sensors adopts the principle of piezoelectric effect, processed by internal amplification circuit, and powered by 2-10mA constant current source. Compared with charge amplifiers, except for the low operating temperature range, they have better anti-interference and signal distortion than charge output sensors. It has a wide frequency response, good dynamic characteristics, and strong anti-interference ability. It is widely used in vibration control, drop testing, environmental testing, structural testing, product quality research, mechanical research, modal testing and other vibration and impact dynamic testing fields.
Features:
● Large impact measurement
● Built in IEPE preamplifier
● Lightweight, high stiffness, fast response, and good temperature characteristics
Application example:
● Bulletproof vest
● Impact detection
