QZ2012-A vibration sensor Introduction: The QZ2012-A series speed sensor is a high-quality sensor with independent intellectual property rights jointly developed by the Institute of Engineering Mechanics of China Earthquake Administration and our company. The sensor adopts the principle of differential magnetic steel induction vibration and uses passive closed-loop servo technology, which has good low-frequency characteristics and impedance matching characteristics. This series of speed pickups is a multifunctional vibration speedometer used for low-frequency vibration measurement, which can measure micro speed, medium speed, and high speed signals. This sensor can be used in conjunction with our G01NET series data acquisition instrument, as well as with other voltage signal acquisition instruments. Mainly used for measuring site pulsation (micro vibration) and blasting vibration; Measurement or monitoring of pulsations, wind-induced vibrations, and earthquakes in high-rise buildings such as buildings; Measurement of ultra-low frequency pulsation (micro vibration) and large vibration of large-span structures such as bridges. characteristic: 1. High reliability and long service life. 2. High resolution. 3. High sensitivity. 4. Wide measurement range. 5. High waterproof rating. Technical parameters: Model: QZ2012-A (for passive blasting) Effective frequency band range (Hz): 4.5~3000 Sensitivity (V.S/m): 100 Output impedance (K Ω): 3.8 Resolution (m/s): 2x10-8 Maximum range (m/s, 0-p): 0.05 Dimensions (L * W * H): Unidirectional: 40 * 40 * 78mm; Three directions: 200 * 144 * 80mm Usage environment: Temperature: -35 ℃~+70 ℃
