Quartz flexible accelerometer: Product name: & quot;smart asteroid& quot; quartz flexible accelerometerFocus on attitude solutions and skill in direction control.Main technical parameters:
?Working temperature: 185℃
?Monthly reliability: temperature shift＜1mg
?Resolution: 1×10-5gThe & quot;smart asteroid& quot; quartz flexible accelerometer is a single-axis torque reaction type accelerometer to detect the external acceleration signal by detecting quality and then demodulated and amplified by the servo circuit, and finally output current signal proportional to the acceleration signal. This product is widely applied for high accuracy navigation systems of aerospace, oilfield drilling or strapdown system of geological exploration.Product features: High temperature resistanceVibration and shock resistanceSmall volume and light weightWide voltage power supply and low power consumptionAnalogue electronics signal outputFlange mounting or round built-in mountingProduct applications: Oil drillingInertial navigation systemPerformance parameters:Input range:±30gThreshold and resolution:1*10-5Bias(K0)＜10mgBias(K0) temperature shift＜30μg/℃Scale factor(K1)1.45Ma/g±5%Scale factor(K1) temperature shift＜300ppm/℃160℃, reliability＜1mg185℃, reliability＜1.5mgMisalignment angle＜5mradSecond order nonlinear(K2)＜100μg/g2Bandwidth＜200HzElectric performanceWorking voltage±（10-18）VDCInsulation resistance50MΩ@50VDCEnvironment conditionsSine vibration30g 0~peak,(30~2000)HzRandom vibration20gram, (15~500)HzShock1000g, 0.5msec, half shineWorking temperature(-40~185)℃Company introduction: At present, the company has been awarded with 27 authorized utility model patents and one accepted patent for invention;Won the first prize in Qingdao area and the third prize in national finals in the second session of China Innovation and Entrepreneurship Competition in November 2013;Passed through high-tech enterprise certification in 2014;Won the Second ?prize in & acute;Directional Sensor Project’ in National High-tech Industrial Zo
