Micro-Magic Inc. Unveils AC-6 Series High-Precision Quartz Flexure Accelerometers for Harsh Environments
In industries where accuracy, reliability and adaptability to high temperature and vibration-resistant environments are critical, the AC-6 series high-performance quartz flexure accelerometers from Micro-Magic Inc are undoubtedly a disruptive product. Designed specifically for the most challenging high temperature and vibration-resistant environments, this advanced accelerometer is an ideal choice for oil and gas drilling, geophysical exploration and other fields with its unparalleled accuracy and stability.
The AC-6 quartz flexible accelerometer product adopts unique miniaturization, high temperature and vibration resistant design, advanced packaging technology and dedicated circuit. Users can select the appropriate sampling resistor through calculation to achieve high-precision output. And according to user requirements, built-in temperature sensors are used to compensate for local values and scaling factors, reducing the impact of environmental temperature.
How does AC-6 solve the problems of stability and reliability in high temperature environments?
In order to solve the problem of low working life of the accelerometer probe under high temperature, the connection process is improved by using gold wire bonding to connect the terminal post to the gold-plated film on the quartz pendulum.
A multi-chip module thick-film hybrid integrated circuit process is adopted for the servo circuit. The substrate used is aluminum oxide ceramic and the conductor is metal gold, which solves the problem of long-term stability under high temperature and has a small error.
In the test phase, in order to meet the high-temperature working environment of petroleum logging, the accelerometer underwent high-temperature aging at 180°C for more than 96 hours to ensure long-term stability during high-temperature operation.
AC-6 also has the following significant characteristics:
Ø Both static and dynamic testing can achieve high-precision measurement, with bias stability (1σ, one month)≤150μg and resolution as low as 30μg.
Ø The measurement range reaches ±30g, meeting the acceleration measurement requirements in extreme environments. Bandwidth of 800~2500Hz, suitable for high-frequency dynamic measurement scenarios.
Ø The anti-vibration ability reaches 25G (20~2000Hz), and the anti-impact ability is 1000g (0.5ms half sine wave), ensuring stable operation under harsh conditions.
The AC-6 quartz accelerometer has become a benchmark product in the field of industrial measurement due to its high precision, high reliability, and excellent adaptability to high temperature and harsh environments. Its mature technology and wide range of applications have validated its outstanding performance. Whether it is static testing in extreme environments or high-frequency dynamic testing, AC-6 can provide users with reliable solutions.
