High-Precision Quartz Accelerometers

TKD quartz accelerometers cover two main types: quartz vibrating beam accelerometers and quartz pendulous accelerometers. The vibrating beam type leverages the piezoelectric properties of quartz to detect acceleration via resonant frequency variation, offering compact size, low cost, and high reliability. The pendulous type employs a quartz flexure pendulum and force-balanced servo principle to achieve micro-g (μg) level precision measurement, featuring extremely low bias drift and excellent long-term stability. Widely deployed in inertial navigation, aerospace, precision instrumentation, and other high-end applications.

Different Types of TKD Quartz Accelerometers

Quartz Vibrating Beam Accelerometers

TKD's quartz vibrating beam accelerometers are fabricated using quartz MEMS technology, delivering a frequency output proportional to acceleration that can be directly interfaced with digital signal processing systems without A/D conversion. The device features a compact footprint of ≤12×12×4mm³, bandwidth ≥400Hz, and a measurement range of ±70g. Based on the quartz vibrating beam resonance principle, it offers high precision and excellent stability, making it ideal for high-accuracy applications such as inertial navigation and seismic detection.

Quartz Pendulous Accelerometers

TKD's quartz pendulous accelerometer features a quartz pendulous structure, with a compact footprint of <12×12×4mm³, bandwidth >800Hz, and a measurement range of ±30g. Key advantages include high resolution, low noise, and wide dynamic range, making it ideal for high-end applications such as aerospace and precision measurement.
