Upper Computer Software Video:
The GKM392 triaxial Vibration sensor is an independently developed Vibration sensor sensor series by RUICOM Technology, suitable for applications such as vibration testing and impact testing. This product supports digital interface output (RS232/485/TTL optional) and can achieve long-distance series connection of multiple sensors via address code settings, facilitating multi-point synchronous measurement and centralized data analysis.
The GKM392 adopts single-crystal silicon capacitive sensing technology. Its core components include: a micromachined silicon chip, a low-power ASIC signal conditioning circuit, a microprocessor for storing compensation data, and an integrated temperature sensor.
The product has undergone precise calibration and features low power consumption, high structural strength, and stable output. Its electronic system adopts a solid-state power supply reset design and is equipped with overcurrent protection to ensure safe and reliable operation.
The sensor exhibits long-term stability of the scaling factor and a typical deviation value better than 0.1% across the entire measurement range, meeting the requirements for high-precision measurement.
Technical Characteristics
❖ RS232/485/TTL signal output selectable;
❖ Vibration: 10~2000Hz, 10g;
❖ Shock: 100g@11ms, triaxial (half-sine wave);
❖ Excellent mechanical strength and long-term stability.
Application Field
❖ Flight data recording and analysis ❖ Structural fatigue monitoring and life prediction
❖ Bridge structural health monitoring ❖ Track vibration and roadbed stability monitoring
❖ Vehicle vibration testing and monitoring ❖ High-speed train operation status monitoring
❖ Wind turbine generator vibration monitoring ❖ Vibration fault early warning for large machinery
❖ Monitoring of heavy equipment such as road rollers
