Product Introduction

The GKM3 series triaxial vibration sensor, developed by RUICOM Technology, is designed for vibration and impact testing. It features an analog current output, supports address code settings, and allows for series connection of multiple sensors over long distances. The sensor uses single-crystal silicon capacitive sensing technology and includes a micromachined silicon chip, a low-power ASIC signal conditioning circuit, a microprocessor for compensation data storage, and an integrated temperature sensor. It is calibrated for precision, offers low power consumption, and has a stable structure with reliable output. The electronic system includes a solid-state power supply reset design and overcurrent protection.

Application Scope

• 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

Technical Highlights

• Analog current output interface
• Vibration range: 10~2000Hz, 10g
• Shock resistance: 100g@11ms, triaxial (half-sine wave)
• Excellent mechanical strength and long-term stability

Performance Parameters

The sensor offers various measurement ranges (±2g to ±40g) with corresponding sensitivity, bias calibration, and other parameters. It operates with a 4~20mA output current and requires a 9-36 VDC input. The device is IP67 rated and comes with a 2-meter black PVC shielded cable.

Ordering and Selecting

Models are selected based on measurement range, output current, and installation method. For example, GKM302-A1-T indicates a ±2g measurement range with a 4~20mA output and standard installation.

Product Size and Installation

The sensor's shell size is L36×W32×H24mm, and it can be installed using a magnetic adsorption base. The installation requires 4 M4 screws.

PIN Definition and Acceleration Calculation

The connector has five pins for power, axis current signals, and ground. Acceleration is calculated using the formula: Acceleration = (Output Current - 12mA) ÷ Sensitivity.
