Product catalog summary
Introduction
The BW-IMU600 is a high-precision inertial measurement unit (IMU) developed by Bewis Sensing Technology. It is designed for applications such as pipeline survey engineering, construction machinery, and stable platforms. The unit outputs acceleration and angular velocity data without external signal input, suitable for various conditions including motion, vibration, or static states.

Features
The BW-IMU600 utilizes MEMS accelerometers and gyroscopes, with data accuracy enhanced by a 6-state Kalman filter. It includes compensations for nonlinearity, quadrature, temperature, and drift, improving measurement precision. Key features include:
  • Quadrature compensation
  • Gyro range: ±500°/s
  • Accelerometer range: ±60g
  • RS422 interface output
  • Operating temperature: -40℃ to +85℃
  • Compact dimensions: 44.8 x 38.6 x 24.8 mm

Specifications
Electrical Index:
  • Power Supply: 5V DC
  • Operating current: 200mA
Gyro:
  • Resolution: 0.0001°/sec
  • Bias stability: <2°/h at room temperature
Accelerometer:
  • Resolution: 0.1 mg
  • Bias stability: <1mg over full temperature range

Mechanical Characteristics
The unit is housed in a magnesium alloy shell with IP65 protection. It is installed using three M4 screws, ensuring a stable and accurate measurement setup.

Installation Guidelines
Proper installation is crucial to avoid measurement errors. The sensor should be mounted flush with the measured surface, avoiding any angles. The sensor's bottom line should be parallel or orthogonal to the measured object's axis.

Standards and Certifications
The BW-IMU600 complies with several standards, including ISO9001:2008, CE, ROHS, and various GJB and GB/T standards for reliability, environmental testing, and electromagnetic immunity.
