PWM Inclinometer

Product info

PWM inclinometer is based on Vigor patent tilt measurement technology and combined with PWM module with high anti-jamming capability.
It is designed for harsh industrial environments, ensuring critical null repeatability and delivering high combined accuracy for precise data at any angle point.

It directly drives a hydraulic proportional valve with 1A current and can also offer an integrated system including sensor, control, and driving modules to operate multiple hydraulic proportional valves, achieving automatic leveling efficiently and easily.

PWM inclinometer adopts the PWM pulse width modulation output interface, providing a linear proportional relationship between the tilt values and the duty cycle of the PWM wave, ensuring strong anti-interference ability.

• ±0.02%FS linearity
• ±0.005° Offset
• Combine with gyro module to realize static/dynamic angle measuring for low/rapid leveling
• Combine with vibration module for real-time FFT computations; directly outputs vibration frequency and amplitude data while eliminating environmental vibration effects
• Further confirmation of offset, repeatability, hysteresis, and turn-on repeatability as key factors influencing total performance evaluation
• Advanced intelligent algorithms drastically reduce cross-axis error, enhancing real tilt angle measuring accuracy
• Significantly reduced measuring errors when real tilt direction differs from the sensor’s sensitive axis
• Equipped with short-circuit, transient voltage, and transposition protection for industrial environments

The user can set all unit parameters via the RS232 interface — including zero point, baud rate, local gravitational acceleration value, zero calibration, vibration suppression filter coefficients, ID address, refresh rate, and factory data queries.

Ordering

For example, if ordering a dual-axis PWM inclinometer with range ±15°, room temperature accuracy ±0.02°, -20~60℃ total drift accuracy ±0.02°, 2-meter cable with plug, and X/Y-axis gyro,
the model should be chosen as: SST302-15-G16-F4-00-C1-D3 (2m).
