Voltage Output

Kyowa voltage-output accelerometers are sensors that produce an analog electrical voltage proportional to acceleration, allowing direct measurement of vibration and dynamic motion without needing external bridge excitation or specialised conditioning hardware beyond standard voltage-measuring data acquisition systems. Many models in the Kyowa lineup output voltage directly or via built-in amplification, giving engineers clear, real-time data for dynamic testing.

📌 Key Characteristics

• Direct voltage output: These accelerometers generate a measurable voltage that corresponds to acceleration, simplifying connection to standard data loggers, oscilloscopes, or DAQ systems.

• Wide dynamic range: Available in versions covering small vibration to high-impact acceleration levels, making them suitable for general vibration analysis and harsh test environments like crash testing.

• Built-in amplifier (IEPE): Many Kyowa models include internal signal conditioning so the sensor outputs a conditioned voltage waveform directly, reducing the need for external amplifiers.

• Frequency bandwidth: Designed to capture both low-frequency vibration and high-frequency shock events with good fidelity, depending on model.

⭐ Advantages

• Simplified integration: Voltage output is easy to interface with common measurement equipment, reducing system complexity and cost.

• Real-time monitoring: Continuous analog voltage lets users see dynamic changes in acceleration live as tests run.

• Flexible applications: Works well for a range of tests from machinery vibration to automotive crash data acquisition.

• Compact and robust: Many are small and rugged, suitable for tight spaces and demanding environments.

🧪 Typical Uses

• Automotive crash and dynamic testing: Voltage output allows high-speed recording of acceleration events during impact tests for safety analysis.

• Vibration monitoring: For machinery diagnostics, modal analysis, and structural testing.

• General dynamic measurement: Any application where acceleration needs to be quantified as an electrical signal for analysis or control.
