The sensor’s ability to maintain calibration stability over temperature variations and mechanical stress ensures reliable long-term performance.

Compared with higher-range units such as the 330425 model, the 330400-02-05 Accelerometer prioritizes optimal sensitivity for standard machinery acceleration monitoring, making it ideal for early anomaly detection and trending of mid-to-high frequency vibration signatures. When integrated with condition monitoring systems, proximity probes, and supervisory diagnostic software, the 330400-02-05 Accelerometer contributes to a more complete interpretation of machine health by supplying accurate acceleration data essential for identifying imbalance, looseness, bearing degradation, and gear-mesh irregularities.

With its compliance to industry standards, robust construction, and precision sensing capability, the 330400-02-05 Accelerometer stands as a trusted component for maintaining operational reliability in modern industrial facilities. It is an indispensable sensing element for any plant seeking dependable acceleration measurement and proactive equipment protection.

Applications

1. Rotating Machinery Vibration Monitoring

With its wide acceleration range of 490 m/s² (50 g) and broad frequency response from 10 Hz to 15 kHz, the 330400-02-05 accelerometer is ideal for monitoring vibration in turbines, compressors, pumps, motors, and fans. It provides accurate detection of imbalance, misalignment, looseness, and mechanical degradation.

2. Bearing Condition and Early Fault Detection

The device’s low broadband noise floor of 0.039 m/s² (0.004 g) enables precise measurement of low-amplitude vibration signals, making it particularly effective for detecting early-stage bearing wear, lubrication issues, and rolling-element defects in critical machinery.

3. High-Speed Equipment and Gearbox Diagnostics

Featuring a mounted resonant frequency greater than 30 kHz and excellent amplitude linearity, this accelerometer supports high-frequency vibration analysis required for gear mesh monitoring, high-speed spindle applications, and gearbox condition diagnostics.

4. Industrial Environments with Hazardous Area Requirements

With global safety certifications including CSA, ATEX, and IECEx, the 330400-02-05 is suitable for deployment in explosive or hazardous locations such as:

• Oil & gas refineries

• Petrochemical plants

• Offshore platforms

• Chemical processing units

• Power generation facilities

5. Structural Health and Machine Frame Monitoring

Thanks to its transverse sensitivity less than 5% and robust M8 × 1 integral stud mounting, the accelerometer ensures accurate structural vibration measurement on machine housings, frames, and support structures, assisting in mechanical integrity assessment.

Specifications

Competitive Advantage

1. High Measurement Accuracy and Stability

The 330400-02-05 accelerometer offers a sensitivity of 10.2 mV/m/s² (100 mV/g) ±5%, ensuring reliable vibration measurement across demanding industrial environments. Its amplitude linearity of ±1% up to 490 m/s² (50 g) further enhances precision, enabling consistent performance in both low and high-level vibration conditions.

2. Wide Dynamic and Frequency Range

With an acceleration range up to 490 m/s² (50 g) peak and an operating frequency span from 10 Hz to 15 kHz, this device supports broad-spectrum vibration analysis. The mounted resonant frequency exceeding 30 kHz ensures a strong response to high-frequency vibration, offering superior performance in rotating machinery monitoring.

3. Exceptional Low-Noise Performance

The accelerometer features a broadband noise floor of only 0.039 m/s² (0.004 g) rms, enabling accurate detection of low-amplitude vibration signals. This low noise characteristic enhances early fault detection for bearings, gears, and other critical components.

4. Superior Environmental and Thermal Stability

Engineered for reliability in harsh operating conditions, the unit demonstrates a temperature sensitivity of -11% to +3%, maintaining stable performance across a wide temperature range. The transverse sensitivity less than 5% minimizes measurement interference, ensuring clean and accurate vibration readings.

5. Robust Mechanical Design

The M8 × 1 integral stud mounting provides secure installation and excellent mechanical coupling, reducing the risk of resonance or installation-related errors. The 20 dB maximum resonant peak amplitude also contributes to mechanical stability and minimized distortion.
