Quick Detail

Description

The 330425-02-00 Accelerometer is a high-performance industrial sensor designed for critical machinery monitoring, providing precise measurements of casing acceleration in demanding automation and predictive maintenance applications. Engineered to meet API 670 standards, this sensor delivers a sensitivity of 25 mV/g ±5% and an acceleration range of 75 g peak, capturing dynamic vibrations across a broad frequency range of 10 Hz to 15 kHz. Constructed from 316L stainless steel and equipped with an M8 x 1 integral stud, the accelerometer supports mounting in any orientation while withstanding extreme conditions, including temperatures from -55°C to +121°C and shocks up to 49,050 m/s² (5000 g). The sensor maintains signal integrity over cable lengths up to 305 meters (1000 ft), making it suitable for large industrial installations. Its low broadband noise floor of 0.098 m/s² (0.01 g) rms ensures accurate detection of subtle machinery vibrations, enabling predictive diagnostics, condition-based maintenance, and detailed operational analysis of rotating equipment, gear mesh assemblies, turbines, and pumps. The 330425 provides enhanced amplitude and sensitivity over the standard 330400 model, making it ideal for high-acceleration machinery requiring precise monitoring.

Applications

1. Gear Mesh Vibration Monitoring
Monitors gear casing acceleration to detect misalignment, wear, or tooth damage, ensuring optimal gear performance and reducing unscheduled downtime.

2. Turbine and Compressor Diagnostics
Measures high-frequency vibrations on turbine and compressor casings, enabling engineers to assess rotor balance, bearing condition, and operational stability.

3. Pump and Motor Condition Monitoring
Provides early warning of abnormal casing acceleration in pumps and motors, helping prevent mechanical failures and costly repairs.

4. Rotating Machinery Predictive Maintenance
Captures dynamic acceleration signals from industrial machinery to feed predictive maintenance software, extending equipment life and improving reliability.

5. Structural Health and Shock Analysis
Records extreme shock events up to 5000 g, allowing analysis of structural impacts on machinery, protecting sensitive components in critical processes.

Specifications

Competitive Advantage

1. High Amplitude Range
Handles up to 75 g peak acceleration, exceeding many industrial accelerometers, making it suitable for high-energy vibration environments.

2. Broad Frequency Response
Accurately measures vibrations from 10 Hz to 15 kHz, enabling detection of both slow and high-speed mechanical events in rotating equipment.

3. Rugged and Corrosion-Resistant Construction
316L stainless steel housing allows long-term reliability in harsh environments, including high temperatures and chemical exposure.

4. Long-Distance Signal Integrity
Maintains accurate readings over 305 meters (1000 ft) of cable, facilitating installation in large-scale industrial plants without signal degradation.

5. Low Noise and High Sensitivity
With a noise floor of 0.098 m/s² (0.01 g) rms and a sensitivity of 25 mV/g, the accelerometer reliably detects subtle vibrations essential for condition monitoring and early fault detection.
