Quick Detail

Description

The 330400-01-05 Accelerometer is a high-performance piezoelectric sensor engineered specifically for the demanding requirements of industrial vibration monitoring. As a primary solution within the 330400-01-05 Accelerometer lineup, this transducer is intended for critical machinery applications where precise casing acceleration measurements are essential for asset protection. The 330400-01-05 Accelerometer is meticulously designed to address and exceed the rigorous requirements of the American Petroleum Institute (API) Standard 670, making the 330400-01-05 Accelerometer the industry benchmark for safety-critical installations in the oil, gas, and power generation sectors.

Functionally, the 330400-01-05 Accelerometer provides a robust amplitude range of 50 g peak and a standardized sensitivity of 100 mV/g. This sensitivity level allows the 330400-01-05 Accelerometer to capture high-frequency signals with exceptional clarity, which is vital for specialized tasks such as gear mesh monitoring and early-stage rolling element bearing fault detection. While the 330425 variant is available for higher-intensity shocks (75 g), the 330400-01-05 Accelerometer remains the preferred choice for general-purpose high-frequency vibration analysis due to its superior signal-to-noise ratio at the 100 mV/g scale.

Applications

1.Gear Mesh and High-Frequency Fault Detection

The primary application for the 330400-01-05 is the monitoring of gearboxes and high-speed gear sets. Because faults like gear pitting, cracked teeth, or misalignment manifest as high-frequency vibration, the sensor's wide frequency span of 10 Hz to 15 kHz is essential. It allows maintenance teams to capture gear mesh frequencies and their harmonics, which are often far beyond the range of standard velocity sensors.

2.Rolling Element Bearing (REB) Monitoring

This accelerometer is widely applied to monitor machines equipped with ball or roller bearings. It detects the high-frequency "ringing" caused by early-stage bearing defects (such as flaking or spalling on the races). By utilizing the 100 mV/g sensitivity, the sensor provides the high-resolution signal required for advanced diagnostic techniques like Enveloping or PeakVue, allowing for bearing replacement before catastrophic failure occurs.

3.Aerodynamic and Flow-Induced Vibration Analysis

In centrifugal compressors, pumps, and fans, the 330400-01-05 is used to detect aerodynamic instabilities. This includes monitoring for blade pass frequencies, surge conditions, and cavitation. The sensor’s ability to handle up to 50 g peak acceleration ensures that it can monitor the high-energy flow-induced vibrations common in high-pressure turbomachinery without signal saturation.

Specifications

Competitive Advantage

1. Superior Signal Headroom for High-Energy Shocks

The primary competitive advantage of this specific 25 mV/g configuration is its expanded 740 m/s² (75 g) peak acceleration range. Most standard industrial accelerometers saturate at 50 g; however, this model provides additional "headroom." This is critical when monitoring equipment that generates high-amplitude impulsive forces, such as reciprocating compressors or complex gearboxes, ensuring the signal does not "clip" during extreme vibration events.

2. Precision Frequency Response (10 Hz to 15 kHz)

The 330400-01-05 maintains exceptional Amplitude Linearity of ±1% across a broad frequency spectrum. This high-frequency capability is essential for competitive diagnostic analysis. It allows for the early detection of gear teeth pitting and rolling element bearing defects that manifest at ultrasonic frequencies, long before they would be visible on a standard velocity sensor.

3. "Triple Crown" Global Certification

Equipped with the -05 Multiple Approvals option, this sensor is certified by CSA, ATEX, and IECEx. This provides a massive logistical advantage for global enterprises. A single part number can be specified for projects across North America, Europe, and Asia, ensuring compliance with local hazardous area regulations (Zone 0, 1, or 2) without the need for region-specific hardware.

4. Extreme Durability and Shock Survivability

With a Shock Survivability of 5,000 g peak, this accelerometer is built for survival in the "war zone" of heavy industry. The 316L stainless steel housing is hermetically sealed, protecting the delicate piezoelectric crystals from corrosive chemicals, moisture, and oil. This ruggedness ensures a lower Total Cost of Ownership (TCO) by reducing the frequency of sensor failures in high-impact applications like reciprocating engine cylinders.
