Why Extreme Conditions Demand Specialized Vibration Sensors
In industries like nuclear power and petrochemical processing, equipment must operate reliably under extreme temperatures and explosive atmospheres. Standard accelerometers fail in such environments, leading to inaccurate data and costly downtime. The Vibro Meter 144-901-000-601 addresses this challenge with certified performance from -196°C to +700°C and ATEX Zone 0 approval.
This piezoelectric accelerometer delivers consistent sensitivity of 10 pC/g across a frequency range of 3 Hz to 2800 Hz. Its robust design ensures accurate loose part monitoring and structural health assessment in the harshest conditions.
Technical Specifications and Performance
The 144-901-000-601 operates with a charge output and requires no external power. Its sensitivity at 120 Hz is 10 pC/g ±5%, with a dynamic measuring range from 0.001 g to 200 g peak. Overload capacity reaches up to 500 g peak, and linearity remains within ±1% over the full range.
Transverse sensitivity is less than 5%, and mounted resonance frequency exceeds 17 kHz nominal. The frequency response is ±5% from 3 to 2800 Hz and less than 10% from 2800 to 3700 Hz. Internal insulation resistance is a minimum of 10⁹ Ω, ensuring signal integrity.
Environmental resilience includes continuous operation from -54°C to +650°C and extreme capability from -196°C to +700°C. The unit withstands shock acceleration under 500 g peak and pressure up to 140 bar at 23°C or 80 bar at 300°C. Its Inconel 600 construction provides corrosion and humidity resistance through hermetic welding.
ATEX Certification for Hazardous Areas
The 144-901-000-601 holds EC type examination certificate LCIE 08 ATEX 6017 X II 1 G, permitting use in Zones 0, 1, and 2 with gas groups IIC and temperature classes T6 to T710. This certification makes it suitable for explosive atmospheres where safety is paramount.
Installation inside a tube uses four Allen screws M6 with a fastening torque of 15 Nm. The standard version includes a 5-meter cable with Lemo connector, ensuring reliable signal transmission in demanding environments.
Real-World Application Example
In a nuclear reactor coolant pump monitoring scenario, the 144-901-000-601 provides continuous vibration data under high radiation and temperature. Its gamma flux tolerance of 10¹¹ erg/g and neutron flux tolerance of 10¹⁸ n/cm² ensure no performance degradation over time.
This accelerometer also excels in petrochemical plants where explosive gases require ATEX-rated equipment. The charge output system maintains signal quality over long cable runs, reducing the need for frequent recalibration.
