Is Your Monitoring System Ready for the Harshest Environments?
When vibration monitoring fails in extreme heat or cryogenic cold, unplanned downtime follows. The Vibro Meter 144-901-000-212 piezoelectric accelerometer solves this with a 10 pC/g charge output and an operational range from -196°C to +700°C. This loose-part monitoring accelerometer delivers proven reliability for oil, gas, and industrial automation applications where standard sensors simply cannot survive.
What Makes the 144-901-000-212 Different?
This Vibro Meter accelerometer is a 2-pole system insulated from its casing, providing a charge output that feeds a charge converter. It requires no input power, simplifying installation in remote or hazardous locations. The integral case insulation and hermetically welded Inconel 600 construction resist corrosion and humidity. Certified for potentially explosive atmospheres under LCIE 08 ATEX 6017 X II 1 G (Zones 0, 1, 2), it meets NRC Guide 1.133 and IEEE 323-1974, and is qualified to DIN 25.475.1.

Applications and Integration
In nuclear power plants, the 144-901-000-212 monitors loose parts with radiation resistance—gamma flux of 1011 erg/g and neutron flux of 1018 n/cm² cause no effect. In oil and gas, its ATEX certification permits use in Zone 0, 1, and 2 areas. For industrial automation, the wide frequency response and high resonance frequency support machinery health monitoring. The charge output requires a compatible charge converter; verify cable capacitance (80 pF pole-to-pole plus 200 pF/m) with your signal processing setup.
Installation and Maintenance
Mount the accelerometer inside a tube using four M6 Allen screws at 15 Nm torque. The hermetically welded Inconel 600 housing needs only periodic inspection of mounting torque and cable condition. For explosive atmospheres, follow the manufacturer’s safety manual and local regulations. No internal repairs are recommended. Please verify current lifecycle status and availability with Oil AutoTech before ordering.
