What Is the Vibro Meter 143-104-000-101?
The Vibro Meter 143-104-000-101 is a CP 104 piezoelectric pressure transducer built around a VC2 single crystal element. That compression-mode design delivers an extremely stable instrument for long-term monitoring or development testing. With no input power requirement, it generates a charge output and pairs with a charge converter for signal processing.
Engineers specify this transducer when they need reliable dynamic pressure data in harsh environments. The hermetically welded Inconel 600 body resists corrosion and humidity, while the wide temperature range covers cryogenic through high-temperature service.
Key Parameters That Drive Performance
Sensitivity and Measuring Range
The 143-104-000-101 delivers 190 pC/bar nominal sensitivity at 2 Hz. Its dynamic measuring range spans 0.00005 bar to 20 bar nominal, with overload capacity up to 100 bar for spikes. Linearity holds within ±1% across the dynamic measuring range.
Frequency Response
Frequency response runs from 2 Hz to 6000 Hz ±5%. The lower cutoff frequency depends on the electronics used, so charge converter selection matters. Resonant frequency exceeds 30 kHz, keeping the usable band well clear of resonance.
Environmental Durability
The temperature range reaches -196°C to +350°C. Acceleration sensitivity stays at or below 0.1 pC/g (0.0005 bar/g), and the unit tolerates shock acceleration below 2000 g peak (half sine, 1 ms) along the sensitive axis. Gamma flux at 1011 erg/g and neutron flux at 1018 n/cm2 produce no effect.
Electrical Characteristics
Capacitance measures 85 pF nominal pole/pole and 30 pF nominal pole/ground. Internal insulation resistance is minimum 109 Ω (107 Ω at 300°C). Signal transmission uses a 2-pole system insulated from the casing with charge output.
Where This Transducer Fits
The CP 104 suits long-term monitoring and development testing across oil, gas, and industrial automation. Its ABWR primary circuit capability and IEEE 323-1974 compliance make it a practical choice for nuclear-adjacent pressure monitoring. The acceleration-compensated design reduces vibration-induced errors in pump and compressor testing.
For teams replacing failed dynamic pressure sensors, the 143-104-000-101 offers a drop-in option with proven reliability. Oil AutoTech provides hands-on technical selection help to match the right cable and charge converter to your application.
Installation and Mounting
Mount the transducer using 3 Allen screws M5 with a fastening torque of 10 Nm. The unit may operate with either softline or hardline cables depending on the required temperature. Dynamic calibration is performed at the factory at 1 bar peak and 2 Hz (23°C), and no subsequent calibration is necessary.
