Product Overview
When dynamic pressure monitoring must survive the extreme heat of a gas turbine, standard transducers fall short. The Vibro Meter CP 216, ordering number 143-216-000-021, is a compression-mode piezoelectric pressure transducer built for exactly that environment. It uses man-made piezoelectric material to deliver an extremely stable charge output for long-term monitoring or development testing. With no input power required, it keeps installation simple and reliable.
Key Parameters That Matter
Sensitivity and Measuring Range
The CP 216 delivers a typical sensitivity of 200 pC/bar (13.8 pC/psi) at 2 Hz. Its dynamic measuring range spans 0.0005 bar to 250 bar, with overload capacity up to 350 bar for spikes. Linearity stays within ±1% over the dynamic range, so your data reflects real pressure events, not sensor drift.
Temperature and Frequency Performance
The transducer handles continuous temperatures from −54 to 470°C and extreme applications from −70 to 520°C. Frequency response covers 2 Hz to 15 kHz ±5%, with a resonant frequency above 80 kHz. This combination suits both slow thermal cycling and fast pressure pulsations.
Construction and Insulation
The hermetically welded NIMONIC alloy 90 body resists corrosion and humidity. Internal case insulation and a two-pole system insulated from the casing support clean charge output. The integral mineral insulated cable uses twin conductors and can be terminated with a LEMO or Vibro-Meter high-temperature connector.
Where the CP 216 Proves Its Value
Gas turbine operators use the 143-216-000-021 for combustion dynamics monitoring, where pressure oscillations and high temperatures occur together. Development engineers rely on it for test-cell pressure measurements across wide thermal ranges. In explosive atmospheres, its certification for potentially explosive environments supports safe dynamic pressure monitoring. Each scenario demands a transducer that stays stable without power or frequent calibration.
Installation and Integration Notes
Mount the transducer so the sensitive axis aligns with the pressure direction. The mineral insulated cable is integral, so plan routing to protect it from excessive bending. Cable assemblies are available to connect the transducer to an IPC 704 signal conditioner. When wiring into fieldbus or control networks, confirm cables and gateways with your supplier. Oil AutoTech provides hands-on technical selection help to match connectors and cable lengths to your setup.
Reliability and Maintenance
Factory dynamic calibration at 1 bar peak and 2 Hz means no subsequent calibration is necessary. Periodic inspection should focus on cable condition, connector seating, and mechanical mounting. The hermetically welded NIMONIC alloy 90 housing resists corrosion and humidity, supporting long service intervals. For safety-related installations, follow the manufacturer’s safety manual and inspect periodically.
Buyer’s Checklist
Before ordering, verify your required cable length, connector type, and signal conditioner compatibility. The standard configuration includes a 0.5 m cable with LEMO connector. Confirm the operating temperature range matches your application, especially if you need the extreme −70 to 520°C capability.
