Industry Trends in Dynamic Pressure Monitoring
Modern industrial environments demand reliable pressure monitoring under extreme conditions, especially in sectors like power generation and aerospace. The trend toward predictive maintenance and condition monitoring drives the need for robust sensors that can withstand high temperatures and pressures. The Vibro Meter 143-216-000-051 CP 216 addresses these requirements with its extreme temperature capability and high-pressure performance.
Introducing the 143-216-000-051 CP 216
The 143-216-000-051 is a piezoelectric pressure transducer from the Vibro Meter product line, part of the CP 216 series. This compression-mode dynamic pressure transducer uses man-made piezoelectric material for exceptional stability. It is designed for long-term monitoring or development testing in extreme environments, such as gas turbines.
Key features include extreme temperature capability from -70 to 520°C and high-pressure capability up to 350 bar. The transducer offers a pressure sensitivity of 200 pC/bar and a frequency range of 2 Hz to 15 kHz. It also includes internal case insulation and is certified for use in potentially explosive atmospheres.
Technical Specifications and Performance
The CP 216 transducer delivers a dynamic measuring range from 0.0005 bar to 250 bar, with an overload capacity up to 350 bar. Its linearity is less than ±1% over the dynamic measuring range, ensuring accurate readings. The resonant frequency exceeds 80 kHz, and the frequency response is 2 to 15000 Hz ±5%.
Acceleration sensitivity is ≤ 0.5 pC/g, and the transducer has a nominal pole-to-pole capacitance of 320 pF plus 200 pF/m of cable. Internal insulation resistance is greater than 109 Ω, and at 450°C it remains above 5x104 Ω. The transducer can withstand shock acceleration less than 2000 g peak along the sensitive axis.

- Temperature Range: The CP 216 operates from -70 to 520°C for extreme applications, while many standard transducers are limited to -40 to 150°C.
- Pressure Capability: The CP 216 handles up to 350 bar, whereas typical sensors max out at 100-200 bar.
- Sensitivity: With 200 pC/bar, the CP 216 offers high sensitivity for precise measurements, compared to 50-100 pC/bar in some alternatives.
- Frequency Range: The CP 216 covers 2 Hz to 15 kHz, suitable for both low and high-frequency dynamic events, while some sensors focus on narrower bands.
This comparison highlights the CP 216's suitability for demanding applications like gas turbine monitoring, where extreme conditions are common.
Applications in Modern Manufacturing
The CP 216 is ideal for dynamic pressure monitoring over a wide temperature range, requiring high reliability. In gas turbines, it monitors combustion dynamics and pressure fluctuations to optimize performance and prevent damage. It is also used in development testing for engines and compressors, where accurate pressure data is critical.
Another application is in industrial processes involving high-temperature fluids or gases, such as chemical reactors or steam systems. The transducer's ability to withstand radiation (gamma flux up to 1010 erg/g and neutron flux up to 1017 n/cm2) makes it suitable for nuclear environments.

Real-World Application Example
In a typical gas turbine monitoring scenario, the CP 216 is installed in the combustion chamber to measure dynamic pressure changes. The transducer's extreme temperature capability up to 520°C ensures reliable operation even during startup and shutdown cycles. Its high-pressure capability up to 350 bar handles pressure spikes, while the frequency range captures both low-frequency instabilities and high-frequency combustion events.
