Solving Extreme Pressure Monitoring Challenges
When a gas turbine experiences rapid pressure fluctuations in high-temperature zones, standard sensors often fail. Engineers need a transducer that can withstand both extreme heat and high pressure without signal degradation. The Vibro Meter 143-216-000-031 CP 216 piezoelectric pressure transducer is engineered to meet these exacting demands.
This compression-mode dynamic pressure transducer uses a man-made piezoelectric material to deliver stable performance across a wide temperature range. It is designed for long-term monitoring or development testing in extreme environments, such as gas turbines.
Introducing the 143-216-000-031 CP 216
The 143-216-000-031 is part of the Vibro Meter CP 216 series, a piezoelectric pressure transducer built for extreme conditions. It offers an extreme temperature capability from −70 to 520°C and high-pressure capability up to 350 bar.
With a pressure sensitivity of 200 pC/bar and a frequency range of 2 Hz to 15 kHz, this transducer provides accurate dynamic pressure monitoring. It also features internal case insulation and is certified for use in potentially explosive atmospheres.
Technical Specifications and Performance
The CP 216 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 reliable data.
The transducer has a resonant frequency greater than 80 kHz and a frequency response of 2 to 15000 Hz ±5%. Acceleration sensitivity is ≤ 0.5 pC/g, and the internal insulation resistance is > 109 Ω, with > 5x104 at 450°C.
The transducer temperature range for continuous operation is −54 to 470°C, and for extreme applications it extends to −70 to 520°C. The Vibro-Meter high-temperature connector can withstand −70 to 650°C, while the LEMO connector is rated for −55 to 155°C.
Applications in Modern Manufacturing
The CP 216 is ideal for dynamic pressure monitoring over a wide temperature range where high reliability is required. In gas turbines, it monitors combustion dynamics and pressure pulsations that can affect efficiency and safety.
It is also suitable for development testing in extreme environments, such as rocket engines or high-temperature chemical reactors. The transducer's ability to handle gamma flux up to 1010 erg/g and neutron flux up to 1017 n/cm2 makes it valuable in nuclear applications.
Real-World Application Example
In a typical gas turbine monitoring scenario, the 143-216-000-031 is installed in the combustion chamber to measure dynamic pressure changes. The transducer's mineral insulated cable with a LEMO or high-temperature connector feeds signals to an IPC 704 signal conditioner, enabling real-time analysis of pressure spikes and combustion stability.
This setup helps operators detect early signs of combustion instability, reducing the risk of unplanned downtime and extending turbine life. The CP 216's high overload capacity ensures it survives occasional pressure spikes without damage.
Compatible Systems and Integration
The CP 216 transducer is fitted with an integral mineral insulated cable (twin conductors) that can be terminated with either a LEMO connector or a high-temperature connector developed by Vibro-Meter. Cable assemblies are available to connect the transducer to an IPC 704 signal conditioner.
The transducer operates as a 2-pole system insulated from the casing, with a charge output that requires a charge converter for signal processing. This design ensures compatibility with standard vibration monitoring systems used in industrial automation.
Frequently Asked Questions About the 143-216-000-031
What is the maximum pressure the CP 216 can handle?
The CP 216 has a high-pressure capability up to 350 bar, with an overload capacity (spikes) up to 350 bar (static + dynamic components). The dynamic measuring range is 0.0005 bar to 250 bar.
What temperature range does the transducer support?
For continuous operation, the transducer temperature range is −54 to 470°C. For extreme applications, it can operate from −70 to 520°C. The Vibro-Meter high-temperature connector supports −70 to 650°C, while the LEMO connector supports −55 to 155°C.
