When Gas Turbines Demanded More, the CP 216 Answered
As gas turbines grew hotter and faster, conventional pressure sensors hit their limits. Engineers needed dynamic pressure data at temperatures that melted standard electronics. Vibro-Meter responded with the CP 216, a piezoelectric transducer built for the extreme. The 143-216-000-131 brings that capability to your plant, ready-to-ship from Oil AutoTech.
What Is the Vibro Meter CP 216?
The CP 216 is a compression-mode dynamic pressure transducer from the Vibro-Meter product line. Its man-made piezoelectric material delivers an extremely stable charge output, making it ideal for long-term monitoring and development testing in harsh environments. With no input power required, it simplifies installation where cabling is already complex.
Key Parameters That Matter
| Specification | Value |
|---|---|
| Sensitivity | 200 pC/bar (13.8 pC/psi) |
| Dynamic range | 0.0005 to 250 bar |
| Overload capacity | Up to 350 bar (spikes) |
| Frequency response | 2 Hz to 15 kHz ±5% |
| Continuous temperature | −54 to 470°C |
| Extreme temperature | −70 to 520°C |
| Linearity | < ±1% |
| Acceleration sensitivity | ≤ 0.5 pC/g |
These numbers translate to real capability. The 200 pC/bar sensitivity captures subtle pressure fluctuations, while the 350 bar overload tolerance protects against spikes. The wide frequency range covers both low-frequency pulsations and high-frequency combustion dynamics.
Where the CP 216 Proves Its Worth
Gas turbine combustion monitoring is the classic application. The transducer survives radiant heat and vibration that destroy ordinary sensors. In development testing, engineers rely on its linearity and stability to validate new combustor designs. For oil and gas compressor stations, the CP 216 monitors pulsation and surge events, helping prevent catastrophic failures.
Integration and Installation
The CP 216 uses a two-pole system insulated from the casing, with a charge output that requires a charge converter. It comes with an integral mineral insulated cable (two conductors) and a Vibro-Meter high-temperature connector. Cable assemblies connect to an IPC 704 signal conditioner. When wiring into existing monitoring systems, confirm cable length and connector type with your supplier.
Reliability in Extreme Conditions
The transducer’s NIMONIC alloy 90 housing is hermetically welded for corrosion and humidity resistance. It withstands shock up to 2000 g and shrugs off gamma and neutron radiation. Factory calibration at 1 bar peak and 2 Hz means no subsequent calibration is necessary. For maintenance, periodic visual inspection of the cable and connector is recommended; follow the manufacturer’s safety manual for any servicing.
