Product Overview
When dynamic pressure monitoring demands reliability in extreme environments, the 143-216-000-031 delivers. This Vibro Meter CP 216 piezoelectric pressure transducer uses man-made piezoelectric material in a compression-mode design, producing an exceptionally stable device for long-term monitoring or development testing. With a continuous temperature range of −54 to 470°C and extreme capability to 520°C, it handles conditions that defeat ordinary sensors.
Key Specifications That Matter
The CP 216 offers 200 pC/bar sensitivity and a dynamic measuring range of 0.0005 bar to 250 bar. Overload capacity reaches 350 bar for spikes. Frequency response spans 2 Hz to 15 kHz with ±5% tolerance, while linearity stays within ±1% over the dynamic range. The transducer weighs just 12 g, and its mineral insulated cable adds 25 g/m. These specs mean accurate capture of fast pressure events without signal degradation.
Built for Demanding Applications
Gas turbine monitoring stands out as a primary use case. The CP 216 thrives where high temperatures and vibration would destroy lesser transducers. Its NIMONIC alloy 90 body, hermetically welded, resists corrosion and humidity. Radiation tolerance—gamma flux at 1010 erg/g and neutron flux at 1017 n/cm2 with no effect—suits nuclear-adjacent environments. The internal case insulation and 2-pole system isolated from casing ensure clean charge output.
Installation and Integration
The transducer ships with a 1 m mineral insulated cable, twin conductors, terminated with a LEMO connector. For higher temperatures, a Vibro-Meter high-temperature connector is available. Cable assemblies connect to the IPC 704 signal conditioner. No input power is required—the piezoelectric element generates charge directly. When routing cables in high-vibration areas, secure them to prevent wear. The LEMO connector operates from −55 to 155°C, while the high-temperature option extends to 650°C.
Maintenance and Reliability
Factory calibration at 1 bar peak and 2 Hz means no subsequent calibration is necessary. Periodic inspection of cable integrity and connector condition is recommended. The hermetically welded construction minimizes environmental ingress. For long-term installations, verify mounting torque and cable strain relief. This transducer is designed for years of service with minimal intervention.
Selection Guide
Before ordering, confirm your system uses charge-mode signal processing. The CP 216 requires a charge converter, such as the IPC 704. Verify the connector type matches your existing cabling—LEMO or Vibro-Meter high-temperature. Cable length is 1 m as standard. For replacement or upgrade projects, check compatibility with your signal conditioner’s input specifications.
