Product Overview
Gas turbine operators know the challenge: pressure sensors that fail under extreme heat or vibration. The 143-216-000-111 from Vibro Meter solves this. It is a CP 216 piezoelectric pressure transducer built for dynamic pressure monitoring in the harshest environments. Using man-made piezoelectric material in a compression-mode design, it delivers an extremely stable charge output for long-term monitoring or development testing.
The transducer handles continuous temperatures from −54 to 470°C and extreme applications from −70 to 520°C. It measures dynamic pressure from 0.0005 bar to 250 bar, with spike overload capacity up to 350 bar. Sensitivity is 200 pC/bar with a frequency response of 2 to 15000 Hz ±5%. No input power is required — it generates a charge output directly.

What These Specs Mean in Practice
The 200 pC/bar sensitivity gives a strong, clean signal for charge converters. The ±1% linearity ensures accurate readings across the full range. With no input power needed, the transducer works passively — ideal for hazardous areas. The NIMONIC® alloy 90 body is hermetically welded for corrosion and humidity resistance.

Unlike standard transmitters, the CP 216 handles extreme heat and high-frequency dynamic events. It is not a replacement for general-purpose pressure transmitters — it is a specialized tool for gas turbines and test stands.
Industry Applications
Gas turbine monitoring. The CP 216 excels in combustion instability detection. Its 15 kHz frequency response captures pressure oscillations that lower-bandwidth sensors miss. The 520°C extreme rating covers exhaust-adjacent locations.
Development testing. Engineers use the 143-216-000-111 for dynamic pressure measurement in engine test cells. The mineral insulated cable and high-temperature connector survive rigors that destroy standard cables.
Nuclear and radiation environments. Gamma flux of 1010 erg/g and neutron flux of 1017 n/cm² cause no effect. This makes the transducer suitable for specialized monitoring tasks.
Installation and Setup
The CP 216 uses a 2-pole system insulated from casing. The integral mineral insulated cable has twin conductors. You can terminate with either a LEMO connector or a Vibro-Meter high-temperature connector. Cable assemblies connect the transducer to an IPC 704 signal conditioner.
For integration with charge amplifiers or signal conditioners, verify input compatibility. The transducer requires no power, but the charge converter does. Mounting depends on your specific mechanical interface — consult the mechanical drawings.
Maintenance and Reliability
Factory calibration at 1 bar peak and 2 Hz means no subsequent calibration is necessary. The hermetically welded NIMONIC® alloy 90 housing resists corrosion. For long-term reliability, inspect the cable and connector periodically. Avoid sharp bends in the mineral insulated cable.
