Product Overview
The 143-216-000-041 is a Vibro Meter CP 216 piezoelectric pressure transducer built for dynamic pressure monitoring in the most demanding industrial environments. With a pressure sensitivity of 200 pC/bar and an extreme temperature capability reaching 520°C, this transducer delivers reliable performance where standard sensors fail. Its compression-mode design uses man-made piezoelectric material to produce an extremely stable device for long-term monitoring and development testing. The integral mineral insulated cable with twin conductors can be terminated with a LEMO connector or a Vibro-Meter high-temperature connector. For oil, gas, and industrial automation teams, this means fewer replacements and lower total cost of ownership.

Cost-Efficiency Through Extreme Capability
The 143-216-000-041 excels where downtime is expensive. Its 200 pC/bar sensitivity captures subtle pressure fluctuations, enabling early detection of combustion instability in gas turbines. The wide frequency response of 2 Hz to 15 kHz allows one sensor to cover multiple monitoring points, reducing inventory costs. With an overload capacity up to 350 bar, the transducer withstands pressure spikes that would destroy lesser sensors, cutting replacement frequency and maintenance labor. The NIMONIC alloy 90 housing with hermetic welding resists corrosion and humidity, extending service life in harsh oil and gas installations. Because the device requires no input power, wiring complexity and associated installation costs drop significantly. Internal case insulation and certification for explosive atmospheres add safety without extra protective enclosures.
Applications in Oil, Gas, and Power Generation
Gas turbine monitoring is a primary application. The CP 216 handles continuous temperatures to 470°C and extreme excursions to 520°C, making it ideal for exhaust and combustion section measurements. In oil and gas processing, the transducer’s 350 bar overload capability suits high-pressure pipelines and compressor stations. For development testing, the high resonant frequency above 80 kHz ensures accurate capture of fast pressure transients. Each application benefits from the transducer’s stability, which reduces calibration downtime and preserves measurement integrity over years of operation.
Integration and Maintenance
The 143-216-000-041 connects to an IPC 704 signal conditioner via its mineral insulated cable. Cable assemblies are available for this purpose. The LEMO connector operates from −55 to 155°C, while the Vibro-Meter high-temperature connector extends to 650°C. For fieldbus networks, wiring may require an external gateway or connection module; confirm cables and gateways with your supplier. Maintenance is minimal: the factory performs dynamic calibration at 1 bar peak and 2 Hz, and no subsequent calibration is necessary. Periodic visual inspection of the cable and connector is recommended. Please verify current lifecycle status and availability with Oil AutoTech before ordering.
Selection Guide
Before purchasing, confirm your system’s signal conditioning compatibility, cable length requirements, and connector type. The 143-216-000-041 ships with a 2 m cable and LEMO connector.
