Product Overview
When a gas turbine pressure channel goes down, every hour of downtime costs money. The Vibro Meter CP 216 piezoelectric pressure transducer, ordering number 143-216-000-161, is built for exactly those moments. It is a compression-mode dynamic pressure transducer from the Vibro-Meter product line, designed for long-term monitoring and development testing in extreme environments. A man-made piezoelectric element gives the CP 216 an extremely stable output, so maintenance engineers can trust the reading, not just the hardware.
Technical Specifications
What the Key Parameters Mean in Practice
The sensitivity of 200 pC/bar (13.8 pC/psi) delivers a strong charge signal that survives long cable runs to the signal conditioner. The dynamic measuring range spans 0.0005 bar to 250 bar, with spike overload capacity up to 350 bar, so pressure transients will not damage the unit. Linearity stays within ±1% over the dynamic measuring range, keeping measurement quality predictable.
Temperature capability is the headline. Continuous operation covers −54 to 470°C, and extreme applications reach −70 to 520°C. The Vibro-Meter high-temperature connector extends to 650°C, while the LEMO option covers −55 to 155°C. Frequency response runs from 2 Hz to 15 kHz ±5%, capturing both slow trends and fast combustion dynamics. The transducer needs no input power — it is a passive charge output device, which removes one more failure point from the loop.

Built for Gas Turbine Monitoring
Dynamic pressure monitoring on gas turbines demands reliability over a wide temperature range. The CP 216 fits this role directly. Its NIMONIC alloy 90 housing is hermetically welded, and the mineral insulated cable uses INCONEL alloy 600, so corrosion and humidity stay outside where they belong. Radiation tolerance is documented too: gamma flux at 1010 erg/g and neutron flux at 1017 n/cm2 show no effect, which matters in nuclear-adjacent or heavily instrumented plants.
For maintenance teams, the practical benefit is fewer surprises. Factory dynamic calibration at 1 bar peak and 2 Hz means no subsequent calibration is necessary. A transducer that holds its accuracy without routine recalibration saves labor hours and reduces the risk of introducing errors during service.
Installation and Service Notes
The CP 216 ships with an integral mineral insulated cable with two conductors. Field termination uses either a LEMO connector or the Vibro-Meter high-temperature connector, depending on your ordered configuration. Cable assemblies are available to connect the transducer to an IPC 704 signal conditioner. Because the signal is a charge output on a 2-pole system insulated from the casing, keep cable routing clean and connectors dry during installation. Inspect the connector and cable jacket periodically for mechanical damage, and follow the manufacturer’s documentation for all maintenance work.
Compatibility and Integration
This transducer pairs with charge converters and signal conditioners such as the IPC 704. It carries no active electronics, so integration focuses on correct cabling and grounding rather than configuration. If your measurement chain uses a different conditioner, confirm input compatibility before ordering.
Selection Checklist
Before purchasing, verify the connector type you need, the required cable length, and the signal conditioner in your loop. The ordering configuration for 143-216-000-161 specifies the Vibro-Meter high-temperature connector with a 5 m cable.
