143-104-000-101 Vibro-Meter CP 104 Pressure Sensor

143-104-000-101 Vibro-Meter CP 104 Pressure Transducer

Product Introduction of CP 104 Series

The 143-104-000-101 represents a high-performance solution for dynamic pressure measurement within the Meggitt vibro-meter® product catalog. Specifically, this CP 104 model utilizes a specialized VC2 type single crystal material operating in compression mode. Because the design incorporates sophisticated acceleration compensation, the sensor maintains extreme stability during intense mechanical vibration. Furthermore, the unit is constructed with a hermetically welded Inconel 600 housing to withstand corrosive industrial atmospheres.

Meanwhile, this piezoelectric device offers internal case insulation to ensure high signal integrity in complex electrical environments. Additionally, the 143-104-000-101 is fully operational in the primary circuits of advanced boiling water reactors (ABWR). Specifically, the transducer meets the rigorous safety and reliability standards outlined in IEEE 323-1974. Therefore, engineering teams frequently deploy this specific model for critical monitoring in gas turbines and nuclear power generation facilities.

143-104-000-101 Technical Specifications and Performance

The performance of the 143-104-000-101 is defined by its precise sensitivity and broad frequency response range. First, the unit delivers a nominal sensitivity of 190 pC/bar, allowing for the accurate detection of pressure transients. Additionally, the dynamic measuring range extends from 0.00005 bar to 20 bar nominal for varied industrial applications. Specifically, the frequency response spans from 2 Hz to 6000 Hz, ensuring comprehensive data capture across the spectrum.

Furthermore, the internal insulation resistance is rated at a minimum of 109 Ω at room temperature. Besides its core sensing capabilities, the device can handle temporary pressure spikes reaching up to 100 bar without failure. For instance, the 143-104-000-101 maintains a resonant frequency greater than 30 kHz to avoid interference with operational signals. Finally, the acceleration sensitivity remains below 0.1 pC/g, which minimizes noise corruption from surrounding structural vibrations.

Mechanical and Environmental Parameters for CP 104 Sensor

Regarding physical durability, this pressure transducer is engineered to survive in the most demanding environmental conditions. Specifically, the 143-104-000-101 operates across a massive temperature range from -196°C to +350°C. Meanwhile, the Inconel 600 construction provides a robust barrier against humidity, steam, and radioactive radiation fluxes. In addition, the device maintains its performance even after exposure to high Gamma and Neutron flux levels.

Specifically, the CP 104 model is built to tolerate mechanical shock accelerations up to 2000 g peak along its sensitive axis. Moreover, the unit remains stable at elevated temperatures, retaining an insulation resistance of 107 Ω even at 300°C. Therefore, it is perfectly suited for long-term installation in high-heat zones where standard sensors would fail. Furthermore, the 150g transducer head allows for secure mounting on high-pressure piping systems without adding excessive mass.

143-104-000-101 Installation Guide and Usage

Successful deployment of the CP 104 requires precise mechanical fastening to ensure accurate pressure transmission and seal integrity. First, select either softline or hardline cables depending on the specific temperature requirements of your operational environment. Next, secure the 143-104-000-101 to the mounting surface using three M5 Allen screws in the designated pattern. Specifically, you must apply a fastening torque of 10 Nm to achieve a reliable and vibration-resistant connection.

Additionally, the transducer utilizes a 2-pole system that is insulated from the casing for a clean charge output signal. Furthermore, you must connect the output to a compatible charge converter to process the signal for your monitoring system. Meanwhile, ensure that the cable connections are clean and dry to maintain the high internal insulation resistance. Finally, verify the orientation of the sensitive axis to ensure the acceleration compensation features function at their maximum efficiency.
