Its core function is to perform real-time, high-precision monitoring of dynamic pressure fluctuations, acoustic oscillations, and combustion instabilities inside large rotating machinery (such as gas turbines and compressors), with a measurement range of 0 to 3000 kPa. This sensor has extremely strong environmental adaptability; its robust explosion-proof design can withstand high-intensity mechanical vibrations, ensuring continuous and stable output of critical status data even in hazardous industrial environments.

Its working principle is based on the advanced piezoelectric effect. The core component inside the sensor uses VC2-type single-crystal piezoelectric material as the sensing element. When there are instantaneous pressure fluctuations in the airflow or fluid in the external environment, this dynamic pressure directly acts on the piezoelectric crystal, causing it to undergo minute mechanical deformation.
Due to the physical properties of the piezoelectric crystal, this deformation induces a change in charge on the crystal surface, and the amount of this change is proportional to the magnitude of the applied force, thus generating a stable charge output (sensitivity of 50 pC/psi).
This weak charge signal is then transmitted to a preamplifier via a specially designed low-noise extension line, where it is converted into a standard voltage or current signal, thereby accurately converting the rapidly changing mechanical pressure into an electrical signal that the monitoring system can analyze.
Because the CP515 outputs an unprocessed static charge signal, it cannot be directly connected to a standard PLC. To build a complete monitoring loop, the following hardware components are required:
Signal Conditioner: Typically used in conjunction with the IPC707 signal conditioner. This converter transforms the high-impedance pC charge signal into a linear current (or voltage) signal.
Intermediate Extension Cable: Utilizes a dedicated low-noise transmission path, such as the EC240 flexible cable assembly (922-240-000-331), to securely connect the high-temperature turbine housing wall to the cleanroom electronics rack.
Rack Protection Terminals: Can be integrated into downstream standard VM600 or VibroSmart® plant control architectures.
