The Bently Nevada 350500-00-00-00-11-00 Dynamic Pressure Charge Amplifier (DPCA) is a key component in dynamic pressure sensing systems, specifically engineered to monitor pressure pulsations caused by combustion instability in gas turbine engines. It works in conjunction with high-temperature piezoelectric pressure sensors, low-noise interconnect cables, and monitoring devices to provide accurate and reliable pressure measurements in harsh industrial environments.
This amplifier converts the sensor charge signal into a low-impedance voltage output, making it compatible with Bently Nevada monitoring devices such as the 3500/64 Dynamic Pressure Monitor. The DPCA features an input sensitivity of 16 pC/psi (232 pC/bar), an output sensitivity of 100 mV/psi (1.45 V/bar) ±2% @ 150 Hz, a dynamic range of ±50 psi pk, and common-mode rejection of -40 dB or better. Its high low-pass frequency option ensures precise signal fidelity.
Designed for flexibility and robustness, the 350500-00-00-00-11-00 comes with DIN mounting and MIL connector, supports operating temperatures from -20°C to +70°C and storage temperatures from -40°C to +85°C, and operates reliably under 0% to 95% non-condensing relative humidity. The interconnect cable is low-noise and environmentally robust, allowing accurate signal transmission from the sensor to the amplifier even in challenging conditions.
With its versatile design, the 350500 DPCA can be used with multiple sensors for combustion instability monitoring. It provides a safe, standardized electrical interface to Bently Nevada monitors, using -24 Vdc power, common, and signal, and is compatible with appropriate safety barriers to ensure operational safety. This makes the DPCA ideal for continuous high-fidelity monitoring of gas turbine combustion dynamics.
