Product details

Dynamic Pressure ChargeAmplifier

The 350500 Dynamic Pressure Charge Amplifier (DPCA) is acomponent in a dynamic pressure sensing system.  Thissensing system, which monitors pressure pulsations thatresult from combustion instability in gas turbine engines,consists of a charge-coupled piezoelectric pressure sensor,low noise interconnect cable, 350500 charge amplifier, andmonitoring device.

The dynamic pressure sensor should be a high temperaturepiezoelectric type that converts dynamic pressure to anoutput signal scaled in pico-coulombs per unit of pressure. The 350500 charge amplifier design allows its use with anumber of sensors designed to monitor combustioninstability.

The interconnect cable, which connects the sensor with thecharge amplifier, is a specially designed low-noise,environmentally robust cable. The 350500 DPCA offers twointerconnect cable options.

The 350500 charge amplifier converts the sensor chargesignal to a low impedance voltage output signal.  This signalis suitable for Bently Nevada monitors such as the 3500/64Dynamic Pressure Monitor. The electrical interface from themonitor to the charge amplifier, which consists of –24 Vdcpower, common, and signal, is the same as that for a BentlyNevada Proximitor.  Appropriate safety barriers can be usedbetween the charge amplifier and the monitoring device.
