Charge Converters condition piezoelectric sensor signals.
Press Release Summary:
Models 422E35 and 422E36 convert charge-mode signals into low-impedance voltage signals for input to readout, recording, and analysis instruments. In-line units, for use with high-temperature piezoelectric acceleration, pressure, and force sensors, accept source resistances as low as 10 k ohm and temperatures above 400°F. Converters are suitable for harsh environments, such as vibration monitoring and testing of turbines, engines, and exhaust systems.Original Press Release:
In-Line Charge Converters for Conditioning High-Temperature, Charge Mode, Piezoelectric Sensors
October 1, 2002, Depew, NY - Models 422E35 and 422E36 In-Line Charge Converters from the Electronics Division of PCB Piezotronics, Inc., serve to convert charge mode piezoelectric sensor signals into low-impedance voltage signals for input to readout, recording, and analysis instruments. These units are designed for use with high-temperature piezoelectric acceleration, pressure, and force sensors, as they will accept source resistances as low as 10k ohm.
The insulation resistance of a charge mode sensor will be reduced as its temperature is raised. At temperatures above 400°F (204°C), this resistance could be lowered to a level that may cause typical charge converters to shut off. With the PCB 422E35 and 422E36 models, this situation is avoided because the converters are specifically designed to accommodate low source resistances.
The In-Line Charge Converters operate with ICP® sensor signal conditioners or readout devices which have an ICP sensor input, and are typically used in harsh, high-temperature environments such as vibration monitoring and testing of turbines, engines, and exhaust systems.
