PCB Piezotronics, Inc. In-Line Charge Converter 422E65/A

The In-Line Charge Converter model 422E65/A from PCB Piezotronics, Inc. features a sensitivity of 1 mV/pC and operates within an input range of ¬±5000 pC. It has a low frequency response of 5 Hz and a high frequency response of 35 kHz at 4 mA. The device exhibits non-linearity of ,⧠1.0% FS and can operate in temperatures ranging from -65 to +250 ¬8F (-54 to +121 ¬8C). This converter supports an excitation voltage of +18 to 28 VDC and a constant current excitation of 2.2 to 20 mA, providing an output voltage of ¬±5 V with an output impedance of less than 20 Ohm. The device is designed to withstand a maximum shock of 1000 g pk and is sealed with a welded stainless steel housing. It features 10-32 coaxial jacks for both input and output connections and has a compact size of 0.50 in diameter and 3.0 in length, weighing 0.8 oz. The converter is also radiation hard, with limits of ,⧠1 Mrad for integrated gamma flux and ,⧠1010 N/cm¬= for integrated neutron flux. It has a maximum allowable input capacitance of 20,000 pF and a minimum required input resistance of 10,000 Ohm. The broadband electrical noise is specified at 7.0 ¬µV across a frequency range of 1 to 10,000 Hz.
