Dytran's new inline charge amplifier operates in high-humidity and dirty environments
Dytran Instruments
Model 4752B charge amplifier
Dytran Instruments has introduced a miniature inline charge amplifier designed for use with high-temperature charge-mode accelerometers.
The Model 4752B device is powered using constant-current sources and is compatible with IEPE-designated instrumentation.
According to the company, charge amplifiers convert electrostatic, high-impedance charge signals generated by charge generators, such as charge-mode accelerometers, to lower-impedance voltage-mode signals that can drive longer cables with signal degradation.
Key specifications
• Accepts sensors with insulation resistance as low as 100kohm
• Available with a sensitivity of 10mV/pC
• Offers a fast turn-on time of less than five seconds
• Hermetically sealed for operation in high-humidity and dirty environments
