The Dytran model 4753B is a miniature in-line charge amplifier designed for use with high temperature charge mode accelerometers. This IEPE unit is powered using constant current sources and is compatible with IEPE designated instrumentation.
Model 4753B is specifically designed to operate with high temperature charge mode sensors because of its ability to tolerate very low levels of insulation resistance. It can accept sensors with insulation resistance as low as 100kOhms without any deterioration in performance.
Available with a sensitivity of 10 mV/pC, the model 4753B is offered with a 10-32 jack input connector, BNC jack output connector and features a short power-up time of <5 seconds.
