Miniature In-Line Charge Amplifier for High Temperature Applications, Model 4753B

March 21, 2012 – Chatsworth, California, USA – Dytran Instruments, Inc. a leading manufacturer of piezoelectric and DC MEMS accelerometers, force and pressure transducers and associated electronics, has introduced the model 4753B, 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.

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 without signal degradation.

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. This is a typical characteristic of high temperature piezoelectric accelerometers, and would force a conventional charge amplifier to shutdown. The Dytran model 4753B 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 and BNC jack output connector, and features extremely fast turn-on time (<5 seconds).
