Six Channel Charge Amplifier
?Model YE5853 ?
?YE5853 charge amplifier is a kind of multi-channel modular charge amplifier, connecting ?with piezoelectric acceleration sensor?as a test system, to measure the physical parameters, such as vibration, shock, ?be widely used in mechanical manufacture, power, aviation, navigation, construction, chemical explosion and other departments.This instrument adopts multi channel interpolation type structure, each instrument contain 1 ∽ 6 measurement channels, so for multipoint tests, it is a best economy choice.
