Data derived from Piezoelectric Accelerometers is in the form of electrical charges proportional to the mass applied, and requires further processing in order to extract specific information. The widely used IEPE Accelerometer features an inbuilt QVC - converting the charge to a voltage prior to signal transmission. Where the signal is strong enough, minimal instrumentation is required to interface with the accelerometer. However, in some cases it will be necessary to amplify the signal with a voltage source amplifier.
IEPE Accelerometers are not suitable for some applications, and a charge output accelerometer will be required. Charge output accelerometers are able to withstand higher temperatures, and are generally more rugged, with the downside being the requirement for extra instrumentation. DJB's 04 Series provides a comprehensive range of instrumentation covering most applications, conveniently housed within module housings, with integrated power supplies.
The 04 System features Accelerometer signal processing, and signal conditioning equipment. The signals from the accelerometer can either be displayed on a screen housed within the system, or connected with front end hardware. Signals from the accelerometer can also be converted to displacement and velocity with high accuracy analogue modules.
