The AVC3000 is an portable 3 channel IEPE sensor interface. It has 4mA/24V supplies for sensors with integrated amplifiers. For low level signal amplification it features three selectable gain ranges and individually selectable highpass- and lowpassfilters for all three channels. Indicators for sensor condition and signal overload further minimize the risk of handling errors. The integrated rechargeable battery ensures a long operating time and the unit may be charged and operated at the same time.
