AVC 3000 is a triple channel, portable conditioner for IEPE (ICPP®) signal with a built-in battery pack. It enables to perform machines vibration measurements based on diagnostic standards, even in difficult conditions.
AVC 3000 is a triple channel, portable conditioner for IEPE (ICPP®) signal with a built-in battery pack. Each channel has an independent control of gain level and frequency response. Settings can be adjusted by buttons on the front panel. The module has built-in sensor circuit diagnostics and detects short and open circuits in the measurement chain. The device status is indicated by LEDs on the front panel, which show as follows:
AVC 3000 features an innovative ICPP® input conditioning circuit, which has a very short response time of the impulse excitations (e.g. force signal from sensor built in a modal hammer used for modal analysis) and high output signal stability in time (lack of voltage signal fluctuation at zero excitation, which is typical for standard ICPP® signal conditioners). Configurable gain level (0dB, 20dB, 40dB) allows the module to be used with sensors having various sensitivity, as well as perform measurements in a wide range of excitation range. The low pass and high pass filters (typically 10Hz and 1kHz) allow machine vibration measurements according to diagnostic norms. The high-grade aluminium housing and the keypad made from durable foil make the device very suitable for work in a harsh industrial environment. The battery power supply allows the measurements without access to the electrical socket.
