Description

The IPC704P-CP237 244-704-000-032 is a configurable signal conditioner and charge amplifier module designed for critical industrial vibration measurement chains. This high-reliability AMP MODULE processes alternative electrical charge signals generated by piezoelectric sensors, such as accelerometers or dynamic pressure transducers, and transforms them into standard industrial monitoring signals. The board features an optional integrator to directly produce a velocity output from acceleration raw inputs, as well as highly flexible output electronics configured for either 2-wire current transmission or 3-wire voltage transmission. Engineered to maintain high signal linearity over long distances, it bridges the gap between field-mounted harsh environment sensors and centralized distributed control systems (DCS) or machinery protection racks.
