DESCRIPTION

The IPC704 signal conditioner converts the chargebased signal from a piezoelectric-based transducer

into a current or a voltage signal. This current or voltage signal is transmitted to the processing electronics

via a standard 2-wire or 3-wire transmission cable.

The current modulation technique allows transmission over a distance of up to 1 km. A GSI galvanic

separation unit is required for this configuration.

The electronic circuitry of the IPC704 signal conditioner is incorporated into a moulded aluminium

enclosure. The signal conditioner has configurable

high-pass and low-pass filters and an optional integrator to give a velocity output. Furthermore, RFI filters protect the input and output against radiofrequency interference and other electromagnetic

influences.

A range of installation options are available for the

IPC704 signal conditioner, including:

» A polyester enclosure providing environmental

protection against dust, oil and water jets.

» A mounting adaptor allowing the IPC704 signal

conditioner to be mounted on a DIN rail.
