 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

 DESCRIPTION (continued)

Two versions of the IPC704 signal conditioner are available:

» An IPC704 for sensors using standard piezoelectric materials, for example, CAxxx, CP10x and CP2xx (ordering number 244-704-000-042-... )

» An IPC704 for sensors using GaPO4 piezoelectric material, for example, CP50x (ordering number 244-704-000-511-... ).
