Product Description
Model: IPC704, P/N:244‑704‑000‑022 Brand: Vibro‑Meter (Meggitt) Product Name: Piezoelectric Signal Conditioner (Charge Converter)
IPC704 (244‑704‑000‑022) is a charge‑converting signal conditioner for machinery protection applications. It interfaces with CA‑series piezoelectric accelerometers and CP‑series dynamic pressure sensors, converting charge signal from piezo sensors into standard current / voltage analog outputs for long‑cable transmission. Equipped with configurable high‑pass / low‑pass filters, optional integrator for velocity output and RFI noise protection. Explosion‑proof certified variants available for hazardous‑area deployment.
