Industrial PV91C009 Piezoelectric Accelerometer

The RION PV91C009 Piezoelectric Accelerometer is a compact, lightweight sensor with a built‑in amplifier designed for high‑temperature vibration measurements. It delivers a sensitivity of 1 mV/(m/s²), a frequency response from 1 Hz to 20 kHz (±10%), and a maximum usable acceleration of 5000 m/s² peak. The device operates from −50 °C to +170 °C and mounts with M3 screws; its body is about 7 mm across (hex) and 12.5 mm high (excluding the connector), with a mass of roughly 1.8 g. The package includes a 2 m low‑noise output cable (VP‑51LC) and mounting hardware (VP‑53K screws, VP‑53W attachment, plus a 7 mm spanner and a hex key). Ideal for rapid, direct‑output vibration measurements in structural testing, machinery monitoring, and automotive or aerospace applications where a small, rugged piezoelectric accelerometer with an integrated amplifier is advantageous, the PV91C009 is compatible with RION’s PV‑Series measurement ecosystem and simplifies signal conditioning by providing a readily usable voltage output suitable for vibration meters and data acquisition systems.
