GE Control Mark V IS220PVIBH1A Vibration Monitor (PVIB) Pack

Getting Accurate Measurements — The Sensor Is Only Half the Story

A GE IS220PVIBH1A can be manufactured to micron-level precision, but if it is installed on a surface with pitting, rust, or mechanical runout exceeding the probe tip diameter, the output signal will be noise — not data. We see this most often on older machines where the target area has degraded over years of service.

Before ordering a replacement sensor, inspect the target surface. A clean, smooth, conductive target area (at least 2x the probe tip diameter) is essential for eddy-current probes. For velocity sensors and accelerometers, verify the mounting surface is flat, clean, and free of paint layers that can act as a mechanical filter and attenuate high-frequency content.

This GE IS220PVIBH1A is a genuine unit — not aftermarket. It ships with the manufacturer calibration data sheet showing the exact sensitivity, linear range, and frequency response measured at the factory. We also perform a secondary verification on our test bench before shipping. Functional test report included. 48-hour burn-in. 12-month warranty. Ships within 24 hours from Shenzhen.
