Bently Nevada 330500-07-04 Velomitor piezoelectric velocity sensor is manufactured by Bently Nevada Corporation and is designed to measure the absolute vibration (relative to free space) of a bearing housing, housing or structure.

The 330500 is a special piezoelectric accelerometer that is a solid-state design with embedded electronics.

With solid-state electronics and no moving parts, it is not susceptible to mechanical degradation and wear, and can be mounted vertically, horizontally or at any other angle.
Features:

1. Electrical Sensitivity: With a sensitivity of 3.94mV/mm/s (100 mV/in/s) and an error within ±5%, it can accurately convert vibration velocity signals to electrical signals.
2. Frequency response: In the frequency range of 4.5 Hz to 5 kHz (270 cpm to 300 kcpm), the response error is ±3.0 dB; in the frequency range of 6.0 Hz to 2.5 kHz (360 cpm to 150 kcpm), the response error is ±0.9 dB, which can adapt to vibration measurements of different frequencies.
3. Temperature sensitivity: In the operating temperature range, the typical value of temperature sensitivity is between - 14% and + 7.5%, indicating that it is affected by temperature changes within a certain controllable range.
