Product manual
YD33 piezoelectric velocity sensor
Velocity sensing, constant-current requirements and mechanical configuration options.
On this page
The printed ordering formula contains only A and B, but its table also defines C for cable length. Confirm the complete order code. The unrelated metadata title is not used as a product model.
Velocity measurement
YD33 uses the direct piezoelectric effect and an internal precision integration circuit to measure absolute machine vibration velocity. The source permits vertical, horizontal or other mounting angles. It describes vibration amplitude, severity and velocity measurement.
The source mentions replacement applications for Bently 330500 and Shinkawa CV861. It does not establish universal mechanical, electrical or certification interchangeability; verify the actual interface and measurement requirements of any replacement.

Mounting and cable options
The table defines A01 = M5 × 0.8, A02 = M8 × 1.25 and A03 = 1/4–28 mounting threads. B00 specifies direct leads, K denotes armor and B01 specifies a circular connector. Cable field C gives 01 = 1 m, 02 = 2 m and 03 = 3 m, with further lengths indicated.
Because C is absent from the printed main formula YD33-A-B, have the complete configuration confirmed before using the code for an order.
