Brief Introduction

330525-00

 330525 piezoelectric speed sensor, generally connected to the secondary instrument Bentley 1900/65A, BENTLY3500/42MTypical models are 330525-00, 330525-01, 330525-02 and the connecting cable 106765-33 is a rugged version of Bently Nevada's 330500 speed sensor. It has a stainless steel housing, environmental protection connectors, and cable assemblies, and does not require a cabinet for installation. Probes and cable assemblies can be used in wet environments and meet IP-65 and NEMA 4X requirements when installed correctly. The rugged version of the Bently 330500. It has a stainless steel housing, environmental protection connectors, and cable assemblies, and does not require a cabinet for installation. Velomitor® XA and cable assemblies can be used in wet environments and meet IP-65 and NEMA 4X requirements when installed correctly. If the machine is to be protected as a whole by means of box measurements, the usefulness of each measurement should be considered. The most common machine failures (unbalanced, uncentered) occur on the rotor, causing an increase (or at least a change) in the rotor vibration. In order to effectively protect the machine as a whole only by means of chamber measurements, it is necessary that sufficiently large rotor vibrations are faithfully transmitted to the bearing housing or casing or, in more special cases, to the location where the sensor is mounted. In addition, great care must be paid to the installation of the sensor. If not installed properly, it can lead to changes in the amplitude/frequency response of the sensor or to generate false signals that do not characterize the actual vibration of the machine.
