I have been asked to collect shaft and casing data from a motor only, the motor has prox probes fitted (images attached)
Can I collect shaft data from these prox probes with my Commtest vb7? Any help or advice very welcome Mike |
|||
|
Sorry I seem to have got a problem adding attachments is anyone else?
|

For some reason I still cannot attach anything, the prox probes are BN 3300 XL Series Sensor

The VB7 can accept proximity probe signals at 200mV/mill so you should be able to get the measurements you want.
You will need to ensure that all components of the prox probe system are present i.e. probe + extension cable + proximitor and make sure that the probe and extension cable combination are compatible with the proximiter (5m or 7m lengths) The proximitor requires power from a -17 to -24 Vdc source (or thereabouts) which can be supplied by 2 12V batteries connected in series. Obviously, casing and displacement and shaft displacement will not be the same Hope this helps - post more info if you need more help |

Thanks Buzz I have some images but I still cannot add an attachment, after I send the reply I get the following message

Provide -24 volts power between COM and Vt
Measure vibration signal (+ DC gap volts) between OUT and COM |

Many thanks
