Hi everyone,

We have a project in a refinery company and we need a vibration measuring system consisting of a sensor mounted on a case fan assembly and a vibration transmitter that is mounted outside of the cooling fan tower. It should transmit the vibration signal to the control room for monitoring, alarm and shut down.

Can anybody suggest any manufacturer in Europe or US?

 

Hi,

I am not sure about the availability I have used Bently Nevada vibration probes for the same purpose, but its very costly. It depends on your application. Even for 8 stage compressors the same has been used. The system consist of sensor cable, proximitor and a Input card/Controller.

 

Contact Bentley Nevada, or Schenk.

 

There are numerous vendors of condition monitoring systems.

GE owns the former Bently-Nevada. http://www.bently.com

Curtis-Wright owns Swantech. http://www.swantech.com

Emerson has just introduced WirelessHART based vibration transmitters and corrosion transmitters. http://www.emersonprocess.com

Honeywell has similar devices for their own OneWireless network. http://psweb.honeywell.com

Rockwell Automation's Allen-Bradley product line produces them. http://www.rockwellautomation.com

And there are many more.

Searching google for the string "vibration monitoring" returns 2.34 million results.

Searching google for the string "condition monitoring" returns 32.5 million results.

Apparently there are lots of people just waiting for you to call them.

Good luck, and let us know what you did...

Bentley-Nevada has a system, or do it inside of an existing PLC.

Make sure all the sensors are API approved before making any decision.

 

Dear Marzie, What do you intend to measure? Do you already have a condition monitoring program in place?

The answer to the first question could be vibration in terms of displacement, velocity or acceleration and the other numerous variations on the theme. More in-depth analysis involves recording of spectra at one or more points on the machine and then FFT the signal to get frequency components and their magnitudes.

If the answer to the second question is in the neagative, then you should get in touch with the big-boys who earn their bread and butter from this line of work.
