Hello Everyone,

I am basically a networking solution designer trying his hands into Vibration Analysis. I have almost negligible knowledge of Vibration Analysis. I am trying to design a Wireless Vibration measurement and monitoring system for a client who has a LAN spread over a radius of  1 KM and who is insisting on using most of his decade old Vibration monitoring system. This decade old Vibration Monitoring System has a Software installed on a desktop in control room. 2nd device in this Setup is an NCA which has been mounted on a wall just outside Control room. This NCA is sort of a mediator between Software and Data Acquisition Device (DAQ) which is mounted on a wall near the motors which are being monitored. On one hand, NCA communicates with software via LAN, and on the other hand, it communicates with DAQ wirelessly via RF communication. DAQ is connected with Sensors via RS 485 connectors and cables. The unique specialty of this DAQ is that it can communicate and receive data from almost all type of Vibration Sensors. Now, the client wants me to convert the wired connection between DAQ and Sensors into a wireless one. Only change he has allowed me is to use Wireless Vibration Sensors. Now, I searched everywhere but I could only find one solution which looks practical and which is listed at "https://www.erbessd-instruments.com/wireless-accelerometer" The product has a combination of a Wireless Vibration Sensor called "Wiser3x" and a Universal receiver. This universal receiver can be connected to any DAQ using RS485 connectors and cables to transfer data. This way, it converts a wired combination of DAQ and Sensors into a wireless solution. Unfortunately, my client is not ready to accept this solution as Erbessd are a competitor for him. I was wondering if anyone is aware of a similar solution  which can be used in similar manner to convert a Wired Vibration Monitoring System into a Wireless one since my client is not allowing me to replace the existing software and DAQ. If yes, than I would greatly appreciate it if you guys can point me to the site (other than erbessd ofcourse). 

Many Thanks,
M K Baisla

I find something strange in this question. First, why such a secret about the existing monitoring system. Second, regarding a competitor... who is your client? The company with production or existing vibration monitoring provider? How could Erbessd be a competitor but some other provider couldn't?
I also can't figure out how Erbessd wireless system (I have some knowledge about it) could be integrated with your existing sensors and DAQ modules. At least you should use Erbessd sensors that way.

Hello Alex,

Thanks for your response. I really appreciate it.

Well, I can't reveal much about my client and project due to confidentiality agreement. Erbessd is a competitor because their dealer in India had also bid for the same project as we did. 

We do not know whether Erbessd Sensor and receiver can be fitted into the existing system of our client or not as we have not verified it. But it is written on their website that the Universal Receiver of Erbessd works with almost every 3rd party system (please look at the attached screen shots from their website) so I am trusting their word on it. Additionally, I am only talking about their "Wireless Sensors + Universal Receiver". I am not talking about the rest of their system. 

Hope that helps. 


Many Thanks,
M K Baisla.

We are consultants since 1972 vibration, electronics, software etc. so give us a confidential request and we will evaluate and quote, we have no connection to Erbessed or any other whatsoever. We make and develop sensors, systems, vibrometers, analyzers, Android apps since the first vibrometer by my father 1952 and deliver world wide as supplier to Alfa Laval, Valmet, Volvo Cars, Volvo Trucks, Scania, Volvo Penta, IRD India etc.

Manoj101 as you can see from your photo attached in that case you need Erbessd Wiser accelerometer it doesn't work the other way. So the first part of the chain is their sensor.
I also think you will hardly find a solution here without any information about the existing system. Good luck anyway.

Why does the first post on this thread read like one of those made up product placement news stories?

Or maybe it's just me?

It seems like a legit question to me. He just seems like he is a bit out of his depth, as he explained.

Alex, as I understand, he is allowed to replace the sensors, just not the DAQ system. If he couldn't replace the sensors, good effing luck with that. however, I'm unsure if there exists a system from the nearly 100 competing wireless accelerometer systems that has a gateway that can output analog signals to a DAQ.

Well he didn't email me anyway so he is on his own..... Good Luck.

I'm not sure I fully understand the challenge at hand, but PhoenixContact has a range of products to replace wired connections from a sensor to another device for various analog and serial communication standards:

I started to make a detailed response, but I scrapped it in favor of waiting for more information from Manoj101.

I am confused about what the NCA is and does. I am confused what accelerometers currently use a RS 485 connector and cables. It would be nice to know whether the current accelerometers provide a wide-band analog signal or just a voltage or current proportional to overall vibration level. If there is already a wireless connection between NCA and DAQ, then leave the accelerometers wired to the DAQ and add DAQs as needed.
