'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."
I assume you and customer already know that the existing DAQ digitizes (A/D) the analog signal from the accelerometer. Changing to a wireless accelerometer adds the complexity of DAQ and transmitter within the new accelerometer. So how can the digital receiver send digital to the existing DAQ? You have two bad choices: 1) convert received digital data back to analog signal (DA) and then to DAQ, or 2) replace existing DAQ with wireless components to get digital signal to control room.
Changing from a single axis accelerometer (assumed) to wireless triaxial accelerometer involves some thought besides playing with the signals!
There are systems with wireless DAQ box fed by one or more analog accelerometers connected to box with short wires. Get rid of the existing DAQ box and convert to wireless system at that point.
