Hope you are well.
I have a quick query please which is somewhat urgent.
I have been asked by a Client whether a MEMS vibration sensor (triaxial) once deployed ever needs to;
1: Be recalibrated after being used for some time? and
2: Have a verification procedure for temperature and vibration checks in the future?
The Client is considering to enter into a Contract for Wireless Sensors (MEMS based) and whilst they appreciate these Sensors are calibrated before they leave the factory, whether ongoing recalibration / certification is required.
Any guidelines or guidance welcomed.
