Pay Peanuts, Get Monkey

Vibration sensor reliability is important for all customers. I am sure everyone is familiar with the term GIGO which stands for Garbage In, Garbage Out.


Whether you are using the vibration sensor for data collection for the purpose of analysis or monitoring a machine 24/7 you would want a sensor that is reliable with a certain quality built that you can rely on and trust in.


Why would vibration sensor reliability be important?


1) Quality of data collected is important. More than ever today when the data collected is increasingly used to train AI-based software. You would want to have accurate data as it affects the predictive power of the algorithm you use to run the condition monitoring software.


If you are collecting the data for vibration analysis you would want data that will show as close as possible the true measured machine condition. In theory sensors of say 10% sensitivity from different brands should offer the same performance.


However, in practice this is not always the case as the quality of the components used in building the sensor can result in different levels of performance. Anyone can make a claim. You will only really know if this is true in practice when you are actually using the vibration sensor.





2) Your vibration monitoring of a machine can be disrupted by walkie talkie interference so it would pay to select a brand which is not prone to this. I recently attended a meeting in which the customer brought this issue up. This issue has been around for donkey years so I would think that by now it should be a non-issue but I guess certain things never get old.


3) Replacement of a vibration sensor can be costly especially if you are using a model with integral cable. I am not referring to the cost of the vibration sensor here but the cost of manpower to run the cabling not to mention the cost of the downtime and disruption to production schedule.


A bean counter will think that a $500 sensor is expensive (prices of sensors can vary from low to high depending on specifications) but when you consider that the average MTBF for a sensor is 25 years the cost of using the sensor would be $20 per year or $0.05 cents per day. And this is to protect an essential machine that in the event of a sudden breakdown can cost the company $XXX,000 per day (insert your figure here) in lost production.


If the machine were to be a person important to be protected would you pay peanuts to employ an old, out-of-shape, slower reacting bodyguard to protect the VIP? Or would you pay a premium to get a bodyguard that is fit for purpose? I am not against old bodyguards since I am no spring chicken either but it is what it is.


So if you would employ only the best for your VIP, why would you not do the same for your essential, must-die, die-not-never stop machine?


It is a basic fact of business that you get what you pay for and by extension, what you can live with. If you get it right the first time you save yourself some headache later on.
