I do control systems. Depending on MTBF on the sensors and the safety criticality, I will calculate the number of sensors needed. Then I will tell the customer the #. If the customer says “too expensive” then I will tell the customer to FO. 2 /3 vote on safety critical sensors don’t make it safe. How accurate, precise, critical, .....
OK. Thanks for the info. So you would also be calculating how often the sensors would need to be serviced to maintain the desired level of reliability. Correct?
