Once we get down to the root cause of the failures, in almost every case it’s a situation where the specific sensors are being applied in a manner which all but guarantees premature failure.

Other sensors are specifically designed to meet particular challenges of the application environment and as a result may carry a higher initial price.
Some things to think about when choosing a sensor for a new application:
