Increase uptime by reducing systematic failure risk
Process manufacturers can take clear steps to reduce systematic instrumentation failures
Systematic failures of process instrumentation can be reduced by thoroughly understanding the application, sensing elements, logic solver, final element, material selection, and prior use experience. Risk reduction starts with careful supplier selection, and continues throughout design, installation, commissioning, operation and maintenance.
Random versus systematic failure
To reduce the impact of random failure, maintenance procedures employ proof testing throughout equipment lifecycles, with the hope of discovering fault risks and addressing them prior to failure. Systematic failure — which refers to pre-existing problems caused by faulty equipment design, manufacturing processes, material specification, and/or device installation — is almost entirely avoidable through careful engineering.
