What are process sensors? What are process actuators?

Process sensors measure temperature, pressure, level, flow, and other parameters. Process actuators (valves, pumps, heaters, fans, mixers, and others) change a process.

Understand partial-stroke testing

Partial-stroke tests (PSTs) of emergency shutdown (ESD) valves improve safety instrumented system (SIS) performance; monitor these critical valves to ensure the system’s ability to shut a process down in the event of an emergency

Process control sensor types and applications

Taking accurate, reliable measurements of process parameters that matter is the first step to optimizing any control loop. You cannot improve what you do not measure. Process sensors help, including temperature sensors, pressure sensors, level sensors and flow sensors (flow meters).
