Role Context

Accurate instrumentation allows plant operators to monitor process conditions, control equipment safely and respond to abnormal situations before production or asset integrity is affected. Even a minor fault involving a transmitter, control element or protective device can produce unreliable readings, interrupt a control loop or contribute to an unplanned plant trip.
