Today’s petrochemical and process industries increasingly depend on higher levels of automation, which in turn require enhanced monitoring and control of valve position and operational readiness. In the past, many valves were deployed without any monitoring devices; however, today’s processes require feedback not only for valve position monitoring but also for remote or automated control of valve actuators. In addition to new valves with feedback installed on projects, existing valves are being retrofitted with feedback devices or upgraded with more modern feedback technology. One of those is Magnetostrictive Linear Displacement Transducers (MLDTs).
