The transducers in this category measure changes in machine case positions as they expand or contract, rotary or linear position of control valves, or wicket gate position on hydroelectric turbines. They are typically used in conjunction with other transducers as part of a Turbine Supervisory Instrumentation ( TSI) package, designed to monitor all critical machinery parameters on large steam, gas, or hydraulic turbines used in power generation applications.
