Long Description
The Valve and Case Expansion Monitor is designed for high reliability for the plant's most critical rotating machinery. This 1-slot monitor is used together with other AMS 6500 monitors to build a complete API 670 machinery protection monitor. Applications include steam, gas, compressors and hydro turbomachinery. The main functionality of the Valve and Case Expansion Monitor is to accurately monitor valve position and case expansion and reliably protect machinery by comparing parameters against alarm setpoints, driving alarms and relays. Valve position is a measurement of the main steam inlet valve stem position normally displayed in percent open. The valve position measurement provides the operator with an indication of the current load on the turbine. Case expansion monitoring usually consists of two inductive displacement sensor (or LVDT’s) mounted in the axial direction, parallel to the shaft, and on each side of the turbine case. Unlike the eddy current sensor which is a non-contact sensor, the inductive sensor is a contact sensor. |  |
