The Valve and Shell Expansion Monitor is designed to provide high reliability for the plant’s most critical rotating machinery.

This 1-slot monitor is used with other AMS 6500 monitors to form a complete API 670 machinery protection monitor.

Applications include steam, gas, compressors and water turbines.

The primary function of the Valve and Case Expansion Monitor is to accurately monitor valve position and case expansion.

The main function of the valve and case expansion monitor is to accurately monitor valve position and case expansion and to reliably protect the machinery by comparing parameters with alarm set points, actuated alarms and relays.

Valve position is a measurement of the position of the main steam inlet valve stem, usually displayed as a percentage of opening.

The valve position measurement provides the operator with an indication of the current load on the turbine.

Casing expansion monitoring typically consists of two inductive displacement transducers (or LVDTs) mounted axially, parallel to the shaft, on either side of the turbine casing.

Unlike non-contact eddy current sensors, inductive sensors are contact sensors.

Casing expansion monitoring is important during startup so that the proper expansion rate can be monitored on both sides of the turbine casing.

Because the turbine can slide on the guide rails as it expands, if neither side is free to expand, the turbine will “bend” (housing flex), causing the rotor to collide with the housing.

Channel 1 can be used to measure static values, such as case expansion, as well as dynamic quantities

such as displacement, angle, force, torsion or other physical quantities measured by inductive sensors.

Physical quantities measured by inductive sensors. Channel 2 is used for static measurements and relative displacements (relative to channel 1).

Since the displacement transducer is mounted on the bearing, the monitored parameter is known as shaft relative vibration, i.e. shaft vibration relative to the bearing box.

Shaft relative vibration is an important measurement parameter used for prediction and protection monitoring on all plain bearing machines.

Shaft relative vibration should be selected when the machine housing is large compared to the rotor and the bearing housing does not vibrate between the zero speed of the machine and the production state speed.

Absolute shaft vibration is sometimes selected when the bearing housing and rotor are relatively close in mass, when the bearing housing is more likely to vibrate and affect the relative shaft reading.
