Description：

Gas and steam turbines can produce temperatures hotenough to damage or destroy conventional proximity probes.The 3300 High Temperature Proximity System (HTPS) isdesigned to withstand the extreme temperatures foundinside gas turbines, steam turbines and other types ofrotating machinery. The HTPS measures vibration, thrustposition, differential expansion and other parameters insidethe hot areas of these machines. High temperatureinstallations include:

Near a labyrinth seal in steam turbines

Differential expansion in steam turbines

When probe cables are routed through struts thatsupport the bearing housing of a gas turbine

When probe cables are routed out through the exhaustpath of a gas turbine

Monitoring a troublesome bearing in a hightemperature area

Mode shape analysis at the mid-span location onsteam and gas turbines for online machinerydiagnostics

Interstage radial and axial seal clearancemeasurements at the mid-span location of multi-stage steam turbines to minimize seal rubs

Most hot bearing locations that can destroyconventional proximity probes
