Gas and steam turbines can produce temperatures hot enough to damage ordestroy conventional proximity probes. The 3300 High Temperature ProximitySystem (HTPS) is designed to withstand the extreme temperatures found insidegas turbines, steam turbines and other types of rotating machinery. The HTPSmeasures vibration, thrust position, differential expansion and other parametersinside the hot areas of these machines. High temperature installations include:
Near a labyrinth seal in steam turbines
Differential expansion in steam turbines
When probe cables are routed through struts that support the bearing housing
of a gas turbine
online machinery diagnostics
When probe cables are routed out through the exhaust path of a gas turbine
Monitoring a troublesome bearing in a high temperature area
Mode shape analysis at the mid-span location on steam and gas turbines for
Interstage radial and axial seal clearance measurements at the mid-span loca-tion of multi-stage steam turbines to minimize seal rubs
Most hot bearing locations that can destroy conventional proximity probes
