330380-90-00 3300 XL 16mm High Temperature Proximitor Sensor

Gas and steam turbines can produce temperatures hot enough to damage or destroy conventional proximity probes. The 3300 High Temperature Proximity System (HTPS) is designed to withstand the extreme temperatures found inside gas turbines, steam turbines and other types of rotating machinery. The HTPS measures vibration, thrust position, differential expansion and other parameters inside 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
• 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 online machinery diagnostics
• Interstage radial and axial seal clearance measurements at the mid-span location of multistage steam turbines to minimize seal rubs
• Most hot bearing locations that can destroy conventional proximity probes
