Specifications and Ordering Information Part Number 141623-01 Rev. C (08/07) Page 1 of 17 Bently Nevada™ Asset Condition Monitoring 3300 High Temperature Proximity System Description 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 midspan location of multi-stage steam turbines to minimize seal rubs • Most hot bearing locations that can destroy conventional proximity probes High temperature transducer with a rugged design The 3300 High Temperature Proximity System can be used for proximity measurements at hot locations with excellent results. Customer benefits include: • Proximity probe with integral hardline cable rated for +350°C (+662°F) continuous service in extreme conditions • 4 mm (160 mils) of linear range for most measurements in the hot sections of the machine • Hermetically-sealed ceramic probe tip seals out moisture and contaminants for added durability • Ceramic tip and stainless steel construction resists heat, moisture and corrosion • Threaded and smooth case styles for various types of probe mounting • Hardline cable available in lengths of 1, 2 and 5 metres for routing cable through hot sections of the machine • 3.94 V/mm (100 mV/mil) signal output compatible with virtually all new and existing Bently Nevada monitors and diagnostic equipment
