These long-arm external housing assemblies are typically mounted directly onto the housings of large-diameter hydrodynamic bearings in critical plant equipment, including: large steam and gas turbine housings (where thick insulation blankets require longer probe penetration depths); high-output centrifugal turbo compressors and process exhaust fans; heavy-duty utility boiler feed pumps and reduction gearboxes.
