INLET ASSEMBLY OF FLOOR-MOUNTED CHAMBER

摘要

FIELD: measurement equipment. ^ SUBSTANCE: invention refers to instrumentation, namely to devices for contact-free temperature measurement of axle boxes of rolling-stock of railways. Inlet assembly of floor-mounted chamber includes the casing attached to the housing of floor-mounted chamber, inside which a gate is installed with possibility of being turned and equipped with calibration elements of measurement channel of floor-mounted chamber. External and protective openings respectively are made in the casing and housing of floor-mounted chamber. Gate is made in the form of a ball from waterproof material with through cylindrical hole. Ball rotation axis is located eccentrically to its centre and perpendicular to axis of cylindrical hole. External opening of casing is round and has an edge from waterproof material and is arranged coaxially to protective opening of the housing. In protective opening of the housing there installed is plate from abrasion-resistant material for example leucosapphire. Gate is equipped with cleaning brushes. ^ EFFECT: increasing scheduled maintenance period of floor-mounted chambers with simultaneous reduction of background illumination of measurement channel of floor-mounted chamber. ^ 2 dwg
