TEMPERATURE SENSOR Russian patent published in 2010 - IPC F23N5/02 G01K13/02 

FIELD: power industry.

SUBSTANCE: temperature sensor consists of housing (1) with tube thread, is connected to outer tube (2) made from polymer material; inside sensor there installed is metal pin (3), screw device (it is not shown in dwg) for measurement of length of metal pin (3); the latter has adjustment thread (4) in which there installed is single-position damper (5) containing flexible locking element (6), sealing ring (7), adjustment disc (8), housing (1), includes nozzle (9) connected to under-membrane space (10) and nozzle (11) connected to furnace (12) of boiler for out-of-door installation. Pneumatic scheme of temperature sensor with gas shutoff valve and elements of atmospheric gas burner includes the following: gas shutoff valve (13) with membrane device (14); the latter includes comb (13) connected with its nozzles to nozzle of temperature sensor (15), thrust sensor (17), flame scanner (18) with under-membrane cavity (10); at that, comb (15) has jet nozzle (19) connected to delivery gas sensor (20), above-membrane cavity (21) includes jet nozzle (22), spring (23). Pneumatic scheme includes igniter (24), thermal bimetallic plate (25), gas shutoff valve (26), burner (27), furnace (12). All the elements of atmospheric gas burner are connected by means of pipes and pulse tubes.

EFFECT: simplifying the construction, decreasing overall dimensions of axial movement of metal pin.
