摘要
FIELD: recording and testing thermophysical parameters. SUBSTANCE: sensor has a mandrel, fluid-tight tube mounted on the mandrel with the aid of a threaded connection. The inner portion of tube is provided with heat-receiving ribs, and outer one is provided with heat dissipation ribs. The sensor furthermore has a folded grip located within the tube, 1/3 of grid volume being filled with a cooling agent e.g. with freon; nuts mounted on the tube outer side for tightening insulating rings. There are specimens (split rings) with thermocouple wires to be investigated interposed between the rings. The terminals of thermocouple wires are disposed in spline grooves and connected to instrumentation situated on the shelf of a bench. The latter is made in the form of a shot-blasting plant with a working chamber. A screen of a set of circular elements of the sensor is provided with a window which is determined remotely exterior of the working chamber. EFFECT: enhanced reliability. 2 cl, 3 dwg
