FIELD: instrument engineering; measuring of force, pressure temperature and liquid or gas flow rates. SUBSTANCE: proposed device has flexible member with fitted on resistance strain gauge, massive plate with fitted on second resistance strain gauge, bridge circuit, supply source and recording device. Plate and flexible member are made of same material. method comes to measuring force indices by means of resistance strain gauge mounted on flexible member. temperature indices are measured by means of resistance strain gauge installed on massive plate. EFFECT: enlarged operating capabilities of circuit, increased longevity and enhanced fire safety of device. 3 cl, 1 dwg
