<p>The invention relates to a micro-manometer with compensation of the errors due to the environment temperature, with electronic display, used in laboratories and in industry for measurements, verifications, testings and calibrations in the fluid pressure field. According to the invention, the micro-manometer comprises a pressure transducer comprising a compensation capsule subassembly (7), which removes the errors due to the environment temperature by that it is mounted to work antagonistically with a measuring capsule (22), so that, at the dilatations thereof, there oppose the dilatations of the subassembly (7), said compensation capsule being fastened to the measuring capsule (22) and to an upper plate (9) of a transducer by means of a nut (8) which, after the initial adjustment, is blocked with an adhesive, and a differential coil (26) is supported, at its lower side, on a bushing (27) and a compression helical spring (28), pre-stressed by another nut (24), placed at the upper side of the differential coil (26), which, after the initial adjustment, is sealed, and the differential coil (26) is supplementarily blocked by a threaded peg (25).</p> |
