FIELD: measuring equipment.
SUBSTANCE: invention relates to measuring equipment, and specifically to devices for measuring weight and force. Elastic element of the sensor is made in the form of a parallelogram from a titanium alloy with two support sites, into which a serially produced strain-gauge module C 05 is built. Measured force, through the rod made integral with the elastic element and fixed in the centre with the end of lever C 05, is transmitted to the lever, which deforms the membrane and the bridge of semiconductor tensoresistors fixed on it. When voltage is applied to the input of the sensor and its load with force (with weight), on the output diagonal of the bridge, an output signal is generated, which is proportional to the measured force.
EFFECT: high noise immunity, accuracy and reliability of the sensor, as well as ease of manufacture.
