DEVICE FOR MEASURING TEAT PRESSURE ON TEAT Russian patent published in 2019 - IPC A01J7/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular to devices for measuring teat pressure on teats during production, diagnosing technical condition and maintenance of milking machines. Device for measuring teat rubber pressure on teat includes a measuring unit, which comprises a housing, an artificial teat made in the form of an elastic shell, which inner cavity is connected to atmosphere through valve, artificial teat tare unit containing chamber with nut, pressure gauge, manual pump, power supply unit, valve electric drive, negative pressure sensor with valve control electric drive output connected to teat cup wall inter-wall chamber inlet. Inner cavity of teat is connected with pressure sensor, which is located on housing of measuring unit and is connected to measuring instrument by means of measuring circuit. Measuring circuit is tuned so that the level of the output signal at the pressure in the cavity of the artificial teat equal to zero corresponds to the pressure corresponding to the deformation of the artificial teat.

EFFECT: increased accuracy of measuring pressure of teat liner on teat.
