Abstract

PURPOSE: To detect accurate, high reliability pressure even if the temperature of a fluid to be measured in high, by forming the diaphragms of a pressure receiving portion in two surfaces.
CONSTITUTION: A liquid sealing disphragm system pressure transducer 1 is particularly used for measuring the pressure of fluids under the conditions of high temperature, low temperature, corrosion, slurry, high viscosity, etc. The pressure of a fluid 12 to be measured is transmitted to primary pressure transmission media sealed in chambers 27, 27A through the diaphragms 22, 22A of a pressure receiving portion 2. Pressure transmitted to the primary pressure transmission media is transmitted to a secondary pressure transmission medium filled in a chamber 28 through a diaphragm 26 of a pressure transmission element 3 at the meter side. When the temperature of the fluid to be measured is high, the primary pressure transmission media expand due to temperature, but the quantities of the allowable expansion of the diaphragms 22, 22A increase because the chambers 27 and 27A are communicated, thus forming no deformation and no failure of the diaphragms 22, 22A, then allowing the detection of accurate, high reliability pressure.
