A differential-rigidity transmitter adapted to produce a sign proportional to a technique variable consisting of bypass cost in a line carrying out fluid or the point of liquid in a tank, the technique fluid being at a temperature markedly at variance with ambient temperature. The transmitter is constituted by using intense and occasional rigidity sensors that are coupled to the rigidity beam of a rigidity stability transducer so as that the beam knows the version between sensed intense and occasional pressures derived from the technique variable, the transducer being uncovered to ambient temperature. each and every sensor is constituted by using a housing having a properly therein lined by using a sensing diaphragm and an insert seated interior the properly, the face of the insert being spaced from the diaphragm to define a fill chamber containing hydraulic fluid, the sensor diaphragm being uncovered to the technique liquid, wherein warmth pass occurs between the liquid and the hydraulic fluid. The insert is formed of a metallic having a low coefficient of enlargement relative to the fabric of the housing wherein changes in temperature produce variations interior the size of the housing relative to that of the insert and supply upward push to variations interior the quantity of the fill chamber to an quantity compen
