Abstract

The transducer 10 is of the type comprising an elastically deformable membrane 21 capable of assuming a number of operating positions, each dependent on the pressure exerted on a surface, positioned during use in contact with the oil whose pressure is to be detected, a rheostat 30 provided with a cursor 37 capable of being inserted in a control circuit of an indicator instrument 51, and a kinematic motion 25 to control the position of cursor 37 as a function of the position assumed by membrane 21; both the rheostat 30 and kinematic motion 25 are housed within a sealed tin-plated compartment 27 delimited by a surface of membrane 21, on the opposite side of which contact with oil occurs. To reduce the effect on indicator 51 due to an increase in temperature in compartment 27, the transducer 10 comprises a thermistor 53 with a negative temperature coefficient NTC arranged in parallel with the resistor 43 of rheostat 30. <IMAGE>
