Pressure transducers using the linear differential transformer

A pressure transducer is described, which uses13; a linear variable differential transformer to sense the13; displacement at the centre of a diaphragm subjected to13; the pressure being measured. Design details of the transducer are given including complete specifications for the differential transformer and the electronic circuit used for indication. The diaphragm of the transducer is changed to get different full scale pressure ranges. The accuracy of the transducer in all ranges is better than + 1 per cent
