Fluidic pressure gauge including mechanical-electrical transducer - contains membrane with semiconductor which is connected without system depressurisation

摘要

The device is for measuring the pressure of a fluidic system and has a port via which it can be connected to the system without depressurisation. It is a mechanical-electrical transducer which can be rapidly attached to and detached from the fluidic system without affecting system press. It produces an accurate electrical signal directly proportional to the press. An electrical measurement amplifier and measurement cell are combined in a single housing with a measurement coupling consisting of an adapter and connector. The cell contains a membrane acting on a semiconductor element.
