Abstract:
An electronic pressure sensing device comprising:a pressure sensing/transmitter module including a base, a pressure sensor having first and second opposed fluid pressure sensing elements, said pressure sensor being immovably mounted relative to said base, and first and second fluid inlet ports immovably attached relative to said base, said first and second inlet port being in closed fluid communication respectively with said first and second sensing elements to supply respective first and second fluids under pressure to the first and second sensing element, a plurality of different adaptors each of which is used for a different application, each said adaptor having first and second fluid outlet ports for connection to the first and second inlet ports of the module, and a coupling mechanism whereby said different adaptors are each configured to be selected and coupled to the base of said module with the first and second outlet ports fluidly connected to the first and second inlet ports, each said different adaptor being further configured for connection to a different configuration of a pressure fluid supply to feed at least a first associated fluid under pressure in the fluid supply to the first inlet port on the module whereby the first fluid under pressure is communicated to said first sensing element associated with said first inlet port, an electronic means provided on said base for interpreting and transmitting values of fluid pressures sensed by the first and second sensing elements.
