Capacitive sensors display a capacitance change when pressure is applied to the diaphragm creating an oscillator frequency. Working principle of Diaphragm Pressure Gauge. A capillary tube is commonly used to connect the diaphragm seal remote with the pressure instrument. When placed in the vagina, usually associated with the spermicide (placed in its concave part), the diaphragm occludes the external orifice of the cervix, making it difficult to ascend spermatozoa that have been released into the vagina through intercourse and its arrival to the ovum, thus fertilization. A vented gauge pressure transmitter for example allows the outside air pressure to be exposed to the negative side of the pressure sensing diaphragm, via a vented cable or a hole on the side of the device, so that it always measures the pressure referred to ambient barometric pressure. Pressure gauges are devices used to measure pressure, all pressure gauges have their own sensing element, which senses the value of the measured quantity. diaphragm is typically below the crown of the arch causing it to under-register the applied pressure. When a medium exerts pressure, the diaphragm bends, altering the cross-sectional area of the piezoresistive elements and leading to a change in their electrical resistance. They can withstand over pressure and hence they are safe to be used. However, this characteristic is related to corresponding standards for quality and tolerances of the diaphragm materials. Both types of valves have advantages and disadvantages. For Bourdon tubes, only stainless steel and Monel are typically suitable.
