  • Patent number: 6543293
    Abstract: A differential and absolute transducer are secured to a Pyrex glass header by means of a glass metal frit or other suitable interface. One of the sensors measures absolute pressure and the sensor is a sealed cavity, while the other sensor is designed to measure differential pressure and the sensor is an aperture which permits the pressure media to reach both sides of the sensor. The header itself has a through hole connected to a tube over which the differential sensor is affixed. The Pyrex glass is chosen to match the coefficient expansion of the sensors. The header in turn is attached to the tubular member provided with a fitting such that static pressure can be applied to both sensors simultaneously. At the other end of the tubular member, there is provided another fitting attached to the tube in the header through which the total pressure can be applied to the differential sensor, thus permitting the measurement of the difference between the total pressure and the static pressure.

  • Patent number: 6543294
    Abstract: A pressure indicator according to the present invention monitors the pressure of the fluid in a vessel. One embodiment of the present invention comprises a closed pressurized gas volume behind a dimpled metal diaphragm. In normal operation, the force of the fluid pressure acting on the external surface of the diaphragm overcomes the force of the gas pressure acting on the internal surface of the diaphragm to hold the diaphragm in a concave geometry. In the event of a sufficient loss of fluid pressure, the force of the gas pressure acting on the internal surface of the diaphragm will overcome the force of the fluid pressure acting on the external surface of the diaphragm, thereby moving the diaphragm into a convex geometry. A viewing window disposed in the side of the vessel can be used to view the pressure indicator and determine the shape of the indicator diaphragm.
