Chemical Sealed Pressure Gauge

Chemical Sealed Pressure Gauge

chemical sealed pressure gauge
Diaphragm sealed gauge commonly known as "chemical seal" gauge are designed and recommended to isolate the measuring system of a pressure gauge from corrosive, pasty or dangerous fluid depending on the viceosity, pressure, temperature, solidification of a particular process medium.

The diaphragm seal has been filled under vacuum with the transmitting liquid, the pressure gauge/diaphragm seal assembly must never be dismantled.

A carefully designed corrogated diaphragm is used to achieve maximum flexibility and linearity with sufficient stroke to provide the displacement needed to produce full deflection of the sensing element.

The diaphragm is argon arc welded to the top chamber to ensure a perfect selling "No LEAK". In some cases the diaphragm is coated OR lined with a second membrane (teflon). The welded construction facilitates removal of the gauge for repair/service without process shut down.

The displacement of the diaphragm is transmitted to the bourdon sensing element, through solidly filled liquid having low cubical expansion with greater temperature stability.

The gauge indicator is either directly fitted with the sealed chamber OR by means of capillary tube, thus permitting easier mounting OR the remote reading of the pressure.
