Abstract:
A visual pressure indicator (100) is provided according to the invention. The visual pressure indicator (100) includes a diaphragm chamber (126), a diaphragm (122) located in and displaceable within the diaphragm chamber (126), a fluid inlet (111) in fluid communication with a first side (124) of the diaphragm (122), wherein fluid pressure introduced via the fluid inlet (111) displaces the diaphragm (122) within the diaphragm chamber (126) and wherein the displacement of the diaphragm (122) is substantially related to the fluid pressure at the fluid inlet (111), and a viewing window (131) in the visual pressure indicator (100), wherein a displacement of the diaphragm (122) is observable through the viewing window (131).
