FIELD: measurement and testing technology; pressure indicating devices. ^ SUBSTANCE: proposed pressure indicator includes pressure delivery branch pipe, pipe union of force creating mechanism which sets motion converter in motion causing rotation of shaft whose axis passes through intersection of optical axes of disk-shaped optical plate at natural polarization. Directrix lenses of optical radiation source and optical signal receiving lenses fix deviation of plate axes. Signals from receiving lenses are transmitted via optics fiber cable to analyzer, photo-detector and then to recording equipment. ^ EFFECT: enhanced accuracy of measurement; extended field of application. ^ 2 dwg |
