Detail:
Instrument by the measurement system (including joint, a corrugated diaphragm box, etc.), transmission (including pull rod mechanism gears), indicating components (including pointer and dial) and the housing (including a case, lining ring and watch glass) composed of. The working principle of the instrument is based on the pressure of the corrugated film box in the measured medium, the free end of the corresponding elastic deformation, and then through the gear transmission mechanism of the transmission and amplification, by fixed on the axis of the needle will be measured value on the disc. There are zero adjustment device, can easily adjust the zero.
The measuring range of the pressure gauge of the film box is in -80~60000Pa, but according to the different pressure range, the pressure gauge is recommended for the disc type film box. If the pressure is -80Pa, the pressure gauge is recommended.
