PGD-45B-500/500_PGD-45L-30_PGD-45L-60_PGD-45L-100差壓表OMEGA

差異。差分范圍為***個輸入始終處于比另***個更高壓力的應用提供***大分辨率。如果***個輸入可能高于或低于另***個輸入，則應使用雙向差分范圍。PGD系列由兩個獨立的波登管構成。相對的波登管與單個小齒輪相連，小齒輪轉(zhuǎn)動指針，直接讀取壓力讀數(shù)。通過使用兩個獨立的波登管，壓力表可以處理任何***個或兩個端口上的液體或氣體。大的4.5英寸表盤使讀數(shù)壓力更容易。每個儀表都配有***個測微計調(diào)整裝置，用于重新調(diào)零儀表。儀表有位于較低位置（6點鐘）或后部的端口，用于面板安裝。

OMEGA’s PGD Series differential pressure gauges are rugged industrial gauges which indicate the difference between two input connections. Differential ranges provide the maximum resolution for applications where one input is always at a higher pressure than the other. In cases where one input can be higher or lower than the other, a bi-directional differential range should be used. The PGD Series is constructed with two independent Bourdon tubes. The opposing Bourdon tubes are linked to a single pinion gear which rotates a pointer for direct pressure readings. By using two independent Bourdon tubes, the gauge can handle liquids or gases on either or both ports. The large 4?" dial makes reading pressure easy. Each gauge is equipped with a micrometer adjustment for rezeroing the gauge. Gauges are available with ports located in the lower (six o’clock) position or in the rear for panel mounting.
