PGD-45B-500/500_PGD-45L-30_PGD-45L-60_PGD-45L-100差压表OMEGA

差异。差分范围为***个输入始终处于比另***个更高压力的应用提供***大分辨率。如果***个输入可能高于或低于另***个输入，则应使用双向差分范围。PGD系列由两个独立的波登管构成。相对的波登管与单个小齿轮相连，小齿轮转动指针，直接读取压力读数。通过使用两个独立的波登管，压力表可以处理任何***个或两个端口上的液体或气体。大的4.5英寸表盘使读数压力更容易。每个仪表都配有***个测微计调整装置，用于重新调零仪表。仪表有位于较低位置（6点钟）或后部的端口，用于面板安装。

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.
