PGD-45L-200_PGD-45L-50/50差压表OMEGA
PGD-45L-200_PGD-45L-50/50差压表OMEGA
重型结构
双强度抗碎玻璃
2-1-2%ANSI A级精度
欧米茄的PGD系列压差表是坚固的工业仪表，显示两个输入连接之间的差异。差分量程为一个输入始终处于高于另一个输入的应用提供最大分辨率。如果一个输入可以高于或低于另一个，则应使用双向差分范围。PGD系列由两个独立的波登管构成。相对的波登管与一个小齿轮相连，小齿轮转动指针以获得直接的压力读数。通过使用两个独立的波登管，压力表可以处理任何一个或两个端口上的液体或气体。4.5英寸的大表盘使读数压力更容易。每个仪表都配有千分尺调整装置，用于重新调零仪表。压力表的端口位于下部（6点钟）位置或后部，用于安装面板。

2-1-2% ANSI Grade A Accuracy
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.
