定位型压力表

备选项代码 Options PDW
Orientation pressure gauge

简 介
◆ 定位型压力表由一个各种外径的压力表与一个定位装置配
接组成，（耐震型压力表除外）。
◆ 不同型号的压力表与定位装置配接可组成不同型号的定位
型压力表，型号标为压力表型加上备选项代码“PDW”，
如YTH-100. AO. 501-PDW (YTFD-100H) 全不锈钢防腐
定位压力表，YE-PDW (YED) 普通膜盒定位微压表等。
◆ 定位型压力表的特点是可以任意调整限定压力，能明显的
标示出有效的工作压力范围，为现场人员起到警示、提示
作用。
◆ 定位装置设有红绿两个指针。绿色指针可表示起始压力位
置，红色指针可表示终止压力位置。也可任选一个设定针，
单独使用。
◆ 转动仪表定位装置外旋钮，可调节红色指针位置，转动定
位装置 中间“－”旋钮可调节绿色指针位置。
（注：绿色指针只能做顺时针调整）

Brief introduction
◆ It includes a pressure gauge of any diameter (except
Vibration-proof pressure gauge) and an orientation device.
◆ The pressure gauge in differential types fixes with the
orientation to form different Orientation pressure gauge
which adds a code “PDW”. For example the YTH-100.
AO. 501-PDW is All Stainless Steel vibration-proof orientation
pressure gauge, and the YE-PDW(YED) is General
Capsule Orientation pressure gauge.
◆ It could be adjusted of the limit pressure and could be
indicated of the effective pressure scope to make a
warning to the users.
◆ It has 2 pointers which are red and green. The green
pointer could show the start point and the red one could
show the finish point. In addition, it could be used
separately.
◆ Turn the botton out of the orientation device can adjust
the red pointer position, and the “-” botton can change
the green pointer position. (Note: The green pointer can
be deasil adjusted.)
