记忆型压力表Memory pressure gauge
备选项代码 Options PJY
简 介
◆ 记忆型压力表是由原型号压力表与一个记忆装置配接
组成。
◆ 记忆型压力表的压力指针在随着被测介质压力增大而升高
的同时也带动记忆表针的上升，当随着被测介质压力减少
压力指针下降时，记忆表针仍留在原位。
◆ 记忆型压力表的特点是可以在无人的情况下，如实记录下
测量现场所发生的压力值。
◆ 记忆装置适配于多种型号压力表上，要求压力表的测量范
围大于0.16MPa,且非耐震型。
◆ 不同型号的压力表通过记忆装置配装组成不同型号的记忆
压力表，型号标为压力表型加上备选项代码“PJY”，如
YTFJ-100，防腐不锈钢记忆压力表：YTF-100. AO-PJY
( YTFJ-100)，普通轴向安装记忆压力表Y-050. ZO-PJY
(YJ50Z)等。
◆ 转动仪表玻璃中间记忆装置旋钮，可随时将记忆表针调至
零位。
Brief Introduction
◆ Recording type pressure gauges are composed of a
pressure gauge and a recording device.
◆ The recording pointer is carried by the pointer and
left at the maximum pressure reached.
◆ The memory pointer is pushed up while the medium
pressure increasing, but it will not move when the
pressure decreasing.
◆ Memory device is applicable on non-fillable pressure
gauges with range above 0.16 MPa.
◆ The pressure gauge in differential types fixes with the
orientation to form different Orientation pressure gauge
which adds a code “PJY”. For example the
YTF-100. AO-PJY(YTFJ-100) is Stainless Steel
Corosion-proof memory pressure gauge, and the
Y-050. ZO-PJY(YJ50Z) is General Bottom installation
mounting Memory pressure gauge.
◆ Recording pointer is adjustable from the knob on outside
window.
