压力显控器使用说明书
Operation Instruction of the Pressure Control Monitor
一、特性（Characteristic）:
压力显控器 ( 以下简称仪表 ) 是在受压时，借助于弹性元件的位移同时进行压力指示和控制的新型自控仪表，由于采用了双重弹性元件分别进行压力指示和控制，因而其精度大幅度提高，同时具有结构合理，控制精度高、稳定可靠、抗震性优越。触点容量大，使用安装方便，可以进行现场调整等优点。
The pressure control monitor (hereafter refers to as the instrument) is a new kind of automatic control instrument that carries out the pressure indication and the control simultaneously with the aid of the displacement of elastic elements under pressure. Since it adopts the dual elastic elements to carry out the pressure indication and the control respectively, its precision rises substantially. At the same time, it has many advantages such as reasonable structure, high control precision, steady reliable, superior anti-seismic performance and large contact capacity, convenient to use and install as well as adjustable on-the-spot.
二、用途（Usage）:
本仪表适用于对无爆炸危险的非结晶和凝固的无腐蚀性介质压力进行一位或二位式控制。
This instrument is suitable for one or two type control to the amorphous substance with no explosion hazard and the coagulate medium without corrosiveness.

9. 使用环境条件：‐40 ― + 60℃相对温度不大于85%(Operating ambient conditions: ‐40 ― + 60℃.The relative temperature is not bigger than 85%.)
四、结构原理(Structural principle):
仪表由弹性元件，控制机构、调整机构、指示装置，表壳及接线盒等组成。
其工作原理是：在介质压力作用下，弹簧管末断产生位移，当压力达到所设定的控制值时，推动微动开关产生瞬间开关动作，使控制系统中的电路得以通断切换，达到自动控制或发出信号的目的。
The instrument is composed of elastic element, control mechanism, adjusting mechanism, indicating device, watch case and wiring box and so on.
Its working principle is: Under the medium pressure, the spring tube terminal produces displacement. When pressure reaches the control value set, the jogging switch is promoted to produce instant switch movement. This makes the electric circuit in control system on-and-off so that the purpose of automatic control or sending out the signal is reached.
五、使用与调整(Use and adjustment):
1. 设定值调整(Setting value adjustment):
（一）将仪表和精密压力表（可用自身的压力表）连接在压力校验台上，然后按下图接通电源：
Connect the instrument and the precise manometer (your own manometer available) on the pressure checking table. Then connect the power source according to the following drawing:
所用材料(Materials to be used)：1.5V电池两节（two 1.5V batteries）3V灯泡二个（two 3V light bulbs）
（二）升压，将螺丝刀插入调整窗孔内，通过旋拧调整螺钉进行设定值调整，当指示灯产生瞬间亮或灭时，其指针指示的压力值应正好为设定值。
Raise the pressure and insert the screwdriver to the adjustment window hole. Adjust the setting value by turning and twisting the adjusting screw. When indicator light produces instant bright or extinguishes, the pressure value that the indicator indicated should happen to be the setting value.
2. 现场调整（Adjustment on-the-spot）:
通过设定值调整，将仪表装机后或在使用中，若示值偏离设定值，利用仪表的指示装置进行现场调整。
After the setting value is adjusted and the instrument is packed, or when the instrument is in use, if the indicating value deviates the setting value, the instrument can be adjusted on-the-spot by using its indicating device.
3. 仪表的选用（Instrument selection）：
选用仪表时，应按其使用的大压力值再加三分之一进行计算选用。
The instrument should be chosen by calculating the maximum value of its use plus 1/3 of this value.
4. 仪表在使用过程中，应经常保持干燥、洁净，并定期进行检修，以确保其准确，可靠地工作。
In the process of using, the instrument should be kept dry and clean frequently, and should be overhauled regularly so as to ensure that it works accurately and reliably.
