外型结构及安装方式Structure and installation
压力变送器应尽量安装在温度梯度和温度波动小的测压点上，同时还要避免考虑到振动和冲击的影响。变送器应直接安装在测量点上，但强腐蚀性的或过热的介质不应与变送器直接接触，需配装化学密封组件或散热器等进行隔离保护，再把取压口介质压力传输到变送器。
It is better to be installed to the place with little temperature fluctuate and avoid the vibration and concussion.To make sure the sealing of the connection part, it is better to wrap the adhesive tape before fixing the transmitter.It should be installed on the measuring point but not to touch the medium with strong corrupt and high temperature. It is better to make a transition by a special pipe.

系统连接及调试Connection and debugging
变送器在测量系统中的连接见图，建议电源电压Us 选用24V。
二次仪表中采样电阻（负载电阻）RL 的阻值选用250 Ω。如果Us 和RL 选用别的数值，那么RL 值不能超过由公式RL= 计算得到的数值。
See the chart as follow. Suggest the supply Us to be 24V.
The connected gauge should be RL=250Ω。If you choose other date for Us and RL，the RL can not exceedRL= .Use wires to seal the holes on the sides of the transmitter or install the signal wire to the holes and fix by tight nut. The hole without used should be sealed.
出厂前压力变送器已按订货要求调试合格，用户无需再做调整。长时间使用后如需重新标定，可分别调整“调零电位器”和“调量程电位器”。压力量程的下限值对应于4mA，上限值对应20mA. （ Z- 调零电位器 S-调量程电位器）
The transmitter has been debugged as the customer’s request, no need to debug again. After long time of using, if needed, it can be debugged by adjust“ Zero electric device” and“ Range electric device”. The down limit of the range should be corresponding with 4mA，and up limit will be with 20mA. (Z- Zero electric device, SRange electric device)
安 装Installation notes
1. 直接安装在测量点上（任意角度）。
Direct install to the measuring point（any angles）.
2. 尽量安装在温度梯度与温度波动小的测压点上，同时避免强振动和冲击。
It is better to be with less temperature fluctuation and avoid the strong vibration.
3. 室外安装时，尽可能放置于保护盒内，避免阳光直射和雨淋，以保持变送器性能稳定和延长使用寿命。
If it is needed to install outside of the house, it is better to put it into a protect case to avoid sun and rain.
4. 测量蒸汽或其它高温介质时，注意不要使变送器的工作温度超限。必要时，请安装散热器或其它冷却装置连接。
While measuring the high temperature mediums, please do not exceed the temperature limitation. If necessary, fit it with cooling devices.
5. 安装时应在变送器和介质之间加装压力截止阀，以便检修和防止取压口堵塞而影响测量精度。在压力波动范围大的场合还应加装阻尼器或压力缓冲装置。
Add pressure cut-off valve between the transmitter and the medium and add the dampers if the pressure changes a lot.
