外型結構及安裝方式Structure and installation
壓力變送器應盡量安裝在溫度梯度和溫度波動小的測壓點上,同時還要避免考慮到振動和沖擊的影響。變送器應直接安裝在測量點上,但強腐蝕性的或過熱的介質不應與變送器直接接觸,需配裝化學密封組件或散熱器等進行隔離保護,再把取壓口介質壓力傳輸到變送器。
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.

系統連接及調試Connection and debugging
變送器在測量系統中的連接見圖,建議電源電壓Us 選用24V。
二次儀表中采樣電阻(負載電阻)RL 的阻值選用250 Ω。如果Us 和RL 選用別的數值,那么RL 值不能超過由公式RL= 計算得到的數值。
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.

出廠前壓力變送器已按訂貨要求調試合格,用戶無需再做調整。長時間使用后如需重新標定,可分別調整“調零電位器”和“調量程電位器”。壓力量程的下限值對應于4mA,上限值對應20mA. ( Z- 調零電位器 S-調量程電位器)
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 裝Installation notes
1. 直接安裝在測量點上(任意角度)。
Direct install to the measuring point(any angles).
2. 盡量安裝在溫度梯度與溫度波動小的測壓點上,同時避免強振動和沖擊。
It is better to be with less temperature fluctuation and avoid the strong vibration.
3. 室外安裝時,盡可能放置于保護盒內,避免陽光直射和雨淋,以保持變送器性能穩定和延長使用壽命。
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. 測量蒸汽或其它高溫介質時,注意不要使變送器的工作溫度超限。必要時,請安裝散熱器或其它冷卻裝置連接。
While measuring the high temperature mediums, please do not exceed the temperature limitation. If necessary, fit it with cooling devices.
5. 安裝時應在變送器和介質之間加裝壓力截止閥,以便檢修和防止取壓口堵塞而影響測量精度。在壓力波動范圍大的場合還應加裝阻尼器或壓力緩沖裝置。
Add pressure cut-off valve between the transmitter and the medium and add the dampers if the pressure changes a lot.
