Structure and installation
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(tǒng)連接及調(diào)試
變送器在測(cè)量系統(tǒng)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(fù)載電阻)R L 的阻值選用250Ω。如果Us和R L 選用別的數(shù)值,那么R L 值不能超過
由公式 R L = 計(jì)算得到的數(shù)值。

出廠前壓力變送器已按訂貨要求調(diào)試合格,用戶無需再做調(diào)整。長(zhǎng)時(shí)間使用后如需重新標(biāo)定,可分別調(diào)整
“調(diào)零電位器”和“調(diào)量程電位器”。壓力量程的下限值對(duì)應(yīng)于 4mA,上限值對(duì)應(yīng) 20mA. ( Z- 調(diào)零電位器 S-

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, S-

安 裝
1. 直接安裝在測(cè)量點(diǎn)上(任意角度)。
2. 盡量安裝在溫度梯度與溫度波動(dòng)小的測(cè)壓點(diǎn)上,同時(shí)避免強(qiáng)振動(dòng)和沖擊。
3. 室外安裝時(shí),盡可能放置于保護(hù)盒內(nèi),避免陽光直射和雨淋,以保持變送器性能穩(wěn)定和延長(zhǎng)使用壽命。
4. 測(cè)量蒸汽或其它高溫介質(zhì)時(shí),注意不要使變送器的工作溫度超限。必要時(shí),請(qǐng)安裝散熱器或其它冷卻裝置連
接。
5. 安裝時(shí)應(yīng)在變送器和介質(zhì)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(cè)量精度。在壓力波動(dòng)范
圍大的場(chǎng)合還應(yīng)加裝阻尼器或壓力緩沖裝置。

Installation notes
1. Direct install to the measuring point(any angles).
2. It is better to be with less temperature fluctuation and avoid the strong vibration.
3. 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. While measuring the high temperature mediums, please do not exceed the temperature limitation. If
necessary, fit it with cooling devices.
5. Add pressure cut-off valve between the transmitter and the medium and add the dampers if the pressure
changes a lot.
Connection and debugging
See the chart as follow. Suggest the supply Us to be 24V.
The connected gauge should be R L =250Ω。If you choose other date for Us and R L ,the R L can not exceed
R L = .
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.
