國產SMT3151型壓力變送器是一種將壓力變量轉換為可傳送的標準輸出信號的儀表，而且輸出信號與壓力變量之間有一定的連續函數關系（通常為線性函數）。主要用于工業過程壓力參數的測量和控制。儀表人與她們朝夕相處，對他們了如指掌嗎？
為了國產SMT3151型壓力變送器能夠更好的給您的工作帶來方便，也為了國產SMT3151型壓力變送器能夠使用的更*，建議您平時使用產品適當的維護和保養是非常必要的，
在就地用毛刷和白布把變送器油漬和灰塵清潔干凈，變送器上銘牌應清晰可見。
Clean the oil stain and dust on the transmitter with a brush and white cloth. The nameplate on the transmitter should be clearly visible.
核實變送器的測點名稱及測點編號是否與該測點相符。
Verify that the measurement point name and the measurement point number of the transmitter are consistent with the measurement point.
檢查變送器端蓋密封圈及電纜接頭是否齊全。
零部件完整無損、無松動；檢查管路無堵塞，接口連接緊固。
Check whether the end cover seal ring and cable connector of the transmitter are complete.
Parts and components intact, no loose;Check that the pipeline is not blocked and the interface is tightly connected.
1.防止渣滓在導管內沉積。（Prevent dregs from depositing in the tube.
2.導壓管應安裝在溫度波動小的地方。
The pressure guide pipe should be installed in the place where the temperature fluctuation is small
3.首先應當防止國產SMT3151型壓力變送器與腐蝕性或過熱的介質接觸。
First, the SMT3151 pressure transmitter should be prevented from contacting corrosive or overheating media.
4.測量液體壓力時，取壓口應開在流程管道的側面，以避免沉積積渣。
When measuring the liquid pressure, the outlet should be opened on the side of the process pipeline to avoid the deposition of slag.
5.測量液體壓力時，國產SMT3151型壓力變送器的安裝位置應避免液體的沖擊，以免國產SMT3151型壓力變送器過壓損壞。
When measuring the liquid pressure, the installation position of SMT3151 pressure transmitter should avoid the impact of the liquid, so as to avoid the overpressure damage of SMT3151 pressure transmitter.
6.接線時，將電纜穿過防水接頭或繞性管并擰緊密封螺帽，以防雨水等通過電纜滲漏進變送器殼體內。
When wiring, pass the cable through the waterproof joint or the winding pipe and tighten the sealing nut to prevent rain water and other leakage into the transmitter shell through the cable.

7.國產SMT3151型壓力變送器測量氣體壓力時，取壓口應開在流程管道頂端，并且國產SMT3151型壓力變送器也應安裝在流程管道上部，以便積累的液體容易注入流程管道中。
When measuring the gas pressure of the SMT3151 pressure transmitter, the pressure outlet shall be opened at the top of the process pipeline, and the pressure transmitter of SMT3151 shall be installed at the top of the process pipeline, so that the accumulated liquid can be easily injected into the process pipeline
8.冬季發生冰凍時，如果國產SMT3151型壓力變送器安裝在室外必須對儀表采取防凍措施，避免引壓口內的液體因結冰體積膨脹，導致傳感器損失。
