国产SMT3151型压力变送器是一种将压力变量转换为可传送的标准输出信号的仪表，而且输出信号与压力变量之间有一定的连续函数关系（通常为线性函数）。主要用于工业过程压力参数的测量和控制。仪表人与她们朝夕相处，对他们了如指掌吗？
为了国产SMT3151型压力变送器能够更好的给您的工作带来方便，也为了国产SMT3151型压力变送器能够使用的更长久，建议您平时使用产品适当的维护和保养是非常必要的，
在就地用毛刷和白布把变送器油渍和灰尘清洁干净，变送器上铭牌应清晰可见。
Clean the oil stain and dust on the transmitter with a brush and white cloth. The nameplate on the transmitter should be clearly visible.
核实变送器的测点名称及测点编号是否与该测点相符。
Verify that the measurement point name and the measurement point number of the transmitter are consistent with the measurement point.
检查变送器端盖密封圈及电缆接头是否齐全。
零部件完整无损、无松动；检查管路无堵塞，接口连接紧固。
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.防止渣滓在导管内沉积。（Prevent dregs from depositing in the tube.
2.导压管应安装在温度波动小的地方。
The pressure guide pipe should be installed in the place where the temperature fluctuation is small
3.首先应当防止国产SMT3151型压力变送器与腐蚀性或过热的介质接触。
First, the SMT3151 pressure transmitter should be prevented from contacting corrosive or overheating media.
4.测量液体压力时，取压口应开在流程管道的侧面，以避免沉积积渣。
When measuring the liquid pressure, the outlet should be opened on the side of the process pipeline to avoid the deposition of slag.
5.测量液体压力时，国产SMT3151型压力变送器的安装位置应避免液体的冲击，以免国产SMT3151型压力变送器过压损坏。
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.接线时，将电缆穿过防水接头或绕性管并拧紧密封螺帽，以防雨水等通过电缆渗漏进变送器壳体内。
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.国产SMT3151型压力变送器测量气体压力时，取压口应开在流程管道顶端，并且国产SMT3151型压力变送器也应安装在流程管道上部，以便积累的液体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.冬季发生冰冻时，如果国产SMT3151型压力变送器安装在室外必须对仪表采取防冻措施，避免引压口内的液体因结冰体积膨胀，导致传感器损失。
