Pressure transmitter is a very commonly used product in all instrumentation product categories. Among them, imported pressure transmitters are welcomed by many domestic customers because of their high performance and high quality, and they are also very common in actual use. So what problems should be paid attention to in the daily use of imported pressure transmitters?
The inlet pressure transmitter should be placed in the upper part of the process pipeline during measurement, so that the accumulated liquid can flow into the pipeline naturally, and the transmitter to the AFC should be installed in a place with small temperature fluctuations. When using an imported pressure transmitter to measure steam and other high-temperature media, a muscle-building condenser tube is required to prevent the temperature from becoming too high and causing damage to the instrument.
When imported transmitters work in too low temperature, anti-freezing measures should be taken to prevent damage and damage to the instrument. When measuring liquid pressure, the installation of the product should avoid the occurrence of water hammer, which will cause damage to the instrument. When wiring, pass the cable through the waterproof joint (accessory) or flexible pipe and tighten the sealing nut to prevent rainwater and other leakage through the cable into the transmitter housing.
As long as you pay attention to the above precautions, the use of imported pressure transmitters generally does not cause major problems. It is widely used in many industries such as petroleum, electric power, papermaking, steel, machinery and shipbuilding. For example, in the petroleum industry, it is usually matched with a throttling device to achieve flow measurement and control functions. It is generally used to measure the pressure and liquid level of pipes and storage tanks; it is generally used to measure various chemical liquids and corrosion resistance in the paper industry liquid.
