About anti-interference ability of digital pressure gauge

As a test and standard instrument, digital pressure gauge is mainly used in various industrial scenes and laboratories.
The laboratory environment is relatively simple and there is no interference. But the industrial site is different, all kinds of interference exist, then the anti-interference ability of the digital pressure gauge is particularly important.
Digital pressure gauges are generally battery-powered, and only the sensor is in contact with the outside world. The sensor is an insulating device. As long as the sensor is sufficiently insulated, there is no more way for the digital pressure gauge to interfere with the digital pressure gauge. However, if the external adapter can be connected, the adapter may introduce surge, electromagnetic interference, power frequency interference and so on. In this way, various interference tests need to be performed when the adapter is connected to this part of the circuit, mainly surge, EFT, static electricity, etc. Do these steps well, and test each anti-interference index can meet the requirements of the national standard, then the anti-interference ability of the digital pressure gauge will be greatly enhanced, and the field use will be more stable.
