1. ifm sensor PN2071 pressure up, sensor output can not go up in this case, first should check whether the pressure interface is leaking or blocked, if not, check the wiring method and check the power supply, if the power supply is normal, then simply pressurize to see if the output changes, or observe whether the sensor zero has output, if there is no change, the sensor has been damaged, it may be the appearance of the damage or the problem of other links of the whole system.
2. The problem of ifm sensor PN2071 pressure sensor sealing ring does not change the output of the pressurized sensor, and the output of the pressurized sensor changes suddenly, and the zero position of the pressure relief sensor cannot be returned, which is likely to be a problem with the sealing ring of the pressure sensor. It is common because of the specification of the sealing ring, after the sensor is tightened, the sealing ring is compressed into the pressure port of the sensor to block the sensor, and the pressure medium cannot enter when pressurized, but when the pressure is high, the sealing ring is suddenly opened, and the pressure sensor is changed by pressure. The way to remove this problem is to remove the sensor and directly observe whether the zero position is normal, and if the zero position is normal, you can replace the sealing ring and try again.
3. The problem of unstable sensor output signal is a problem of stressors. The pressure source itself is an unstable pressure, which is likely to be due to the appearance or the pressure sensor's weak anti-interference ability, the sensor's own vibration is very strong, and the sensor is a problem.
4. It is normal for the sensor and the pointer pressure gauge to have a large error error, and the normal error scale can be recognized. Because of the small measurement scale of the microdifferential pressure sensor, the sensing element in the sensor affects the output of the microdifferential pressure sensor. When the device is installed, the pressure sensor should be axially perpendicular to the direction of gravity, and the zero position of the sensor should be adjusted to the standard value after the device is fixed.
