Pressure sensor routine maintenance methods

Pressure sensors have been Piezo Buzzer widely used in many environments need to be applied both to the pressure sensor, maybe we know how to choose the pressure sensor, but also know how to use a pressure sensor, but do you know how to maintain the pressure sensor it? Routine maintenance pressure sensors are those methods? Pressure sensor manufacturers generally one year warranty, and some two-year warranty, but manufacturers will often go without which you maintain the pressure sensor, so we still need to know about the pressure sensor routine maintenance methods. There are about 8 o'clock: one, to prevent the waste deposited in the conduit and sensors with corrosive or hot media contacts. 2, the measurement of gas pressure, the pressure port should be open in the flow line to the top, and the sensor should be installed in the upper part of the process piping so that the accumulation of fluid injected into the process pipeline easily. 3, measuring fluid pressure, the pressure port should be opened in the side of the pipeline process, in order to avoid deposition Magnetic Transducer of slag accumulation. 4, guide pressure pipe should be installed in place of small fluctuations in temperature. 5, measuring liquid pressure, the sensor should be installed to avoid the impact of the liquid (water hammer phenomenon), in order to avoid overvoltage damage the sensor. 6, winter freezing occurs when the sensor is installed outdoors freezing measures must be taken to avoid the impulse in the mouth due to icing fluid volume expansion, resulting in loss of the sensor. 7, the wiring, the cable through the waterproof connector or entangling pipe and tighten the nut tight seal to prevent leakage of rainwater through the cable into the transmitter housing. 8, the measurement of steam or other high temperature medium, the need to take additional buffer tube (coils) and other condenser operating temperature of the sensor should not Loudspeaker exceed the limit. Understand the above points pressure sensor routine maintenance method is very helpful to us, so as to ensure that our pressure sensor with longer and more stable performance. Of course, this is just routine maintenance points, there pvc film are other needs attention, such as after a year can be sent back to the factory for calibration, offset, appears to prevent the sensor.
