 How to install digital differential pressure transmitter correctly

 
 1. Prepare for work
Verify the correctness of the pressure sensor's code, frequency response, and corresponding frequency response signal.
 
2. Size to match
The size refers to the size of the mounting hole and is matched to the size of the sensor because the threaded portion is susceptible to wear during installation. This not only affects the sealing performance of the equipment, but also makes the pressure sensor not fully function, and may even pose a safety hazard. Mounting holes can be tested with a mounting hole gauge to avoid discrepancies.
 
3. Keep the mounting holes clean
Do you know what is the first step in taking a big movie with your mobile phone? Wipe the camera clean! Don't think it's a slippery one. In fact, many people don't realize the importance of this. Just like when installing a sensor, keeping the mounting holes clean and preventing clogging of the melt is important to ensure proper operation of the equipment.
 
4. Choose the right location
The pressure sensor must be installed along the cable, preferably at the cable connector, and each cable is equipped with no less than four pressure sensors. At the same time, in order to facilitate the determination of the pressure sensor failure point, in addition to the installation of the pressure sensor at the starting point, an additional 150~200m from the starting point should be installed.
 
5. The environment is very important
It should be installed in a ventilated, dry, non-corrosive, cool place. If it is installed in the open air, a protective cover should be added to avoid the normal use of the product due to sunlight and rain. If the sensor has to be exposed to water or moisture, choose a special sensor that is extremely water resistant.
 
6. Prevent pressure overload
Even if the overload design of the pressure sensor's pressure range can reach 50% (out of the maximum range ratio), it should be avoided as far as possible from the safety point of operation of the equipment. It is best to select the sensor whose measured pressure is within the range. In general, the optimal range of the selected sensor should be twice the measured pressure, so that the pressure sensor can be prevented from being damaged even under extremely high pressure.
