A pressure transmitter is a pressure sensor that outputs a standard signal; it is a device that receives a pressure variable and converts it proportionally into a standard output signal. It can convert the physical pressure parameters of gases, liquids, etc., detected by the pressure-sensing element, into standard electrical signals (such as 4–20 mADC), which are then supplied to secondary instruments such as indicator alarms, recorders, and regulators for measurement, indication, and process control. It is widely used in industries such as petroleum, electricity, chemicals, and transportation. The media it can measure include liquids, vapors, gases, etc. As its applications expand, damage is occurring more and more frequently. In summary, what are the exact reasons that cause damage to pressure transmitters? 1. During the use of pressure transmitters, the diaphragm is subjected to forces from hard objects, which can lead to damage to the isolation diaphragm. II. Influence of the measuring medium. When pressure transmitters are used to measure substances with high temperatures such as steam, failure to implement appropriate cooling measures can cause damage to the diaphragm inside the transmitter. III. In addition to specifying requirements for heat dissipation measures, corresponding requirements must also be set for the temperature of the medium under test. In short, the temperature of the medium being measured must not exceed the maximum temperature that the pressure transmitter can handle; otherwise, it is necessary to use it in conjunction with a cooling device. IV. It is important to note that if the temperature of the medium being measured is too high, it can cause damage to the transmitter. On the other hand, if the temperature is too low, especially when freezing occurs, this can also damage the diaphragm of the pressure transmitter, leading to damage to the transmitter as well. It is very necessary to take proper insulation measures for pressure transmitters used in winter or outdoors. V. Requirements regarding voltage level. In many cases, pressure transmitters get damaged due to excessive voltage. To prevent such phenomena from occurring, the voltage applied to the pressure transmitter should not exceed 36 V. These are the main reasons that lead to the damage of pressure transmitters. I hope this will be helpful to everyone in using pressure transmitters in industrial production. Additionally, great care must also be taken when transporting pressure transmitters. For more information, please visit the company’s official website at http://www.yb1518.com/.
