Regarding the selection of pressure gauges
Thread Content
Just saw a post whose content was: “When choosing a gauge, the following aspects are usually taken into consideration: what materials are used for contact with the medium, what is the resolution of the signals, what is the refresh rate of the signals, what is the accuracy of the signals, and what is the range along with the protection rating.” Questions: What do “resolution of the signals,” “refresh rate of the signals,” “accuracy of the signals,” and “protection rating” refer to respectively?
Thank you! I still don’t quite understand the relationship between these data and the selection of pressure gauges.
Do you have QQ? I want to add you. I’m seeking your advice. I’m a newcomer to this field; I work as a salesperson in an instrument factory, and I feel that learning how to select instruments is essential.
“What is the resolution of the signal?” and “What is the refresh rate of the signal?”: These two parameters are hardly ever used in typical selection processes. “What is the accuracy of the signal?” refers to the percentage of the full measurement range occupied by measurement errors; values such as 0.075%, 0.1%, 0.2%, 0.55%, etc., represent this accuracy. The “protection rating” refers to the device’s ability to resist dust and water; for most outdoor instruments, an IP67 rating is sufficient. For more detailed information, it is necessary to check the specific corresponding rating
