Pressure transmitter temperature range
The pressure transmitter usually calibrates several temperature sections, one is the working environment temperature, one is the medium temperature, one is the storage temperature, and the other is the compensation temperature. Operating ambient temperature refers to the temperature range that will not be destroyed when the pressure transmitter is in operation. The compensation temperature refers to the temperature range where the pressure transmitter can meet the application performance index. When the compensation temperature range is exceeded, the pressure transmitter may not reach the original performance index. The temperature compensation range is a typical range that is smaller than the operating temperature range. In this range, the working transmitter will surely reach its proper performance.
Changes in temperature affect its output in two ways. One is zero drift, and the other is full-scale output. For example: ±X %/°C of full scale, ±X%/°C of reading, ±X% of full scale when out of temperature range, ±X% of reading when within temperature compensation range, without these parameters will result in Uncertainty in use. Whether the change in the output of the transmitter is caused by a pressure change or a change in temperature. Temperature effects are the most complicated part of understanding how to use the transmitter. If you need to amplify the output signal, it is best to use a transmitter with built-in amplification. It is better to use mA output or frequency output for long-distance transmission or strong electronic interference signals. If you want to select mA or frequency output in an environment with high RFI or EMI specifications, consider special protection or filters.
