A Pressure transmitter is a kind of equipment used to measure, convert, and transmit pressure signals, which is widely used in industrial automation control systems. When choosing a 2088 pressure transmitter, we need to consider several factors, including the range, accuracy requirements, working environment, measuring media, etc. This article will provide you with a pressure transmitter selection guide to help you choose the right pressure transmitter.

The rangeability of a pressure transmitter 4-20mA refers to the range of pressure can be measured. When selecting a pressure transmitter, you need to determine the required pressure range. Taking into account the pressure changes in practical applications, it is generally recommended to choose a industrial pressure transmitter with a range slightly larger than the actual demand. If the pressure range is too small, pressure range may not meet the exact demand; If the pressure range is too large, resources may be wasted.

For small pressure measurements, such as the diaphragm pressure gauge is suitable for the pressure range from -60kpa to +60kpa, and the pressure vacuum gauge is suitable for the pressure range from -0.1MPa to +2.4MPa. In this case, will generally choose a diaphragm pressure gauge or pressure vacuum gauge.

For the measurement of general liquid and gas pressure, such as water, oil, and air pressure, ‌the commonly used range is 0~1MPa. ‌and for higher pressure liquid and gas measurement, such as steam, compressed air, and liquefied gas, the ‌range is 0~10MPa.

In a larger pressure range,‌ such as petroleum,‌ chemical industry,‌ aerospace, and other fields of pressure measurement,‌ the range can reach 0~25 MPa.‌ For higher intensity pressure measurements,‌ such as pressure vessels,‌ deep sea exploration, nuclear power plants, and other fields, the range is 0~100 MPa.

In addition, ‌there are other pressure gauges with smaller or larger ranges, ‌such as 0~ 0.6MPa, and ‌0~ 250MPa, ‌for special occasions and special pressure measurement needs.

The ranges of the ATMH(Micro-Heart) Differential/Gauge/Absolute Pressure Transmitters(https://youtu.be/Mjo9f5fgh8w?si=g8SpPPGWUqBpoE6v) we produce can be measured as follows:

1A  0-124Pa~6kPa

1A  0-1kPa~62kPa

1A  0-5kPa~248kPa

1A  0-41kPa~2068kPa

1A  0-276kPa~1389kPa

1A  0-550kPa~27500kPa

The typical basic error of the digital differential pressure transmitter(https://youtu.be/DgXVSMTo1QY) is ±0.075%. Therefore, choosing the right range of pressure transmitters HART is very important to choose the right range of pressure transmitters, which ‌can’t only improve the measurement accuracy, but can also extend the service life of the instrument.
