Analysis of the main basis for the selection of intelligent pressure transmitter

- Jul 29, 2020-

The choice of intelligent pressure transmitter UIB6 is mainly based on the measurement medium, temperature environment, accuracy, installation and maintenance, etc. After determining the manufacturer and model of the transmitter, determine the range of the transmitter according to the requirements of use. When select the range, the principles of adjustable range, high precision, and appropriate price should be followed.

1. Liquid contact material

Generally, the material of the pressure transmitter that contacts the medium is 316 stainless steel. If the measuring medium is not corrosive to 316 stainless steel, then basically all pressure transmitters are suitable for measuring the pressure of the medium; if the measuring medium is corrosive to 316 stainless steel, a corrosion-resistant material is required.

2. Accuracy

Each instrument has accuracy errors, but due to the different accuracy levels of each country, for example, the accuracy of China and the United States is the good part of the linear SUI of the sensor, that is, between 10% and 90% of the measurement range, while the European standard accuracy is the bad part of the linear SUI.

3. Output signal

Due to various collection needs, there are many kinds of output signals of smart pressure transmitters UIB6-D on the market, mainly 4~20mA, 0~20mA, 0~10V, 0~5V, etc. The more commonly used ones are 4-20mA and 0-10V. Only the 4-20mA signal is a two-wire system (excluding grounding and shielding wires), and the rest are three-wire systems.
