# The selection of pressure transmitter should consider these factors.

##### Author:Source:Date: 2021-05-13 16:41:20
Pressure transmitters have a wide range of applications. It can not only measure the difference between pressure and pressure, but also the difference between liquid level and liquid density. Pressure transmitters are used in many industries. Now there are many types of pressure transmitters, so what factors should be considered when choosing the type of pressure transmitter

First, the range of the transmitter

We need to determine the maximum value of the pressure measured by the pressure transmitter, and then we need to select a pressure range transmitter that is 1.5 times larger than the maximum value. Because, in many systems, there are many peaks and continuous values that fluctuate up and down. Once the value exceeds the peak value of the pressure transmitter, the pressure transmitter will be damaged. Therefore, the maximum value of the pressure transmitter we choose is 1.5 times of the measured medium

Secondly, the medium detected by the transmitter

The reason we use pressure transmitters is to be able to measure the measured medium. If the pressure transmitter we choose is suitable for measuring the medium we choose, then the pressure transmitter is useless. Therefore, we need to select the pressure transmitter according to the measuring medium of the pressure transmitter

Third, the accuracy of the pressure transmitter

The accuracy of the pressure transmitter is mainly determined by factors such as non-linearity, temperature, and zero offset scale. Generally speaking, the higher the accuracy, the higher the price of the pressure transmitter. Therefore, it is best to choose a suitable pressure transmitter according to your needs

Fourth, the temperature range of the pressure transmitter

The temperature of the pressure transmitter has two main aspects, one is the normal working temperature, and the other is the temperature compensation range. When choosing the type of pressure transmitter, it is important not to forget the temperature compensation range.
