Diffused silicon pressure transmitter is a kind of pressure measuring equipment widely used in the field of industrial automation, and its selection is particularly important. Correct selection can not only ensure the accuracy and stability of measurement data, but also improve production efficiency and reduce maintenance costs. This paper introduces the key points of the selection of diffused silicon pressure transmitter from these 5 aspects to help people better understand and apply this technology.
1. The measurement needs are clear
Before the selection, the measurement needs must first be defined. This includes the maximum value, minimum value, range and measurement accuracy of the measured pressure. For different application scenarios, such as liquid, gas or steam, it is necessary to select the corresponding diffused silicon pressure transmitter model. In addition, it is also necessary to consider the physical properties of the measuring medium, such as temperature, corrosion, viscosity, etc., to ensure that the selected transmitter can adapt to the working environment.
2. Accuracy and stability
Accuracy and stability are important indexes to measure the performance of diffused silicon pressure transmitter. Accuracy reflects the degree of deviation between the measured value and the real value of the transmitter, while stability is related to the performance of the transmitter during long-term operation. In the selection, the appropriate accuracy level should be selected according to the actual needs, while paying attention to the long-term stability performance of the transmitter.
3. Output signal and communication protocol
The output signal and communication protocol of the diffused silicon pressure transmitter are also factors to be considered when selecting. Common output signals include analog signals (such as 4-20mA) and digital signals (such as RS485, Modbus, etc.). At the time of selection, the output signal type should be determined according to the needs of the control system. At the same time, it is also necessary to consider the compatibility of the communication protocol to ensure that the transmitter can successfully connect and communicate with the control system.
4. Protection level and environmental adaptability
The working environment of the diffused silicon pressure transmitter may be complex and changeable, so it is necessary to consider its protection level and environmental adaptability. The protection level determines the transmitter's ability to protect against external factors such as dust and moisture. When choosing, the appropriate level of protection should be selected according to the actual situation of the working environment. In addition, it is also necessary to pay attention to the environmental adaptability indicators such as the temperature range and humidity range of the transmitter to ensure that it can work stably in a variety of harsh environments.
5. Brand and after-sales service
In the selection process, brand and after-sales service are also factors that cannot be ignored. Well-known brands generally have high product quality and reliability, and at the same time can provide perfect after-sales service and technical support. When choosing a diffused silicon pressure transmitter, the products of well-known brands can be given priority to ensure the quality and performance of the equipment.
All in all, the selection of diffused silicon pressure transmitters involves many aspects, which need to consider measurement needs, accuracy and stability, output signal and communication protocol, protection level and environmental adaptability, as well as brand and after-sales service. Through scientific and reasonable selection, it can ensure the best performance of diffused silicon pressure transmitter in practical application, and provide strong support for industrial automation production.
