How to choose a pressure transmitter correctly

The selection of diffusion silicon pressure transmitters, monocrystalline silicon pressure transmitters, and capacitive pressure transmitters is based on the application scenario and specific requirements. The following will provide a detailed introduction to the characteristics, advantages, and application scope of these three pressure transmitters, so that readers can have a comprehensive understanding of these devices and make the correct choice based on actual needs. Diffusion silicon pressure transmitter is a common pressure measurement device, which works by utilizing the stress effect of silicon crystals to measure pressure. This device has the following characteristics: 1. High precision: Diffuse silicon pressure transmitters have high measurement accuracy, reaching 0.1% FS or higher. 2. Good durability: This device uses corrosion-resistant materials and can adapt to various harsh working environments. 3. Wide range: This device can meet the pressure measurement requirements of most industrial fields. 4. Quick response: This device has a fast response speed and is suitable for high demand application scenarios. Due to the following characteristics of diffusion silicon pressure transmitters, they have a wide range of applications in many fields, such as chemical, petroleum, water treatment, etc. Monocrystalline silicon pressure transmitter is a relatively new type of pressure measurement equipment, which has certain advantages in measurement accuracy and stability. Its working principle is to measure pressure through resistance strain gauges on a single crystal silicon wafer. Monocrystalline silicon pressure transmitters have the following characteristics: 1. High precision: This device has a high measurement accuracy, reaching 0.075% FS. 2. High stability: The temperature effect that causes measurement errors in monocrystalline silicon pressure transmitters is small, and it can maintain high measurement accuracy over a wide temperature range. 3. Good shock resistance: The equipment adopts quartz isolation components, which have strong anti vibration ability. 4. High reliability: The single crystal silicon pressure transmitter has a simple structure, reducing the possibility of malfunctions. Due to these advantages of monocrystalline silicon pressure transmitters, they have been widely used in many industries such as aerospace, chemical, metallurgy, and more. Capacitive pressure transmitter is another common pressure measuring device, which measures pressure through changes in capacitance. This device has the following characteristics: 1. High sensitivity: Capacitive pressure transmitters have high sensitivity and can be used to measure small pressure fluctuations. 2. Customizability: The device can be customized according to specific application requirements to meet specific measurement needs. 3. Small size: Capacitive pressure sensors have a small volume, making them easy to install and maintain. 4. High precision: This device has a high measurement accuracy, reaching 0.05% FS. Capacitive pressure transmitters have wide applications in many fields, such as automotive manufacturing, air conditioning systems, medical equipment, etc. In summary, diffusion silicon pressure transmitters, monocrystalline silicon pressure transmitters, and capacitive pressure transmitters all have their own characteristics and advantages, and have different uses in different application scenarios. When making a choice, we should consider the actual needs and requirements for measurement accuracy, stability, and reliability. If higher measurement accuracy and stability are required, a monocrystalline silicon pressure transmitter can be chosen; If a wider range of applications and faster response speed are needed, diffusion silicon pressure transmitters can be chosen; If higher sensitivity and customization are required, capacitive pressure transmitters can be chosen*** The final choice should be determined based on specific application requirements to ensure that the measurement requirements are met and the best measurement results are obtained.
