How to choose diffused silicon pressure transmitter, monocrystalline silicon pressure transmitter, capacitive pressure transmitter

The selection of diffused silicon pressure transmitters, monocrystalline silicon pressure transmitters and capacitive pressure transmitters is based on the application scenario and specific requirements. The characteristics, advantages and application ranges of these three pressure transmitters will be introduced in detail below so that readers can fully understand these devices and make the right choice based on actual needs.

Diffused silicon pressure transmitter is a common pressure measurement device. Its working principle is to use the stress effect of silicon crystal to measure pressure. This device has the following features:

1. High accuracy: The diffused silicon pressure transmitter has high measurement accuracy, which can reach 0.1%FS or higher.

2. Good durability: This equipment uses corrosion-resistant materials and can adapt to various harsh working environments.

3. Wide range: This equipment can adapt to the pressure measurement requirements of most industrial fields.

4. Fast response: The device responds very quickly and is suitable for demanding application scenarios.

Due to the following characteristics of diffused silicon pressure transmitter, it has wide applications in many fields, such as chemical industry, petroleum, water treatment, etc.

Monocrystalline silicon pressure transmitter is a newer type of pressure measurement equipment and has certain advantages in measurement accuracy and stability. Its working principle is to measure pressure through a resistance strain gauge on a silicon crystal single chip. Monocrystalline silicon pressure transmitter has the following characteristics:

1. High accuracy: This equipment has high measurement accuracy, which can reach 0.075%FS.

2. High stability: The temperature effect that causes measurement errors is small and the single crystal silicon pressure transmitter can maintain high measurement accuracy in a wide temperature range.

3. Good shock resistance: This equipment uses quartz isolators, which has strong vibration resistance.

4. High reliability: The simple structure of the monocrystalline silicon pressure transmitter reduces the possibility of failure.

Due to these unique advantages of single crystal silicon pressure transmitter, it has been widely used in many industries, such as aerospace, chemical industry, metallurgy and other fields.

Capacitive pressure transmitter is another common pressure measurement device. Its measurement principle is to measure pressure through changes in capacitance. This device has the following features:

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 needs to meet specific measurement requirements.

3. Small size: Capacitive pressure sensors are small in size and easy to install and maintain.

4. High accuracy: This equipment has high measurement accuracy, which can reach 0.05%FS.

Capacitive pressure transmitters are widely used in many fields, such as automobile manufacturing, air conditioning systems, medical equipment, etc.

To sum up, diffused silicon pressure transmitters, monocrystalline silicon pressure transmitters and capacitive pressure transmitters have their own unique characteristics and advantages, and have different uses in different application scenarios. When choosing, we should consider based on actual needs and requirements for measurement accuracy, stability and reliability. If you need higher measurement accuracy and stability, you can choose a single crystal silicon pressure transmitter; if you need a wider application range and faster response speed, you can choose a diffused silicon pressure transmitter; if you need higher sensitivity And customizability, capacitive pressure transmitters can be selected. The final selection should be determined based on specific application needs to ensure that measurement requirements are met and optimal measurement results are obtained.
