Main classification and selection principles of sensors 2

2、 Classified by measured physical quantities:

1. Displacement sensor: used to measure the displacement of objects, including linear displacement sensors and angular displacement sensors.diode

2. Pressure sensor: used to measure the pressure changes of the medium.

3. Temperature sensor: used to measure temperature changes in the environment or objects.

4. Gas sensors: used to detect gas components in the air, such as oxygen sensors, methane sensors, etc.

5. Liquid sensor: used to detect parameters such as liquid level and flow rate.diode

The selection principles for sensors include but are not limited to:

1. Measurement requirements: Select appropriate measurement range, accuracy, and other parameters based on specific application requirements.diode

2. Environmental factors: Consider factors such as temperature, humidity, and vibration in the working environment of the sensor.

3. Durability and stability: Choose sensors with good durability and long-term stability.diode

4. Cost effectiveness: Choose sensors with reasonable costs while meeting performance requirements.

5. Compatibility: Ensure that the selected sensors are compatible with the system hardware and software.

6. Brand and after-sales service: Choose products from well-known brands with good after-sales service to ensure the reliability and ease of maintenance of the equipment.diode

In short, the classification and selection principles of sensors are comprehensively considered based on specific application scenarios and measurement requirements, ensuring the selection of the most suitable sensor to improve system performance and stability.diode
