The primary function of a sensor is to detect and measure physical quantities or phenomena in the environment and convert them into usable electrical signals or other means of output signals. The functions of sensors can be summarized in the following aspects:
1. Detection: The sensor can sense various physical quantities in the environment, such as temperature, humidity, pressure, light intensity, sound, etc. They are able to monitor and detect changes in these parameters in real time.
2. Measurement: The sensor can accurately measure the physical quantity to obtain accurate numerical data. For example, a temperature sensor can measure the actual temperature of the environment, and a pressure sensor can measure the pressure of a liquid or gas.
3. Monitoring: Sensors can be used to monitor and control the operation status of various equipment or systems. For example, accelerometers can be used to monitor the oscillations of machinery, and light sensors can be used to adjust the brightness of indoor lighting systems.
4. Detect anomalies: Sensors can be used to detect anomalies or faults in the environment. For example, a flame sensor can detect a fire, and a smoke sensor can detect smoke so that the appropriate measures can be adopted in a timely manner.
5. Automatic control: Sensors are an important part of complete automatic control. Through the connection with other devices or systems, the sensor can sense changes in the environment in real time and trigger corresponding control operations according to preset conditions to complete the automation function.
In summary, the main function of ifm sensors is to sense and measure physical quantities in the environment and convert them into usable signals for various use requirements, such as detection, measurement, monitoring and automation.

How to care for ifm sensors
1. When measuring the liquid pressure, in order to prevent the sensor from being damaged by overpressure, the device position of the sensor should prevent the impact of the liquid.
2. When measuring steam or other high-temperature media, it is necessary to connect a condenser such as a buffer pipe.
3. The impulse pipe should be installed in a place where the temperature fluctuation is small.
