Sensors will continue to be a “game changer” in many industries, both now and in the future. As the popularity of the Internet of Things (IoT) expands, our demand for sensors is growing. Four different types of sensors are currently the most popular in four industries: manufacturing, healthcare, aviation and agriculture.
1. Pressure sensors
We all know that pressure sensors are capable of sensing the pressure of liquids and gases and then converting it into electrical signal output. With the help of the differential pressure sensor, companies can adopt Internet of Things (IoT) systems to implement real-time monitoring systems. Pressure sensors can also be used to measure fluid/gas flow, velocity, water level and height, etc. For example, in the automotive industry, pressure sensors are used in engines to monitor oil and coolant pressure, as well as in vehicle anti-lock braking systems (ABS), fluid pressure monitoring such as hydraulic pressure, pipeline pressure monitoring, etc. In addition, pressure sensors are also used in aviation, marine, industrial, biomedical instrumentation and other industries.
2. Temperature sensors
As a regular industrial pressure sensor, the temperature sensor is used to measure the temperature or heat energy of a given source by electrical signals.
With the Internet of Things (IoT) systems, temperature sensors can be used in manufacturing, agriculture and health industries. Applications in the manufacturing industry are: plastic extruders, chemical fiber drawing equipment, plastic and rubber manufacturing equipment can simultaneously monitor the pressure and temperature. It is also important to place the machine or equipment in a suitable environment to ensure that the system always maintains a constant temperature. Sensors can solve this problem by providing data that helps track the temperature of a given space.
3. Chemical sensors
As the name suggests, chemical sensors are used to collect information about different parts, such as composition, presence of specific elements or ions, chemical activity, partial pressure, etc.
As an industrial pressure sensor, chemical sensor is used in industrial environments for monitoring and process control to detect hazardous, explosive, or radioactive chemicals, as well as in laboratories and pharmaceutical recycling processes. Various types of chemical sensors include electrochemical gas sensors, chemical field effect transistors, pH glass electrodes, zinc oxide nanorod sensors and chemical resistors.
4. Infrared sensors
Infrared sensor can be defined as electronic devices that are sensitive to certain aspects of the surrounding environment. Infrared sensors can measure the heat of an object and detect motion.
Infrared sensors can be used in healthcare, home appliances, wearable electronics, contactless temperature measurements and other fields. Infrared sensors can also be used for environmental inspections, as it can detect many types of chemicals and heat leaks.
With sensors increasing industrial efficiency and productivity, and the adoption of Industry 4.0 in developing countries, the sensor market is expected to see significant growth in the near future.
