A brief guide to industrial automation sensors


The key to the smart industry is data and information collection. As the Internet and intelligent manufacturing is expanding at a rapid pace, application requirements are increasing simultaneously. Sensors are the critical endings of the smart industry, which are utilised to collect data and give vital data support for the smart industry’s building. It’s a gadget that detects changes in electrical, physical, or other quantities and generates a yield as a confirmation of advancement in the amount. In layman’s terms, Industrial Automation is the process of automating. Sensors are input devices that produce a signal about a specific physical quantity. Smart sensors handle the most basic data upgrade and iterate quickly, resulting in cognitive transformation. It includes everything from industrial process sensing to factory automation and microcontrollers, wired and wireless communications, and cloud servers. 

Industrial automated sensors play a crucial function in making the production clever and computerised in industrial automation. They enable intelligent and automated manufacturing allowing employees to monitor, evaluate, and process various changes that occur on an industrial manufacturing site, such as temperature, motion, pressure, altitude, and external and security changes.

Types of Industrial Automation Sensors

1. Pressure Sensors 

The pressure sensor is a device that apprehends pressure and converts it to an electric signal, the quantity of which is dependent on the applied force. It can sense pressure and transform it into a proper electrical signal using a set of rules. 

A pressure sensor consists of a pressure-sensitive element and a signal processing unit in most cases. Pressure sensors monitor pipelines and send leaks or anomalous alarms to a central computing system, alerting managers to the need for maintenance and repairs.

Applications of pressure sensors: 

  • These high-pressure industrial automation sensors are employed in climate control systems.
  • They are widely used in industrial and hydraulic systems.
  • They are used in various industries such as aerospace, water conservancy and hydropower, production automation, intelligent buildings, railway transportation, petrochemical, oil wells, pipelines etc. 

2. Level Sensors

A liquid level sensor is a device that measures the amount of liquid flowing in an open or closed system. The level of fluids is monitored, maintained, and measured using level sensors. The sensor turns the sensed data into electrical impulses once the liquid level has been determined. 

Applications of level sensors:

  • Many household gadgets such as refrigerator ice makers and washing machines contain level sensors as it is vital to keep the liquid level from rising to the point where it will overflow.

3. Temperature Sensors

Temperature is the most commonly measured physical parameter in industrial production, and many sensors can be employed to monitor it. Temperature and humidity quests are temperature measurement components that gather data and transform data into current or voltage signals that are linearly related to temperature and humidity after circuit processing.

A temperature sensor is a device that receives temperature data from its surroundings and converts it into numerical numbers. 

In industrial automation, digital temperature sensors and temperature and humidity sensors are the most widely utilised.

Applications of temperature sensors: 

  • Temperature sensors are widely utilised in various industries, including medicine, metallurgy, food, printing, dyeing, pharmaceuticals, petrochemicals, and a variety of other applications.
  • They are designed for continuous temperature measurement in air, soil, or water and are waterproof.
  •  For complicated industrial measurements.

4. Proximity Sensors

A proximity sensor is a gadget that can detect how close an object is to it. It recognises the closeness of the thing using the sensitive nature of the displacement sensor and outputs the matching switch signal. Because the proximity sensor can detect without touching the detecting object, it will not wear or harm it, and there will be no spark or noise. It can only detect metal objects at close range and without contact. Because it is a non-contact output mode, it has a long service life and has little impact on the contact’s service life. 

Applications of proximity sensors:

  • Proximity sensors are frequently utilised in aviation, industrial production, and aerospace technology to detect items’ displacement.
  • It is used in resorts, restaurants, garages, automatic doors, automated hot air blowers etc.
