High Temperature Inductive Proximity Sensor [Specifications, Applications,...]

Sensors, specially inductive sensors are used in most devices, which can be used to help improve work and speed it up a lot. Inductive sensor which is a subset of proximity sensors are used to detect metal objects without any contact. 

The inductive sensor works based on a magnetic circuit. Inductive sensors are only used to detect metals due to their structure, but they do so with the utmost confidence. 

These types of sensors are very resistant to environmental factors and are commonly used in harsh environments because they are generally strong and can provide stable signals even in hostile environments. 

Industrial processes often generate heat, and Detection of metal parts is not always done at low temperatures, so we have to use inductive sensors in high-temperature environments. 

As a result, the standards inductive sensors that are rated up to 70 ºC are not resistant enough and usable for many industrial applications and its electronic components will be damaged in this condition and provide non-reliable results. 

Why Use High Temperature Proximity Sensor

If standard inductive sensors are used in high temperatures, the change in the defined sensing distance will be larger.

In this situation, the sensing distance starts to increase, and also operating and reset points increase and a difference between these two points arises. so the sensor does not reset and if the rising in temperature continues and the operating point increases when there even is no object the sensor continues its working. 

In this case, special temperature inductive sensors should be used so extended temperature models are developed.

These sensors are able to operate even at temperatures up to 250 °C with high reliability. 

Exceptional working conditions require reliable and flexible performance, and high-temperature inductive sensors do the job well in all respects. 

High-temperature sensors are designed for continuous operation in high-temperature environments and are ideal for the toughest environments. 

Specification of High Temperature Inductive Proximity Sensor

Stainless steel housing, resistant electronics, and a cable jacket made from silicone used in their construction. 


These sensors are proper for use in:

  • Chemical and wash-down applications
  • Steel production
  • Glass manufacturing
  • Vehicle spray painting ovens
  • Plastic injection molding machines
  • Forging
  • Foundry processes
  • Metalworking

and other extreme environment applications for monitoring and detection tasks in the high-temperature areas where the deployment of personnel is impossible. 

Since inductive sensors operate based on the generating magnetic fields, the high temperature and operating environment of the sensor does not affect magnetic fields.

Key benefits of the high-temperature inductive sensor

  • Continuous operation up to 250 ° C
  • Stainless steel structure to use in harsh environments
  • Excellent temperature stability
  • High strength and excellent performance under high-temperature
  • High precision
  • Reliable in harsh environments
  • by using these kinds of sensors process quality increased
  • A high degree of protection up to IP68

When designing mechanical systems It is important to choose high-quality sensors that will not break down or create hazardous conditions in the application setting. 

High temperature proximity sensor from Dubai Sensor can withstand ultra-high temperatures up to 250 °C and are ideal for use in extreme ambient and product temperature conditions to detect metallic objects in various temperature ranges.

As you saw, this article was about high temp inductive sensors. inductive sensors are a kind of proximity sensors. To know about other kinds of these sensors briefly, please check out our article on types of proximity sensors.
