What are temperature sensors?

Temperature sensors are special types of electronic devices that are primarily used to detect and measure any temperature change of any solid objects or surfaces, as well as of air or liquid. The most basic examples of temperature sensors are thermometers. 

Types of temperature sensors

There are different types of temperature sensors available in the market. These include: 

Thermistors

Thermistors refer to the very small-sized temperature sensors that are designed to measure temperature by detecting any change in the resistance of the electric current. 

Resistance Temperature Detectors (RTDs)

These types of temperature sensors operate just like Thermistors but measure temperature based on ohmic resistance. 

Thermostats

Thermostats are temperature sensor devices designed to detect the temperature of a physical environment and regulate the temperature as per needs. 

Temperature Probes

Temperature probes are one of the most widely used and versatile temperature sensors. They usually possess a thermistor, an RTD, or a thermocouple along with a terminal head. 

Applications of temperature sensors

Temperature sensors have a diverse range of applications. Most commonly, they are used in:

• Industrial workspaces: Specifically in monitoring machinery, manufacturing equipment, and power plants. 
• Hospitals: In different medical equipment & devices like patient monitors, ventilator flow tubes, and humidifiers, for example.
• Laboratories: For science and biotech monitoring. 
• Domestic consumer-based appliances: In ovens, refrigerators, electric kettles, etc. 
• HVAC applications: Across heating systems and air conditioning systems.
• Automotive industries: In engine temperature measurement.
