2021925 · Noncontact Temperature Sensors. Virtually any mass above absolute zero temperature emits electromagnetic radiation (photons, or light) as a function of that temperature. This basic fact makes possible the measurement of temperature by analyzing the light emitted by an object. The StefanBoltzmann Law of radiated energy quantifies this fact ...


Non contact Temperature Sensor Types These types of ...

These sensors are noncontacting sensors. For example, if you hold an IR sensor in front of your desk without establishing any contact, the sensor detects the temperature of the desk based on the merit of its radiation. These sensors are classified into two types such as thermal infrared sensors and quantum infrared sensors.

202141 · Noncontact thermometers enable an individual’s temperature to be taken with either limited (tympanic) or no contact (noncontact infrared thermometer, thermal scanner). This means that temperature can be determined without the pain of having to keep the mouth, armpit, or rectum immobilized with a thermometer long enough to get an accurate ...


Types of Contact Sensors Thomasnet

20211111 · Contact sensors have the ability to measure their own temperature—if there is no heat transfer between the sensor and the item it is attached to, the sensor can correctly gauge the temperature. However, it is possible for errors to occur, especially when measuring surface temperature or attempting to take the temperature of a moving surface.
