Non-contact Temperature Sensors - Inst Tools

Sensing the thermal radiation emanated from a pipe, for instance, only tells you the surface temperature of that pipe and not the true temperature of the fluid within the pipe. Another example is when doctors use non-contact thermometry to assess irregularities in body temperature: what they detect is just skin temperature.

Types of Contact Sensors - Thomasnet

Jul 08, 2021· Thermocouples. This type of contact sensor is extremely useful and versatile. They are affordable, easy to replace, and have standardized connectors. They measure the temperature between two points, not the absolute temperature. A cold junction is often incorporated into the thermocouple, to provide a set known temperature as a frame of reference.

Non-contact Temperature Sensors - Inst Tools

Non-contact 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 Stefan-Boltzmann Law of radiated energy quantifies this fact ...

What is a Temperature Transducer? - Definition & Types ...

Non-contact Type Temperature Sensor Device. The sensing element is directly not contacting the thermal source. They use convection phenomenon for the transfer of heat. The convection is the process in which the heat is transfer by the movement of the substance. The non-contact type transducer is sub-categorised into the following categories.

Contact And Non-Contact Varieties Of Temperature Sensors

Thermal equilibrium simply means that the two bodies have no heat flowing between them and are hence the same temperature. There are however a variety of errors that can occur when using these types of sensors, for instance surfaces are especially hard to measure with contact sensors, in such instances a non-contact method is more avoidable.
