Temperature Sensor Types and Information

Oven Industries offers a multitude of temperature sensor types to work in conjunction with our temperature controllers for expeditious and precise reading. The three main types of temperature sensors are RTD, Thermocouple, and Thermistor. Most Oven Industries temperature sensors are interchangeable within the specific temperature range for which they are designed – meaning in the event one is damaged, it can be swapped out with no need to recalibrate the thermal system. Custom designed temperature sensors and probes are also available.

RTD:
Resistance Temperature Detectors, or RTD’s for short, use resistance temperature characteristics to change value depending on the ambient temperature. RTD’s are widely used because of their accuracy and stability with temperature controllers. Wire RTD’s are usually made of platinum wound in a coil and connected to a pair of leads. Platinum is used because it accurately supports the widest range of temperatures while keeping a very tight tolerance. This allows RTD’s to be monitored from longer distances than other types of probes with a higher accuracy. The nature of the wire RTD makes it a positive temperature coefficient, which means that as heat is applied the resistance value will increase. Many temperature controllers Oven Industries offers can be used in conjunction with any typical RTD, and custom designed solutions can be built using any RTD specification.

Thermistor:
Similar to the RTD is the thermistor. A thermistor is a temperature sensing device made of a semiconductor material that exhibits a large change in resistance for a small change in temperature. Thermistors usually have negative temperature coefficients, although they are also available with positive temperature coefficients. The main benefit of a thermistor over an RTD is that it has a larger range of motion, allowing it to cover a wider range of temperature. Oven Industries produces a wide array of thermistors as well as custom built probes to meet just about any requirement for controlling temperature.

Thermocouple:
A thermocouple is a temperature sensing device made by joining two dissimilar metals. This junction produces an electrical voltage in proportion to the difference in temperature between the hot junction (sensing junction) and the lead wire connection to the instrument (cold junction). As the sensing junction and the cold junction are exposed to different temperatures, a millivolt potential is formed. This potential can then be calculated as a temperature based on the type of thermocouple used, the materials of the junctions, and the magnitude of the potential.

AC applications:
For just about any heating requirement, Oven Industries AC temperature controllers offer high watt output and excellent power output capability with a small overall footprint. As one of the only products to offer an output stage embedded into the module, there is no need to purchase an external output stage to drive your devices. The use of a triac drive technology allows our AC temperature controllers to perform zero voltage crossing with incredible accuracy. Custom designed chassis allow for easy implementation into any industrial or commercial temperature application.

DC applications:
Plug and go with Oven Industries DC temperature controllers; built-in power supplies convert AC into DC for the flexibility to power just about any device. Precision thermoelectric temperature control is the reason so many companies choose Oven Industries to manage their thermal needs related to medical devices, lab diagnostics, aerospace, and defense. Many of our temperature controllers have a solid state H-bridge design, which allows power to be delivered to a load with minimal loss and seamlessly transition from heating to cooling. Highly accurate heating and cooling can be achieved with minimal setup, making it simple to integrate into any design.
