In most applications, temperature is a parameter that needs to be constantly monitored. This is because the functioning of an application depends on the temperature. Hence, monitoring is important to make sure the optimal temperature is maintained at all times. For this particular function, we use temperature sensors like Resistance Temperature Detector (RTD) sensors, thermocouples, etc.
What is a Resistance Temperature Detector (RTD) Sensor? How Does It Work?
An RTD Sensor is a device that tracks the temperature of an application by measuring the change in resistance of the sensor in relation to temperature. As temperature changes the resistance of the RTD sensor changes as well. This change in resistance is predictable, depending on the resistance curve of a certain RTD, and can be measured in order to calculate the temperature that the RTD sensor is seeing. (more…)
