Both the RTD itself and its accuracy must be considered when selecting the RTD sensor. The temperature range varies with element type, and the accuracy denoted at calibration temperature (usually at 0°C) varies with temperature. Thus, it is important to define the temperature range...
This change in the temperature of the element being directly proportional to the heat, provides a direct reading of the applied temperature levels. In this article I have explained how rtds work and also how to make a simple high temperature sensor circuit using a homemade RTD device. A direc...
A Resistance Temperature Detector (RTD) is a passive temperature sensing device based on the principle that the resistance of a metal varies with temperature. The electrical current passing through the sensor’s element or resistor generates a resistance value. This value is then measured by an att...
In this article, we will focus on RTDs. However, there are many different types of temperature sensors—RTDs, thermistors, and thermocouples. The sensor to use in a design depends on the accuracy required and the temperature range being measured. Each sensor type has its own requirements: Biasi...
