Resistance Temperature Detector­(RTD)­2 Wire,3 Wire,4 Wire Systems Power Supply for RTD An electric dc power supply is required to provide current for the resistance measuring circuit. Read More > How to choose the right sensor technology RTD or Thermocouple? In both cases, the sensor is wired to a transducer or signal conditioner that has been calibrated to accept the input voltage or resistance, calculate the correct temperature, and output it as a 4-20 mA, mV, or digital signal to an automation system. This electrical wire acts as a temperature sensor. Resistance Temperature Detector (RTD) is also called as a resistance thermometer. It does not produce an output on its own. An RTD is a passive device. In essence, any metal could be used for RTD, but the choice is limited due to considerations such as cost, temperature coefficient of the resistance, ability to resist oxidation, manufacturing constraints, and stability [44] . RTD Resistance versus Temperature RTD temperature measurement involves the following two steps which are described in the consecutive sections: 1. See How to Convert RTD Resistance to Temperature. Most RTD elements consist of a length of fine coiled wire wrapped around a ceramic or glass core. Resistance Temperature Detector is a general term for any device that senses temperature by measuring the change in resistance of a material. The combination of resistance tolerance and temperature coefficient define the resistance vs. temperature characteristics for the RTD sensor. Next we take a look at how to convert resistance to temperature: Problem 1: What is the resistance of a platinum resistor at 250°C, if its resistance at 20°C is 1000 Ω? Resistance Temperature Detectors (RTDs) are temperature sensors that contain a resistor that changes resistance value as its temperature changes. Notice that the tables for the various platinum curves are for the standard 100 ohm @ 0°C sensor. An electric dc power supply is required to provide current for the resistance­ measuring circuit. The temperature-resistance relationship for the PT1000 is stored in the software so the temperature is calculated automatically. Subscribe to Our Blog; Latest Blogs. The resistance vs temperature relationship is well known and is repeatable over time. Measure the RTD resistance accurately 2. RTD sensor is basically a temperature sensing device in which change in resistance of the detector element is calibrated with temperature.

While a thermistor with a 1% accuracy is considered precise and acceptable, an RTD with a … It required an external current source to work properly. The larger the element tolerance, the more the sensor will deviate from a generalized curve, and the more variation there will be from sensor to sensor (interchangeability). Above 0 °C, RTD temperature is specified by the RTD resistance at 0 °C (R0) and constants A and B. The element is usually quite fragile, so it is often placed inside a sheathed probe to protect it. Tables capture the nuances of an RTD’s non-linearity without adding any mathematical complexity: simply look up the resistance corresponding to a given temperature, or vice-versa.
