What is an RTD?. An RTD is a type of temperature sensor based on the correlation between metals and temperature. As the temperature of a metal increases so does its resistance to the flow of electricity. This resistance can be measured and converted to a temperature reading. In a Pt100 RTD ??Pt ??stands for platinum (platinum wire or film) and ??00 ??means that the temperature sensor has a resistance of 100 Ohms at 0°C. Platinum is the most reliable metal due to its linear resistance to temperature relationship over a large temperature range. What is a Pt100 Probe?. A Pt100 probe is the most rugged form of RTD. The Pt100 temperature sensor element is mounted inside a metal sheath or probe. This protects it from being damaged by the surrounding environment when it is inserted into the process to be measured. The other end of the probe is terminated by an insulated lead comprising of 4 wire tails which are connected to the temperature measuring equipment. Features and Benefits.

Applications. These Pt100 PRT sensor probes with their robust design are ideal for use in many general purpose industrial applications including the following:. Air conditioning and refrigeration Chemical industry Plastics processing Stoves and grills Air, gas and liquid temperature measurement Exhaust gas temperature measurement Food processing Laboratories. Frequently Asked Questions. How Does a PRT Temperature Sensor Work?. The PRT temperature sensor works by placing the sensor element (or process end) into the equipment or process that requires temperature measurement. As the temperature of the platinum resistance thermometer increases it ??s resistance to the flow of electricity increases. For every increase per degree of temperature the electrical resistance also changes by a set ratio, this is called the temperature coefficient. For platinum, this ratio is .00385 ohm/ohm/°C which means for a Pt100 with a 100 ohm resistance the increase in resistance per degree of temperature would be 0.385 ohms. The total resistance reading can, therefore, be measured and converted into temperature. How is the Resistance Measured?. The resistance generated by the temperature sensor is measured by passing current through one of the wires to produce a voltage. This voltage is then measured using a suitable bridge or voltmeter and the resistance calculated in ohms using Ohm ??s Law (R=V/I). Once the resistance is known you can convert it to a temperature reading using a calibration equation or a Pt100 table. A temperature measurement device or calibrator can also be connected to the leads of the probe that will automatically convert the measured resistance into a temperature reading.
