RS Pro Wirewound Pt100 PRT Sensing Elements. RS Pro offers high-quality and reliable Pt100 PRT (Platinum Resistance Thermometer) or RTD (Resistance Temperature Detector) wirewound platinum sensing elements. This wirewound element's cylindrical shape makes it ideal for housing within a protective metal tube or jacket. This wirewound Pt100 sensor is designed for optimal performance and stability, providing accurate and reliable temperature measurement in a variety of applications. What is an RTD? An RTD is a type of temperature sensor based on the correlation between metal and temperature. As the temperature of a metal increases, it resists electrical current more. This resistance can be measured and converted into a temperature reading. The "Pt" in "Pt100 RTD" stands for platinum (platinum wire or film), and the "100" indicates that the temperature sensor has a resistance of 100 Ω at 0°C. Platinum is the most reliable metal because its resistance changes linearly over a wide temperature range. What is a wirewound sensor element? This wirewound PRT sensor element consists of pure platinum wire wound in a tightly spaced spiral. The wire spiral is located inside the axial bore of a high-purity alumina ceramic rod. The design of the Pt100 sensor element allows the platinum wire to move freely when expanding and contract as it heats. This improves stability and accuracy at the final temperature and eliminates resistance anomalies caused by clamped wire. The only drawback of this Pt100 element is its susceptibility to shock and vibration. Features and Benefits: Long-term stability, high accuracy, wide temperature measurement range -200 to +650°C, two lead wires, cylindrical design ideal for insertion into housings or sheathing. Applications: These wirewound temperature sensor elements are suitable for use in a variety of applications and industries. Automotive, Chemical, Microelectronics, Air Conditioning and Refrigeration, Air, Gas, and Liquid Temperature Measurement, Food Processing, Laboratory. Frequently Asked Questions: How do PRT temperature sensors work? PRT temperature sensors operate by placing the sensor element (or process end) in the equipment or process requiring temperature measurement. The higher the temperature rises in a platinum resistor thermometer, the greater its resistance to electrical current. For every degree increase in temperature, the electrical resistance also changes by a set ratio. This ratio is called the temperature coefficient. For platinum, this ratio is 0.00385 Ω/Ω/°C. For a Pt100 with a resistance of 100 Ω, the increase in resistance per degree Celsius is 0.385 Ω. This allows the total resistance measurement to be measured and converted to temperature. How to measure resistance. The resistance developed by the temperature sensor is measured by passing a current through one of the wires, generating a voltage. This voltage is measured using a suitable bridge or voltmeter, and the resistance is calculated using Ohm's law (R=V/I). Once the resistance is known, it can be converted to a temperature measurement using a calibration equation or Pt100 table. A temperature measurement device or calibrator can also be connected to the probe leads to automatically convert the measured resistance to a temperature measurement.
