FAQs

What is an RTD Sensor?

An RTD sensor, or Resistance Temperature Detector, is a device used to measure temperature. An RTD probe works by sensing the change in the electrical resistance of a metal wire as the temperature changes.

This change in resistance is then converted into a temperature reading, providing high accuracy temperature measurements in various applications and industries.

What is a Platinum Resistance Thermometer?

A Platinum Resistance Thermometer (PRT) is a type of temperature sensor that utilises the change in electrical resistance of platinum wire to measure temperature.

PRTs are known for their high accuracy, stability, and wide temperature range, making them ideal for various industrial, scientific, and metrology applications.

What is a Platinum Resistance Thermometer Used For?

Platinum resistance thermometers (PRTs) are used for precise temperature measurement in industrial applications, offering greater stability and accuracy than thermocouples or thermistors. They excel in environments requiring fast response time and vibration resistance. PRTs are crucial in calibration processes, HVAC systems, and scientific research, providing reliable readings from very low to high temperatures.

How Accurate is a Platinum Resistance Thermometer?

Platinum resistance thermometers offer exceptional accuracy, typically within ±0.1°C or better. Their high resistance and stable resistivity ensure precise measurements.

Calibrated in accordance with IEC standards, PRTs maintain accuracy across a wide temperature range. Professional knowledge and use of Fluke calibrators can further enhance their precision, minimising thermoelectric voltages and contamination effects.

What are the Advantages of Platinum Resistance Thermometer?

Platinum Resistance Thermometers offer numerous advantages, making them ideal for industrial applications. The platinum element used in PRTs provides a fast thermal response, ensuring accurate and quick temperature measurements. These thermometers excel in both very low temperatures and moderate temperatures, covering a wide temperature scale.

Unlike copper or nickel, the noble metal platinum offers exceptional stability and resistance to corrosion. The standard platinum resistance thermometer (SPRT) is renowned for its high accuracy, thanks to its precise RTD resistance characteristics.

The coil design of PRTs enhances their sensitivity and reliability, making them a preferred choice for demanding industrial environments. Additionally, comprehensive product manuals ensure easy installation and maintenance, further enhancing their practicality and effectiveness.

What is the Temperature Range of 100 ohm Platinum RTD?

A 100 ohm Platinum RTD (PT100) typically measures temperatures from -200°C to 850°C. Its nominal resistance at 0°C is 100 ohms, following a defined resistance relationship. Industrial RTDs with ceramic or PVC sheaths can withstand higher temperatures. The RTD’s resistance increases predictably with temperature, allowing accurate readings across this extensive range.

What is a Pt100 Temperature Sensor?

A PT100 temperature sensor is a type of platinum resistance thermometer (RTD) that uses a platinum wire with a resistance of 100 ohms at 0 degrees Celsius.

The resistance of the wire changes with temperature, allowing for accurate temperature measurement in a range of applications.

What are the Types of RTD Sensors?

There are several types of RTD sensors commonly used, but the most popular type of RTD is a Pt100 or Pt1000 temperature sensor.

PT100: It uses platinum wire with a resistance of 100 ohms at 0 degrees Celsius
PT1000: Similar to PT100, but with a resistance of 1000 ohms at 0 degrees Celsius

The main difference between PT100 and PT1000 temperature sensors lies in their resistance values. PT100 and PT1000 are both types of platinum resistance temperature detectors (RTDs), which means they are made of platinum wire and their resistance changes with temperature.

The PT100 sensor has a resistance of 100 ohms at 0 degrees Celsius and follows a defined resistance-temperature relationship. It is commonly used in applications where high accuracy is required, such as scientific research, industrial process control, and laboratory equipment. PT100 sensors offer a higher resolution and greater sensitivity to temperature changes due to their smaller resistance change per degree Celsius.

On the other hand, the PT1000 sensor has a resistance of 1000 ohms at 0 degrees Celsius. PT1000 sensors are typically used in applications where a higher resistance is preferred. They are often chosen for their larger resistance change per degree Celsius, which can improve measurement accuracy in certain temperature ranges. PT1000 sensors are commonly found in HVAC systems, building automation, and general temperature monitoring applications.

When selecting between PT100 and PT1000 sensors, it is essential to consider the specific temperature range, accuracy requirements, and compatibility with the measurement system to ensure accurate and reliable temperature measurements.

What is an Ambient Air Temperature Sensor?

An Ambient Air Temperature Sensor is a device that measures the temperature of the surrounding air. It helps determine the temperature in the environment where it is installed, providing information for various purposes such as offices, HVAC systems, climate control systems in cars or weather monitoring equipment.
