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, also known as a platinum RTD (Resistance Temperature Detector), is a type of temperature sensor that uses the principle of electrical resistance to measure temperature.
It consists of a thin platinum wire wound into a coil or deposited on a ceramic substrate. The resistance of the platinum wire changes with temperature in a predictable manner.
By measuring the resistance, the temperature can be determined accurately. Platinum RTD sensors offer high accuracy, stability, and repeatability over a wide temperature range. They are commonly used in scientific laboratories, industrial processes, and precision applications where precise temperature measurement is required.
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.
