WZP PT100 is an industrial thermal resistance. It is used as a sensor for measuring temperature, and it is used in conjunction with display instruments, recording instruments and electronic regulators.

WZP PT100 industrial thermal resistance is the most commonly used temperature detector in the middle and low temperature areas. The main features are high measurement accuracy and stable performance. Among them, the measurement accuracy of platinum thermal resistance is the highest. It is not only widely used in industrial temperature measurement, but also made into a standard reference instrument.

More About WZP PT100

PT100 and RTD are both temperature sensors, but PT100 specifically refers to a type of RTD (Resistance Temperature Detector).

RTD is a type of temperature sensor that works by measuring changes in electrical resistance as temperature changes. PT100 RTDs have a resistance of 100 ohms at 0 degrees Celsius, which makes them a common choice for temperature measurement in industrial and scientific applications.

So, PT100 is just one type of RTD sensor that has a specific resistance value at a specific temperature.

A PT100 temperature sensor is a type of temperature sensor that measures temperature by detecting changes in electrical resistance. Specifically, it is an RTD (Resistance Temperature Detector) that has a resistance of 100 ohms at 0 degrees Celsius.

As the temperature changes, the resistance of the sensor also changes in a predictable way, allowing the sensor to accurately measure the temperature. PT100 sensors are commonly used in industrial and scientific applications where precise temperature measurement is important.

PTC and PT100 are both types of temperature sensors, but they work in different ways.

PTC stands for Positive Temperature Coefficient, and it is a type of thermistor that increases in resistance as temperature increases. In other words, the resistance of a PTC sensor goes up as the temperature it is measuring goes up. PTC sensors are commonly used in applications such as over-temperature protection in electronic circuits.

PT100, on the other hand, is a type of RTD (Resistance Temperature Detector) that has a specific resistance value of 100 ohms at 0 degrees Celsius. As temperature changes, the resistance of a PT100 sensor changes in a predictable way, allowing it to accurately measure temperature. PT100 sensors are commonly used in industrial and scientific applications where precise temperature measurement is important.

So, the main difference between PTC and PT100 is that PTC sensors increase in resistance as temperature increases. While PT100 sensors have a specific resistance value at a specific temperature and change resistance in a predictable way as temperature changes.

Calibrating a PT100 temperature sensor involves comparing its readings to known, accurate temperatures and making adjustments to the sensor’s output to ensure it is reading accurately.

Here are the basic steps for calibrating a PT100 sensor:

  1. Obtain a reference thermometer or other temperature calibration device with a known, accurate temperature reading.
  2. Place the reference thermometer and the PT100 sensor in a controlled environment with a stable temperature.
  3. Wait for the temperature to stabilize and record the readings from both the reference thermometer and the PT100 sensor.
  4. Compare the readings and calculate the difference between the two.
  5. Adjust the output of the PT100 sensor as needed to match the reference thermometer reading.
  6. Repeat the process at several different temperatures to ensure accuracy across a range of temperatures.

It’s important to note that calibrating a PT100 sensor can be a complex and technical process. And it may be best to consult with a professional or use specialized calibration equipment to ensure accurate results.

Here are some key differences between RTD temperature sensors and thermocouples:

RTD Temperature SensorsThermocouples
Higher accuracy and repeatability;
Smaller temperature range;
Less susceptible to EMI;
More stable over time and exhibit less drift;
Require a stable, regulated power source to operate;
Can be more expensive;		Wider temperature range;
Can operate in harsher environments;
Do not require a power source to operate;
Can be less expensive;
More susceptible to EMI;
Can exhibit more drift and require frequent calibration;
