PT1000 Class A Temperature Sensor
The PT1000 is a type of temperature sensor, and the term "Class A" refers to its level of accuracy according to standard specifications. Let's break down each part:
PT1000: The PT1000 is a type of resistance temperature detector (RTD) sensor. It is commonly used to measure temperature in various industrial and scientific applications. RTDs are sensors that rely on the principle that the electrical resistance of a metal changes predictably with temperature. PT1000 indicates that this particular RTD has a resistance of 1000 ohms at 0 degrees Celsius.
Class A: The accuracy of an RTD is usually defined by its class, which determines how closely the sensor's actual temperature reading matches the true temperature. The most common classes for RTDs are Class A and Class B.
Class A: PT1000 Class A sensors have a higher level of accuracy. They conform to the International Electrotechnical Commission (IEC) standard IEC 60751, which defines the allowable tolerance for the resistance-temperature curve of the sensor. For Class A PT1000, the tolerance is typically within ±(0.15°C + 0.002*|t|) at 0°C, where |t| is the absolute temperature in Celsius. So, for example, at 100°C, the accuracy would be within ±0.35°C.
Class B: PT1000 Class B sensors have a slightly lower accuracy compared to Class A. The tolerance for Class B PT1000 is typically within ±(0.3°C + 0.005*|t|) at 0°C.
In summary, a PT1000 Class A temperature sensor is a highly accurate sensor that measures temperature using a platinum resistance element with a resistance of 1000 ohms at 0°C, and its accuracy falls within the specified limits of Class A according to the IEC 60751 standard.
