FAQs
1. What is a PT100 Sensor?
A PT100 Sensor is a platinum Resistance Temperature Detector (RTD) with a nominal resistance of 100 ohms at 0°C. It measures temperature by detecting the predictable change in the electrical resistance of platinum as temperature changes. PT100 sensors are widely used for accurate and stable industrial temperature measurement and process control.
2. What is the accuracy of this PT100 Sensor?
This model provides Class A accuracy according to IEC 60751, offering a tighter permissible measurement tolerance than Class B PT100 sensors. Class A is therefore well suited to applications requiring improved temperature measurement precision, repeatability, and process control.
3. What is the temperature range of the Aavad PT100 Sensor?
The standard operating range of the Aavad PT100 Sensor is -50°C to +400°C, making it suitable for a wide variety of industrial process measurement, machinery monitoring, HVAC, chemical processing, pharmaceutical applications, and general temperature control systems.
4. Why is a 3-Wire PT100 preferred?
A 3-wire PT100 configuration compensates for the resistance introduced by the connecting lead wires, significantly reducing lead-resistance measurement error compared with a basic 2-wire arrangement. This makes 3-wire RTDs a common choice for industrial temperature measurement and longer cable runs where improved measurement accuracy is required.
