Frequently Asked Questions

Q: What is an RTD PT100 thin film temperature sensor and how does it work?

A: An RTD (Resistance Temperature Detector) PT100 sensor works by measuring the change in electrical resistance of a platinum element as temperature changes. The "PT100" designation means the sensor has a resistance of 100 ohms at 0°C. The thin film design deposits the platinum element onto a ceramic substrate, resulting in a compact, highly accurate sensor ideal for tight spaces and precision measurement applications.

Q: What is "Class A" accuracy for a PT100 sensor?

A: Class A is the highest standard accuracy class for PT100 RTD sensors, as defined by international standards (IEC 60751). A Class A PT100 sensor has a tolerance of ±(0.15 + 0.002|t|)°C, making it suitable for demanding laboratory, industrial, and precision measurement applications where reliability is critical.

Q: What devices are these PT100 sensors compatible with?

A: These PT100 thin film sensors are compatible with a wide range of measurement and control systems, including PLCs (Programmable Logic Controllers), temperature data loggers, Arduino/Raspberry Pi setups with appropriate RTD interface modules, PID controllers, and other industrial or hobbyist measurement equipment that supports PT100 RTD inputs.

Q: Can these sensors be used in both very cold and very hot environments?

A: Yes. These Class A PT100 sensors cover a wide operating range from -50°C (-58°F) all the way up to +400°C (752°F), making them suitable for applications ranging from refrigeration and cold storage monitoring to high-temperature industrial processes.
