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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is \"Class A\" accuracy for a PT100 sensor?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What devices are these PT100 sensors compatible with?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can these sensors be used in both very cold and very hot environments?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What is an RTD PT100 thin film temperature sensor and how does it work?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"An RTD (Resistance Temperature Detector) PT100 sensor works by measuring the change in electrical resistance of a platinum element as temperature changes.
