This product is a high-performance, compact PT100 platinum resistance temperature detector designed for precision temperature measurement. Its core employs a Class A platinum resistance element with a nominal resistance of 100Ω at 0°C, following a temperature coefficient of resistance of 0.003851Ω/°C, ensuring high measurement accuracy and long-term stability. In accordance with international standards, its permissible deviation is ∆t = ±(0.15 + 0.002×|t|)°C, providing reliable temperature data over the conventional measurement range of -50°C to +450°C.

The detector features a compact design with a Φ3 mm 316 stainless steel probe stem, an effective length of 100 mm, and is equipped with an external G1/4 threaded mounting connection for easy installation and an internal G1/4 thread for the lead wire outlet. Its three-wire (A+) connection scheme effectively eliminates measurement errors caused by lead resistance. The product offers an ingress protection rating of IP65, which can be upgraded to IP67 with the addition of a sealing gasket, making it suitable for various industrial and equipment internal environments. As a temperature sensing component of Shanghai Shudun Intelligent Technology Co., Ltd., this detector can be integrated into various intelligent monitoring or safety systems to enable real-time temperature detection and feedback for critical areas.
