About Us

Xi'an Tongzida Technology Co., Ltd. has overcome the challenges of high-end intelligent sensor chip processing and manufacturing, such as microsensor manufacturing technology, special packaging technology, and multi-sensor integration methods, to create a comprehensive sensor manufacturing and application enterprise centered around "core sensitive chips+microsensors+testing systems+analysis software".

The company has established a thin film temperature sensitive chip design, processing, packaging, and testing platform, and has built an automated production line for thin film temperature sensor chips covering room temperature, high temperature, and ultra-low temperature. Obtained IS09001 quality management system, ROSH, and CE certification. As a professional platinum resistor manufacturer, our thin film platinum resistor series adopts advanced technology, complies with IEC60751 standard, has a temperature coefficient of 3850ppm/℃, covers a wide temperature range of -200 ℃~+850 ℃, with an accuracy of ± 0.01 Ω (1/30B level), and long-term stability drift ≤ 0.04%. We offer customized options for multiple sizes (1.2mm~4.0mm) and lead materials (platinum nickel/silver nickel/pure platinum, etc.), with a response time of up to 0.05 seconds, vibration resistance of 40g, and impact resistance of 100g, suitable for high demand scenarios such as industrial, medical, automotive, and aerospace. Support vacuum packaging and exclusive solutions, empowering precise temperature measurement with excellent performance!
