Introducing the Technology Behind Thin Film Pt100 Sensors
Thin Film Pt100 sensors represent a significant advancement in temperature measurement technology. These sensors utilize a thin layer of platinum deposited on a ceramic substrate, offering superior accuracy and faster response times compared to their wire-wound counterparts. The "Pt100" designation indicates that the sensor is made of platinum (Pt) and has a resistance of 100 ohms at 0°C.
The Manufacturing Process of Thin Film Pt100 Sensors
The production of Thin Film Pt100 sensors involves a sophisticated process that requires precision and expertise. At Tongzida, this process begins with the design of the temperature-sensitive chip. The company has established a state-of-the-art platform for designing, processing, packaging, and testing these chips. This comprehensive approach ensures that each sensor meets the highest standards of quality and performance.
The manufacturing process involves depositing a thin layer of platinum onto a ceramic substrate using advanced sputtering techniques. This method allows for precise control over the thickness and uniformity of the platinum film, which is crucial for achieving accurate temperature measurements. After deposition, the sensors undergo a series of processes, including laser trimming to achieve the desired resistance value and stability.
