产品英文介绍：

The WZP-212AB thin-film platinum RTD is a precision temperature sensing device manufactured with advanced deposition technology, designed to deliver reliable temperature measurement in industrial automation, HVAC systems, and food/pharmaceutical processing applications. Its core element features a vacuum-sputtered platinum layer on high-grade ceramic substrate, precisely trimmed by laser calibration to achieve exceptional linearity and long-term stability.

Encased in polished 304 stainless steel housing with IP67 protection rating, this sensor demonstrates remarkable mechanical durability and corrosion resistance. The modular design offers flexible installation configurations, including straight probe (3mm-8mm diameter options), 90° angled probe, and flange-mounted variants. Standard 2-meter high-temperature fluoropolymer cables are available with optional Pt100/Pt1000 output, accommodating diverse system integration requirements.

With an extended operational range from -50℃ to +400℃, the device maintains ±0.15℃ basic accuracy at 0℃ reference point. Rapid thermal response (T0.9<0.8s) is achieved through optimized thermal coupling structure, while the proprietary passivation layer effectively resists chemical corrosion in harsh environments. Low self-heating characteristics (0.02mW/℃ typical) ensure measurement integrity during continuous operation. Customizable immersion lengths and process connections enable seamless adaptation to various industrial applications.
