WZP-621 Thin-film Platinum RTD Product Introduction

The WZP-621 series assembled thin-film platinum RTD is a high-precision temperature measurement component specifically designed for industrial process control applications. Utilizing advanced thin-film deposition technology, the platinum sensing element is meticulously bonded to a ceramic substrate and integrated with a proprietary protective sleeve structure. This configuration ensures stable and reliable temperature signal acquisition across a broad operating range from -200℃ to +500℃. The compact design and simplified installation process make it suitable for temperature monitoring in diverse industrial environments.

The core sensing element employs high-purity platinum material processed through vacuum deposition, coupled with a dual-layer sealing mechanism that effectively isolates moisture and corrosive substances. Proprietary elastic contact technology ensures reliable thermal transfer between the sensing element and protective sleeve while maintaining mechanical durability. The protective sheath is available in stainless steel, Hastelloy, and other specialized alloys to accommodate various media characteristics. The modular assembly design facilitates field maintenance and element replacement, significantly reducing lifecycle maintenance costs.

In terms of operational performance, this product series demonstrates exceptional long-term stability with annual drift controlled within 0.05%. The optimized thermal conduction structure reduces response time by over 30% compared to conventional designs, making it particularly suitable for capturing rapid temperature fluctuations. Vibration-resistant construction validated through simulated industrial vibration environments (10-2000Hz frequency, 5g acceleration) ensures reliable operation. The housing provides IP65 protection rating for dependable performance in outdoor and harsh operating conditions.

This temperature sensor finds extensive application in reactor temperature monitoring for petrochemical plants, sterilization process control in pharmaceutical equipment, thermal profiling for food processing lines, and overheating prevention in power systems. Customizable lead wire configurations, including optional 4-wire connections, are available to interface with various automation control systems. Our technical support team provides customized selection guidance, installation consultation, and field commissioning services to ensure optimal system integration.
