WZPK-204U Thin-film Platinum RTD Product Introduction
The WZPK-204U thin-film platinum RTD is a high-precision temperature sensing device developed with advanced deposition technology for industrial process control applications. By utilizing nanoscale platinum film uniformly coated on ceramic substrates through physical vapor deposition, this sensor delivers exceptional temperature linearity and measurement consistency under challenging operating conditions.
Featuring 316L stainless steel armored construction with high-purity magnesium oxide insulation, the rugged probe achieves IP67 ingress protection rating and enhanced vibration resistance. The compact design allows minimum outer diameter of 3mm with customizable insertion lengths from 50mm to 2000mm. Operational temperature range spans from -50℃ to +600℃, delivering ±0.15% measurement accuracy in standard industrial environments and long-term stability within 0.05% annual drift.
Notable technical features include optimized thermal response characteristics with τ0.5 time reduced to 1.5 seconds in liquid media, enabling precise tracking of rapid temperature fluctuations. The dual-independent sensing elements configuration supports redundant measurement or dual-channel data acquisition for critical processes. Full-welded hermetic sealing combined with specialty alloy sheathing materials ensures reliable performance in corrosive, humid, and dusty environments.
This temperature sensor excels in petroleum refining units, thermal power generation systems, and food processing lines, particularly suitable for temperature monitoring in polymerization reactors and fluid transfer pipelines requiring precise thermal control. With multiple process connection options (flange, thread, compression fitting) and customizable terminal housings, it seamlessly integrates into existing industrial automation infrastructures.
