Product Overview
The WZPK-103U armored platinum thin-film resistor is a high-performance temperature sensor designed for precise measurement in complex environments. Featuring a thin-film platinum element housed in a stainless steel sheath with high-density oxide insulation, it excels in anti-contamination and mechanical durability. Its compact diameter (3-8mm) and flexible structure allow installation in narrow pipelines or miniaturized equipment, with a temperature range of -50℃ to +200℃. Standard configuration includes B-grade 3-wire system, while A-grade, 2-wire, or 4-wire options are available upon request. Sheath materials default to 1Cr18Ni9Ti or 304 stainless steel, with 316 stainless steel as a customizable alternative.113
Key Features
The WZPK-103U stands out for its rapid thermal response (as fast as ≤3s for φ3mm) and measurement accuracy, enabled by imported platinum film technology. The armored construction ensures shock resistance and high-pressure tolerance, ideal for harsh conditions like chemical plants or high-vibration machinery. Multiple installation options (threaded, flanged, or free-mounted) and customizable lengths (with incremental pricing per 10mm extension) enhance adaptability. Copper wires (1m default) guarantee stable signal transmission with Pt100 output, suitable for most industrial temperature zones.5615
Technical Specifications
Operating within -50℃ to +200℃, this model achieves B-class accuracy. Insulation resistance exceeds 100MΩ (tested at 10-100V DC) under 15-35℃/≤80% humidity. The t0.5 response time varies by diameter (e.g., ≤5s for φ4mm). No fixed mount is pre-installed; users may select threaded (M16×1.5) or flanged interfaces. With ≤5mA maximum current, self-heating effects are minimized. The stainless steel sheath resists corrosion, while the氧化絕緣層 ensures electrical safety in wet or dusty environments.41129
Applications
Ideal for rapid-temperature monitoring in reactors, pipelines, or power units, the WZPK-103U’s compact design suits space-constrained scenarios like valve interiors or lab equipment. In oil/gas applications, it withstands corrosive fluids; in food processing, its sanitary materials meet hygiene standards. Compatible with PLCs, data loggers, or displays, it provides real-time inputs for automated systems across industries including metallurgy, energy, and water treatment.2727
