Product Overview
The movable thermal resistor WZP-421 is a precision temperature sensor designed for industrial applications. Featuring stainless steel protection tubes and platinum sensing elements, it measures temperatures from -200°C to 500°C in liquids, vapors, gases, and solid surfaces. Its modular design allows flexible installation with options for vibration-resistant configurations and quick maintenance. Ideal for petrochemical, power generation, and metallurgical industries, it delivers fast thermal response (typically 5s) and robust pressure resistance.114
Key Features
Equipped with spring-loaded sensing elements, the WZP-421 minimizes measurement drift caused by mechanical shocks. The dual-wire winding technique on insulated frames ensures uniform temperature gradient detection. Customizable protection tubes (1Cr18Ni9Ti/0Cr18Ni12Mo2Ti) accommodate corrosive environments, while IP-rated junction boxes (splash-proof/waterproof) enhance field reliability. Dual-element versions are available for redundant monitoring systems.212
Specifications
With a measuring range of -200°C to 420°C (Pt100), its accuracy reaches ±(0.15+0.002|t|)°C (-200~650°C). Insulation resistance exceeds 100MΩ (10-100VDC), and maximum allowable current is 5mA (ΔT≤0.3°C). The thermal time constant T0.5 is ≤30s (standard), with minimum insertion depth at 8-10 times the tube diameter. Pressure rating up to 10MPa suits pipeline and vessel installations.425
Applications
Designed for dynamic environments requiring positional adjustments, it excels in reactor monitoring, steam line inspections, and hygienic food processing. Its stable performance meets long-term nuclear plant operations. Compatible with DCS, PLCs, and chart recorders, it provides linear resistance-to-temperature output via direct copper wiring.1522
Customization & Support
Multiple configurations include 12mm/16mm tube diameters and 300-900mm lengths. Three-wire connection eliminates lead resistance errors, with optional flanges/threads for mounting. Thin-film or sheathed elements are available for specialized rapid-response requirements.517
