Product Overview
The WZPK-503S explosion-proof industrial RTD is specifically engineered for temperature measurement in hazardous gas environments within petrochemical, pharmaceutical, and metallurgical industries. Featuring a specialized explosion-proof housing, this sensor accurately converts temperature variations into electrical signals for process monitoring and control systems. Its robust construction ensures reliable performance when measuring gases, liquids, or steam temperatures under demanding conditions, with notable resistance to vibration and corrosive media. The compact design facilitates integration with various automation equipment. 39
Design Features
At the core of WZPK-503S lies a precision temperature sensing element housed within a multi-layered protective assembly. The die-cast aluminum junction box incorporates intrinsic safety barriers to contain potential ignition sources. A spring-loaded sensing module enhances mechanical stability during operation, while optional armored sheaths extend durability in abrasive flows. The product s triple-wire connection topology minimizes measurement errors caused by lead resistance. Field-serviceable components and standardized mounting interfaces simplify installation in confined spaces typical of chemical processing plants. 1922
Technical Specifications
Covering -200°C to +500°C range, this RTD delivers consistent linear output throughout industrial temperature cycles. Customizable immersion lengths (75mm minimum) accommodate diverse vessel geometries, with flange/thread adapters for pressurized pipelines. The IP65-rated enclosure withstands washdown procedures and outdoor exposure. Particularly suited for Zone 1/2 hazardous areas containing explosive mixtures, its thermal management design prevents external surface temperatures from exceeding safety thresholds. Optional FEP-coated probes are available for highly corrosive media such as chlor-alkali processes. 1427
