Product Description
The WZPK-505S explosion-proof thermocouple is engineered for temperature measurement in hazardous environments containing flammable gases or combustible dust. Its intrinsically safe design ensures reliable performance in petrochemical plants, pharmaceutical reactors, and other critical process applications.
Structural Features
-
Explosion Containment Chamber
Reinforced alloy housing with flame-path barriers isolates potential ignition sources. The segregated terminal compartment prevents spark propagation between wiring connections and sensing elements.
-
Sensing Assembly
Duplex-sheathed thermocouple elements encapsulated in alumina ceramic insulators deliver stable output. The armored construction withstands vibration and thermal shock while maintaining measurement accuracy across -200℃~+800℃.
-
Environmental Protection
Corrosion-resistant coating and IP65-rated enclosures protect against dust ingress and water jets. Tapered thread joints with metal-to-metal sealing ensure long-term integrity in corrosive atmospheres.
-
Installation Flexibility
Configurable with NPT/G threaded, flange-mounted, or compression fittings. Customizable immersion lengths (80mm-2000mm) accommodate various vessel geometries and process connections.
