【English Product Introduction】
The WPK2-225SA Explosion-Proof Thermocouple is a specialized temperature monitoring solution engineered for chemical processing environments with potential combustible atmospheres. Its advanced design combines measurement accuracy with exceptional operational reliability in hazardous conditions.
Featuring a unitary explosion-proof enclosure constructed from corrosion-resistant stainless steel, the device incorporates multi-layer sealing technology to prevent ingress of external contaminants. The platinum resistance temperature detector (PRTD) core ensures precise measurement across a broad range of -200℃ to +500℃, delivering ±0.5%FS typical accuracy. Flexible installation is enabled through standardized connection interfaces including flange and threaded joints, compatible with DN15-DN50 process connections.
Safety engineering focuses on flame-path containment technology, where potential internal sparks are completely isolated within reinforced chamber structures. Anti-static surface treatment coupled with IP65 rating provides reliable protection against moisture, particulate matter, and mild chemical exposure. Vibration-resistant construction maintains measurement stability under dynamic conditions up to 55Hz frequency and 0.15mm amplitude.
This instrument excels in critical chemical applications such as distillation columns, polymerization reactors, and hazardous material storage systems. Ergonomic design elements include a rotatable terminal housing and 360° readable dial interface for enhanced field serviceability. Customizable mounting brackets and extension cables accommodate complex piping configurations.
Comprehensive technical support covers device selection guidance and installation consultancy. The product is backed by a 12-month quality assurance program, supported by responsive maintenance teams to ensure continuous operational performance throughout the equipment lifecycle.
