The WZPK2-126SA Explosion-Proof Thermocouple is specifically engineered for temperature measurement in chemical processing environments where combustible gases or dust may be present. Featuring intrinsic safety design, this device ensures reliable operation in hazardous areas while maintaining precise temperature monitoring capabilities.
Constructed with modular architecture, the sensor probe and junction box adopt threaded connection for physical isolation. The armored element utilizes 316L stainless steel with enhanced corrosion resistance, capable of withstanding exposure to common chemical media. Specially encapsulated sensing components deliver responsive measurement while maintaining structural integrity under vibrational conditions. The sealed terminal chamber incorporates multi-layer gaskets and anti-loosening terminals to ensure durable electrical connections.
This instrument provides temperature measurement across a broad range from -200℃ to +500℃, with typical accuracy within ±1.5℃ under standard conditions. Flexible installation options include threaded and flanged connections, accommodating diverse process requirements. The surface-treated housing features uniform protective coating to resist high-temperature oxidation. A self-cleaning tapered tip design minimizes measurement deviations caused by media crystallization or buildup.
Ideal for critical applications including distillation column monitoring, reactor temperature control, and pipeline heating systems in petrochemical plants. The device has demonstrated proven performance in chlor-alkali production, coal chemical processing, and specialty chemical manufacturing. Users are advised to select appropriate sheath materials based on specific media characteristics, perform regular insulation resistance checks, and employ protective sleeves in high-temperature environments to optimize service life.
Maintenance considerations include periodic calibration verification and visual inspection of sealing surfaces. When installed in high-pressure systems, proper torque application during assembly is recommended to maintain structural integrity. The product s design accounts for thermal expansion effects, ensuring stable performance across operational temperature fluctuations.
