【English Introduction】
The WZPK-133S Explosion-Proof Platinum RTD is a temperature sensing device specifically engineered for industrial applications in hazardous environments with flammable gases. Integrating high-stability platinum sensing elements with corrosion-resistant stainless steel housing and specialized explosion-proof construction, this product delivers reliable temperature measurement while ensuring operational safety. The compact housing design combines mechanical durability with environmental adaptability, making it suitable for long-term deployment in petroleum, chemical processing, power generation, and metallurgical industries.
The core platinum thin-film sensor exhibits exceptional temperature linearity and long-term measurement consistency. Advanced encapsulation technology minimizes measurement deviations caused by mechanical vibrations and medium turbulence. The explosion-proof chamber incorporates multi-layer sealing mechanisms to isolate electrical components from combustible substances, maintaining operational integrity in potentially explosive atmospheres. The terminal compartment features sealed cable entries compatible with various industrial connection standards, facilitating efficient field installation.
With an operational temperature range spanning -200℃ to +500℃, this device supports customizable measurement ranges and mounting configurations. The sensor head accommodates tapered thread or flange mounting options for compatibility with standard industrial interfaces. Built-in electromagnetic interference (EMI) suppression enhances signal transmission stability in environments with variable-frequency drives and high-power electrical equipment. The housing undergoes high-temperature oxidation-resistant treatment, complemented by internal vacuum-sealing technology, to extend service life and reduce maintenance requirements.
