English Version：
The WZPK2-425SA explosion-proof thermal resistor is an intelligent temperature measurement instrument specifically engineered for chemical industry applications. Featuring a multi-layer composite protection structure and high-strength stainless steel housing, this device effectively isolates combustible media from internal components. Specially processed sensing elements demonstrate anti-permeability characteristics, delivering stable signal output performance in high-pressure and highly corrosive environments.
Equipped with an independently developed temperature compensation system, the device achieves precise measurement across a broad range of -200℃ to +800℃ through digital processing technology, maintaining linear deviation within ±0.3%FS. Modular construction facilitates installation and maintenance, supporting multiple industrial interface standards including flange and threaded connections. The vacuum-sintered thermal sensing unit forms a uniform inert insulation layer between the measuring terminal and protective sleeve, effectively preventing thermal hysteresis.
This product is suitable for petroleum refining, organic synthesis, pesticide production and other scenarios involving Class IIA/IIB explosive gas environments. The stress-relieved armored structure withstands instantaneous impact pressures exceeding 20MPa. Contact components constructed from Hastelloy-ceramic composites resist chemical corrosion within PH2-14 range. Unique vibration damping design maintains 0.1-grade measurement accuracy under 30Hz-2000Hz vibration conditions.
The intelligent terminal box integrates overload protection modules, supporting flexible three-wire/four-wire connections. With IP68 protection rating, it operates continuously at 30-meter underwater depth. Customizable options include Pt100, Cu50 and other graduation types, with probe lengths adjustable from 100mm to 2000mm. Each unit undergoes 168-hour simulated operational testing to ensure signal transmission stability in complex electromagnetic environments.
