Product Introduction: Explosion-Proof Platinum RTD WZPK2-136SA
The WZPK2-136SA explosion-proof platinum resistance thermometer delivers reliable temperature measurement in hazardous environments containing combustible substances. Engineered for industrial applications requiring both precision and safety, this robust sensor combines advanced thermal detection technology with explosion containment features.
Key Advantages
-
Intrinsic Safety Design
Multi-layer containment structure with precision-machined flame paths effectively prevents internal energy propagation. The stainless steel housing with corrosion-resistant coating maintains integrity under continuous thermal cycling.
-
Measurement Consistency
High-stability platinum sensing element achieves ±0.12% repeatability across the operational range. Vibration-resistant construction minimizes mechanical stress on sensitive components.
-
Environmental Durability
Sealed terminal compartment with double O-ring protection resists moisture ingress. Optional anti-abrasion sheath extends service life in particle-laden atmospheres.
-
Flexible Integration
Modular design supports various process connections (flange/threaded) and output configurations. Pre-calibrated units enable plug-and-play installation with common control systems.
Typical Applications
• Fuel storage tank temperature monitoring
• Chemical reactor thermal management
• Power plant equipment protection
• Pharmaceutical process validation
