Industrial Dual-element Platinum RTD Sensor WRNK-842n*i
The WRNK-842n*i dual-element platinum resistance temperature detector is engineered for industrial environment monitoring, featuring modular construction for precise measurement and stable signal transmission. Equipped with two independent platinum sensing elements, this device enables simultaneous multi-point temperature acquisition or redundant backup configurations, significantly enhancing system reliability.
Constructed with 304 stainless steel housing featuring polished and anti-oxidation surface treatment, the sensor incorporates high-purity platinum wire elements. The aluminum oxide ceramic insulation layer effectively isolates electromagnetic interference. The tapered probe tip design ensures durable operation in both liquid and gaseous media. Dual-layer silicone gaskets at the cable entry provide robust environmental protection.
With a broad operational range from -50℃ to +500℃, dual-channel outputs maintain independent deviation within ±0.15% of full scale. The element achieves rapid response time <8 seconds (in liquid media) and repeatability error ≤0.05%. Standard 2-meter double-shielded cable can be customized to required lengths. Ideal for HVAC systems, laboratory thermal equipment, and food processing machinery, particularly excelling in scenarios requiring continuous monitoring and data comparison.
Installation utilizes standardized thread interfaces supporting horizontal or vertical mounting. Periodic zero-point calibration is recommended. When used with dedicated junction boxes, the device enables centralized multi-channel signal management. All units undergo 72-hour burn-in testing prior to shipment to ensure long-term stability. Optional extension rods are available for customized immersion depth requirements.
