WZP-230B Thermal Resistance Product Description
The WZP-230B thermal resistance is a high-precision temperature sensor designed for power plant applications. It utilizes platinum resistance elements (Pt100) to reliably measure temperatures ranging from -200°C to 420°C in liquids, steam, gases, and solid surfaces. The sensing element consists of fine metal wire wound uniformly on an insulated frame, ensuring accurate average temperature detection under thermal gradients. With stainless steel protection tubes (e.g., 1Cr18Ni9Ti) and optional diameters (Φ12mm/Φ16mm), it features fast response (≤90s) and threaded fixation (e.g., M27×2) for easy installation. The IP65-rated junction box enhances durability in harsh environments. Compatible with display instruments and control systems, it is widely used in power generation, petrochemical, and metallurgical industries. 152127

Technical Features
The WZP-230B incorporates a spring-loaded sensing element for superior vibration resistance, ideal for high-vibration power equipment. Its robust construction withstands pressures up to 10MPa (threaded type), with corrosion-resistant protection tubes for high-temperature operation. The thin-film resistor achieves B-grade accuracy (±0.3℃ or ±0.005∣t∣) with long-term stability. Single or dual-element options (dual for redundancy) and adjustable insertion depths (300mm~1000mm) provide installation flexibility. Excellent insulation (≥100MΩ at room temperature) ensures signal integrity in electromagnetic environments. 182329
