Its compact design and vibration resistance make it ideal for installation in confined spaces or high-vibration environments like compressor stations and pumping units. The product is commonly applied in petrochemical plants for crude oil heating systems, in pharmaceutical factories for sterilization process control, and in food processing facilities for pasteurization temperature supervision. The corrosion-resistant housing ensures long-term reliability even when exposed to harsh industrial atmospheres. 228
技术优势
The WZPK-503S features excellent thermal response characteristics with typical reaction time under 15 seconds, providing real-time temperature feedback for process control. The hermetically sealed casing achieves IP65 protection level, effectively preventing moisture and dust ingress. With its durable stainless steel construction and precision-machined components, this temperature instrument maintains measurement accuracy throughout extended service periods. The clear dial display with anti-parallax design facilitates easy reading from various angles, while the adjustable probe length (available from 50mm to 2000mm) allows customization for different installation requirements. 1023
产品差异化
Compared with conventional thermometers, this electrical contact version adds reliable switching functionality without requiring external power supply. The snap-action contacts provide clean switching signals to control circuits, eliminating contact bounce that could cause erratic operation. Manufacturers have optimized the mechanical structure to minimize hysteresis, ensuring repeatable switching accuracy within ±1.5% of span. For maintenance convenience, some models feature a removable core design that enables sensor replacement without process shutdown. These thoughtful engineering details make WZPK-503S a cost-effective solution for industrial temperature regulation. 317
