技术描述
WZPK-103U通过双金属片的热膨胀原理工作:当温度变化时,双金属片自由端带动指针偏转,同时触发电接点通断。标度盘直径可选100mm或150mm,精度等级1.5级,热响应时间≤40秒。电气参数方面,接点额定功率10VA,最高工作电压220V(推荐36V以下使用以确保稳定性)。产品无汞害,符合环保要求,且支持抽芯式维护,无需停机即可更换机芯。111320
Product Introduction (English)
The WZPK-103U Bimetal Thermometer with Electrical Contact is designed for industrial temperature measurement and control. Its bimetallic strip sensing element provides accurate readings within -80℃ to +500℃, suitable for liquids, steam, and gases. The clear dial display allows on-site monitoring, while the integrated electrical contacts activate relays for automated temperature regulation or alarms when thresholds are reached. 11217
Key Features
Constructed with stainless steel protection tubes and corrosion-resistant materials, this thermometer ensures durability in harsh environments. The IP55-rated housing offers dust and water resistance, ideal for petrochemical or power plants. The mechanical contact mechanism supports adjustable upper/lower limits with reliable switching performance. Multiple mounting options (axial, radial, or adjustable) accommodate diverse installation needs. 91425
Technical Details
The WZPK-103U operates via thermal expansion: temperature changes deform the bimetallic strip, moving the pointer and triggering contacts. Standard dial sizes are 100mm/150mm with 1.5% accuracy and ≤40s response time. Electrical contacts handle 10VA (220V max; 36V recommended). The mercury-free design is eco-friendly, and the removable core enables maintenance without process interruption. 182228
