【中文产品介绍】

WZP-3212U型电接点双金属温度计是一款专为工业环境设计的温度监测与控制设备，采用双金属传感原理与电接点技术相结合，适用于过程控制系统中温度参数的直观显示与信号输出。产品通过机械结构实现温度测量，无需外部电源即可完成本地指针指示，同时通过可调节电接点实现超温预警或联锁控制功能，兼顾经济性与实用性。

核心特点：

1. ‌双传感协同设计‌：内置精密双金属螺旋元件，通过热膨胀系数差异驱动指针，配合可调节电接点模块，实现温度测量与触点控制双重功能。接触部件采用银合金材质，确保信号传输稳定性。
2. ‌宽域环境适应性‌：表壳采用304不锈钢一体成型工艺，防护等级达IP65，可耐受潮湿、粉尘及轻度腐蚀性环境。工作温度覆盖-50℃至500℃，支持多量程定制，满足不同工况需求。
3. ‌人机交互优化‌：表盘直径80mm，黑色刻度线与白色表盘形成高对比度显示，支持轴向/径向/万向等多种安装朝向。玻璃面板增设聚碳酸酯保护层，提升抗震抗冲击性能。
4. ‌灵活控制配置‌：单接点或双接点可选，触点容量最高达220VAC/1A，可直接驱动小型继电器或参与PLC控制回路。接点位置可通过表盘外置旋钮进行无工具调节。

典型应用场景：
• 暖通空调系统冷媒管路温度监测
• 食品加工设备灭菌温度过程控制
• 注塑成型机模温异常报警
• 压缩空气系统过热保护

我们提供完善的选型指导与技术支持，可根据客户需求定制表壳材质、接点数量、过程连接方式等参数，同时配备三年核心部件质保服务，确保设备长期稳定运行。

【English Product Introduction】

The WZP-3212U Bimetal Thermometer with Electrical Contact is an industrial-grade temperature monitoring solution that combines bimetal sensing technology with adjustable contact switches. This standalone instrument provides both local analog indication and switching functionality without requiring external power supply, making it ideal for process control applications requiring cost-effective temperature management.

Key Features:

1. ‌Dual-Function Mechanism‌: Precision-engineered bimetal coil drives the pointer for visual temperature reading, while adjustable silver alloy contacts provide reliable switching action within ±1.5% full scale accuracy.
2. ‌Robust Construction‌: 304 stainless steel housing with IP65 protection resists moisture, dust, and mild corrosive substances. Operating range spans from -50℃ to 500℃ with customizable scale intervals.
3. ‌Enhanced Readability‌: 80mm diameter dial features high-contrast white-on-black markings with polycarbonate reinforced lens. Available in axial, radial, or adjustable mounting orientations for flexible installation.
4. ‌Versatile Control Options‌: Configurable with single or double SPDT contacts rated for 220VAC/1A. External calibration dial allows contact position adjustment without disassembling the housing.

Typical Applications:
• Overheat protection for hydraulic oil systems
• Temperature interlocks in packaging machinery
• Batch reactor temperature monitoring
• HVAC ductwork thermal cutoffs

Customizable parameters include process connection types (threaded, flange, or stem mount), contact configurations, and dial color schemes. Backed by three-year warranty on core components and technical support for installation optimization.
