表壳采用304不锈钢一体成型工艺，表盘配备钢化玻璃视窗，防护等级达到IP65，可耐受轻度粉尘、水雾及机械振动。感温管长度支持50mm至500mm定制，适配不同深度的安装环境。产品工作温度覆盖-50℃至400℃范围，基本精度控制在量程的±1.5%以内，接点容量满足AC220V/3A或DC24V/5A的常规电气负载要求。

该型号适用于热力管网、食品加工设备、暖通系统等需要本地显示与远程控制协同工作的场景。安装方式支持轴向、径向和万向型三种结构，特殊环境可提供隔爆型选配方案。日常维护仅需定期清除表体积尘并检查接点氧化情况，传动机构采用全封闭设计，有效延长使用寿命。

【Product Introduction in English】

The WZPK-235S Electrical Contact Bimetal Thermometer is a mechanical instrument designed for industrial temperature monitoring and control. Combining bimetal sensing technology with contact signal output, it provides reliable solutions for temperature-sensitive applications requiring automated responses. Featuring optimized structural design and material selection, this product delivers essential temperature measurement while enabling preset trigger points for system integration.

At its core lies a high-performance bimetal sensing element, precision transmission mechanism, and adjustable contact system. The multi-layer composite metallic sensing element drives pointer rotation through thermal expansion/contraction, providing clear analog display. The dual-contact module allows independent setting of upper/lower limits via external calibration knobs, generating switch signals compatible with PLCs, alarms, or actuators.

Constructed with 304 stainless steel housing and toughened glass window, the IP65-rated enclosure resists dust ingress and water spray. Probe lengths from 50mm to 500mm accommodate various installation depths. Operating within -50℃ to 400℃ range, it maintains ±1.5% full-scale accuracy. Contact ratings support AC220V/3A or DC24V/5A loads for common control circuits.

Ideal for heat exchange networks, food processing equipment, and HVAC systems requiring local indication with remote control. Available in axial, radial, or adjustable mounting configurations, with explosion-proof variants for hazardous areas. Maintenance involves routine dust removal and contact inspection, while sealed transmission mechanisms ensure long-term durability.
