电接点双金属温度计WZPK2-375SA 供应
产品介绍(中文)
WZPK2-375SA电接点双金属温度计是一种用于中低温测量的现场检测仪表,广泛应用于工业生产过程中的温度监控与控制。该温度计能够直接测量液体、蒸汽和气体介质的温度,测量范围为-80℃至+500℃。
产品特点
-
直观显示:现场显示温度,读数清晰方便。
-
自动化控制:配备电接点装置,能够在温度达到预设上下限时自动触发继电器动作,实现自动控制和报警功能。
-
耐用性强:采用不锈钢材质的保护管和外壳,具有良好的耐腐蚀性和耐压性能。
-
多种结构形式:可满足不同安装需求,适应多种工业环境。

Product Introduction (English)
The WZPK2-375SA Electric Contact Bimetal Thermometer is a field detection instrument designed for measuring medium and low temperatures. It is widely used in industrial production processes for temperature monitoring and control. This thermometer can directly measure the temperature of liquids, steam, and gas media within a range of -80℃ to +500℃.
Features
-
Intuitive Display: The temperature is displayed on-site, making it easy to read.
-
Automated Control: Equipped with electric contact devices, it can trigger relay actions when the temperature reaches preset upper or lower limits, enabling automatic control and alarm functions.
-
Durability: Made with stainless steel protection tubes and casings, it offers excellent corrosion resistance and pressure resistance.
-
Adaptable Structure: Available in various structural forms to meet different installation requirements and adapt to diverse industrial environments.
-
Safety and Reliability: Long service life, with a protection rating of IP55 to effectively prevent dust and water ingress.
Working Principle
Based on the thermal expansion principle of bimetallic strips, the thermometer uses two metal strips with different expansion coefficients welded together. When the temperature changes, the bimetallic strip deforms and bends, causing the pointer to rotate and display the temperature on the dial. When the pointer contacts or disconnects from the preset upper or lower limit contacts, it triggers the relay in the circuit to achieve automated control.
Technical Parameters
-
Accuracy Class: 1.5.
-
Thermal Response Time: ≤40 seconds.
-
Electrical Parameters: Rated power 10VA, maximum working voltage 220V, maximum working current 1A (inductive load).
-
Operating Environment: Temperature range -25℃ to +55℃, relative humidity ≤85%.
