工作原理
該溫度計基于雙金屬片的熱膨脹原理。雙金屬片由兩種不同膨脹系數(shù)的金屬片疊焊而成,當(dāng)溫度變化時,雙金屬片會產(chǎn)生彎曲變形,帶動指針轉(zhuǎn)動,從而在表盤上顯示溫度值。當(dāng)指針與預(yù)設(shè)的上下限電接點接觸或斷開時,會觸發(fā)電路中的繼電器動作,實現(xiàn)自動化控制。

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%.
