电接点双金属温度计WRNR-12 供应
产品介绍(中文)
WRNR-12型电接点双金属温度计是一种广泛应用于工业生产现场的温度测量仪表。它能够直接测量液体、蒸汽和气体介质的温度,适用于-80℃至500℃的温度范围。该温度计采用双金属片作为感温元件,当温度变化时,双金属片会发生形变,从而带动指针转动,实现温度的直观显示。
WRNR-12型温度计具有多种结构形式,能够满足不同工况下的安装需求。其表盘直径为100毫米,读数清晰,便于现场操作人员直接观察。此外,该温度计还具备自动切断电源和报警功能,能够在温度达到预设的上下限时,通过触点动作触发继电器,实现自动控制和报警,确保生产过程的安全性和稳定性。
在性能方面,WRNR-12型电接点双金属温度计的精度等级为1.0级或1.5级,热响应时间不超过40秒,防护等级达到IP55,能够在-25℃至55℃的环境温度和相对湿度不超过85%的条件下正常工作。其设定点误差不超过基本误差限的1.5倍,切换差和切换重复性也均在合理范围内,确保了测量的准确性和可靠性。
Product Introduction(English)
The WRNR-12 type bimetallic thermometer with electrical contact is a widely used temperature measuring instrument in industrial production fields. It can directly measure the temperature of liquid, steam, and gas media within the range of -80℃ to 500℃. This thermometer uses a bimetallic strip as the temperature-sensing element. When the temperature changes, the bimetallic strip deforms, causing the pointer to rotate and providing an intuitive display of the temperature.
The WRNR-12 type thermometer is available in various structural forms to meet the installation requirements of different working conditions. With a dial diameter of 100 millimeters, it offers clear readings that are easy for on-site operators to observe. In addition, this thermometer is equipped with an automatic power cut-off and alarm function. When the temperature reaches the preset upper or lower limit, the contact action triggers a relay to achieve automatic control and alarm, ensuring the safety and stability of the production process.
In terms of performance, the WRNR-12 type bimetallic thermometer with electrical contact has an accuracy class of 1.0 or 1.5, a thermal response time of no more than 40 seconds, and a protection rating of IP55. It can operate normally under environmental temperatures ranging from -25℃ to 55℃ and relative humidity not exceeding 85%. The set-point error does not exceed 1.5 times the basic error limit, and the switching difference and switching repeatability are both within reasonable ranges, ensuring the accuracy and reliability of the measurement.
