产品介绍
WSSX-483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与控制设备。它能够直接测量生产过程中-80℃至+500℃范围内的液体、蒸汽和气体介质温度。该温度计具备现场显示功能,操作人员可以直观地读取温度数据,同时它还配备了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触发警报或切断电路,从而实现自动控制。
WSSX-483电接点双金属温度计的设计注重安全性和可靠性,使用寿命长,且有多种结构形式可供选择,能够满足不同用户的安装和使用需求。其工作原理是基于双金属片的热膨胀特性,当温度变化时,双金属片会带动触点移动,当触点与预设的上下限触点接触或断开时,触发电路中的继电器动作,从而实现自动控制和报警。
在技术参数方面,该温度计的标度盘公称直径为100毫米,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。正常工作的大气条件为温度-25℃至+55℃,相对湿度不超过85%。此外,其电气参数包括额定功率10VA,最高工作电压220V交流或24V直流,最大允许电流为0.7A。
Product Introduction
The WSSX-483 Electric Contact Bimetal Thermometer is a widely used temperature measurement and control device in industrial production sites. It can directly measure the temperature of liquids, vapors, and gaseous media within the range of -80℃ to +500℃. This thermometer features on-site temperature display, allowing operators to read temperature data intuitively. It also has an automatic power cut-off and alarm function, which can trigger alarms or cut off circuits when the temperature reaches the preset upper or lower limits, thereby achieving automatic control.
The WSSX-483 Electric Contact Bimetal Thermometer is designed with a focus on safety and reliability, offering a long service life. It is available in various structural forms to meet different installation and usage requirements. The working principle of this thermometer is based on the thermal expansion characteristics of bimetallic strips. When the temperature changes, the bimetallic strip moves the contact point. When the contact point touches or disconnects from the preset upper or lower limit contacts, it triggers the relay in the circuit to act, thus achieving automatic control and alarm.
In terms of technical parameters, the thermometer has a dial diameter of 100 mm, a precision grade of 1.0 or 1.5, a thermal response time of no more than 40 seconds, and a protection rating of IP55. The normal working atmospheric conditions are a temperature range of -25℃ to +55℃ and a relative humidity of no more than 85%. Additionally, its electrical parameters include a rated power of 10VA, a maximum working voltage of 220V AC or 24V DC, and a maximum allowable current of 0.7A.
