中文介绍
WZPK-303S电接点双金属温度计是一种用于测量中低温的现场检测仪表,广泛应用于生产现场对温度需自动控制和报警的场合。该温度计可直接测量各种生产过程中-80℃至+500℃范围内液体、蒸汽和气体介质的温度。其工作原理是利用温度变化带动触点变化,当触点与上下限触点接触或断开时,使电路中的继电器动作,从而实现自动控制和报警。
该温度计具有多种结构形式,可满足不同安装要求。其保护管、节头、锁紧螺栓等均采用1Cr18Ni9Ti材料,表壳经黑色电泳处理,具有良好的防水防腐性能。温度计的外壳能承受距离5米处用喷嘴直径25毫米的水喷射5分钟而不渗水,符合IP65防护等级。
主要技术参数包括:精度等级为1.5级,接点额定功率为10VA,接点最高工作电压为380V或220V,最高工作电流为1A(无感负载)。测温范围为-60℃至500℃,尾管长度可在100至2000mm之间选择,尾管直径根据长度不同分为φ6、φ10、φ12。安装部分螺纹有M16X1.5、M27X2、G1/2、G3/4等多种规格。
English Introduction
The WZPK-303S electric contact bimetallic thermometer is a field detection instrument for measuring medium and low temperatures. It is widely used in production sites where automatic temperature control and alarm are required. This thermometer can directly measure the temperature of liquids, steam, and gaseous media in the range of -80℃ to +500℃ during various production processes. It works by using temperature changes to move the contact points. When the contact points touch or disconnect from the upper and lower limit contacts, the relay in the circuit is activated, thereby achieving automatic control and alarm.
The thermometer is available in various structural forms to meet different installation requirements. Its protective tube, joint, and locknut are all made of 1Cr18Ni9Ti material, and the case is treated with black electrophoretic coating, providing excellent waterproof and corrosion-resistant performance. The thermometer s case can withstand a 5-minute water spray from a nozzle with a diameter of 25mm at a distance of 5 meters without water seepage, meeting the IP65 protection rating.
The main technical parameters include a precision grade of 1.5, a contact rated power of 10VA, a maximum working voltage of 380V or 220V, and a maximum working current of 1A (for non-inductive loads). The temperature measurement range is -60℃ to 500℃, and the tailpipe length can be selected between 100 and 2000mm. The tailpipe diameter varies depending on the length, with options of φ6, φ10, and φ12. There are also various installation thread specifications, such as M16X1.5, M27X2, G1/2, and G3/4.
