STR-DCW无线测温装置

仪表通过无线电查询无线传感器温度信息,通过LCD屏显示,并实时把温度信息通过485通讯上传到后台系统。通过连续监测高压开关柜与断路器的接触点运行温度,可确定母线排与触头的温度升高程度,当发生超温时,监测仪发出报警指示,从而避免由于母线排或触头温升过高而造成烧毁等严重事故。

二、技术性能指标:

1、工作电源:AC/DC 110V~220V±10%   50Hz

2、工作环境:温度-10℃~55℃;湿度≤75%RH;海拔高度≤3000m

3、抗电强度:外壳与端子间大于AC2000V。

4、绝缘性能:外壳与端子间大于100MΩ。

5、报警输出:无源,阻性负载,触点容量AC220V 5A

6、在线测温点数:3点、6点、9点、12点(下单指定)

7、传感器安装方式:平板式、表带式、平板感应取电、环型感应取电(下单指定)

8、采集点和接收器距离:≤15米

9、Rs485通讯功能:上传在线温度参数;遵守MODBUS-RTU协议

10、报警数据记录功能:对超温报警进行记录,格式为年月日几时几分

11、无线温度传感器电池使用寿命:5~8年(默认每5分钟测试发送一次数据,温度变化超过1℃即时5秒

发送一次)

12、感应取电传感器:使用寿命大于10年 20A电流启动
