温度传感器芯片的测温范围为-55～150℃，测温精度为±2℃。数字故障指示器每秒钟测量一次温度，有报警时立即上报，无报警时每1～5分钟主动上报，或被数据采集器或站内后台机巡检。数字故障指示器每1～5分钟测量一次温度并主动上报，或被数据采集器或站内后台机巡检。
The temperature measurement range of temperature sensor chip is - 55 - 150 C, and the accuracy of temperature measurement is (+2 C). The digital fault indicator measures the temperature once a second, reports immediately when there is an alarm, reports actively every 1-5 minutes when there is no alarm, or is inspected by the data collector or the background computer in the station. The digital fault indicator measures the temperature once every 1-5 minutes and reports it actively, or is inspected by the data collector or or the background computer in the station.
为了测电缆头的温度，电缆型“四遥”数字故障指示器还可以引出带高温屏蔽线的温度探头，用高温扎带将温度探头捆扎在电缆头上。
In order to measure the temperature of cable head, the cable type "four remote" digital fault indicator can also lead out the temperature probe with high temperature shielding wire, and tie the temperature probe on the cable head with high temperature bandage.
