光敏继电器L SR ？
The Buchholz Relay is used as a protective device sensitive to the effects of dielectric failure inside the equipment.
作为安全装置，布赫继电器对于设备内的电介质故障是非常敏感的。
RFID tags can, for example, be connected to external sensors in order to relay valuable information about sensitive cargo in transit, such as temperature and humidity.
例如，RFID标签可以通过外部的传感器进行读取，以用来在运输过程中传递对环境敏感物品有价值的信息，例如温度和湿度。
We should always check the high voltage DC power supply within the current relay, time relay setting value is correct, control is sensitive.
应经常检查高压直流电源内电流继电器，时间继电器的整定值是否正确，控制是否灵敏。
