Data Logger Considerations
Current CR10X Wiring Panels can accommodate both the CURS100 and the cover associated with the CR10XTCR (reference thermistor for thermocouple measurements). Specifically, the physical configuration of the thermocouple cover, the data logger input terminals, and the terminal input modules allow sufficient room for the cover to be used with the CURS100 attached. In contrast, older CR10TCR covers are not deep enough.
Note: The CR6 (serial number >7501), CR1000X, CR350, CR300, and CR310 data loggers can do current measurements without the CURS100.
Programming
The CURS100 output is measured with VoltDiff Instruction in CRBasic and with Instruction 2 (Differential Voltage) in Edlog. The CURS100 consumes one differential analog input; an adjacent analog ground channel accepts the analog "ground prong" of the CURS100. Not all data logger terminal strips have this sequence on all channels, so please check your data logger's wiring panel to confirm channel assignments, especially if you plan to use multiple terminal input modules.
常见问题解答
CURS100: 1
-
是。使用 CURS100 将传感器的电流信号 (例如： 4 到 20 mA) 转换成电压信号，之后就可以被 CR1000 测量。这个精密的 100-欧姆电阻桥臂用来并联电流信号，允许通过多达 50 mA 的电流，转换成的电压信号可在 ±5000 mV 量程读取。
