The transmitter head can be interchanged with a series of radar level gauges. The transmitter head consists of a body and an electronic unit (the).
电子单元由微波单元、信号处理、数据通信、电源及瞬变保护电路板等构成。
The electronic unit consists of microwave unit, signal processing, data communication, power supply and transient protection circuit board.
信号处理卡件(SPC)
Signal processing card (SPC)
SPC卡件包括高性能的信号处理器及通过远程编程保存储罐特定数据集的库存检测器。
SPC card includes high performance signal processor and inventory detector which can store specific data set of storage tank by remote programming.
模拟处理卡件(APC)
Analog processing card (APC)
APC卡件用于模拟输入信号的滤波和多路复用。将模拟电路保留在独立的卡件上,可达到较高的信噪比,从而提高测量精度。
APC card is used for filtering and multiplexing of analog input signals. By keeping the analog circuit on the independent card, a higher signal-to-noise ratio can be achieved, thus improving the measurement accuracy.
温度多路输入卡件(TMC)
Temperature multiplex input card (TMC)
温度多路输入卡件(TMC)用于将6台温度传感器直接连接储罐雷达液位计。
The TMC is used to connect six temperature sensors directly to the radar level gauge of the storage tank.
变速送器接口卡件(TIC)
Transmission interface card (TIC)

Two incoming Zener barriers and two return barriers for 4-20mA current circuit.
用于下位数据采集单元或远传显示单元的单台齐纳安全栅。
A single Zener safety barrier for the lower data acquisition unit or remote display unit.
用于可选的温度多路输入器卡件(TMC)的信号、电源连接件。
Signal and power connector for optional TMC.
继电器输出卡件(ROC)
Relay output card (ROC)
继电器输出卡件(ROC)包括两台继电器,可用于控制外部装置,如阀门、泵、加热盘管等。
The ROC consists of two relays, which can be used to control external devices such as valves, pumps, heating coils, etc.
