Diode switched front end for guided wave radar level transmitter |
摘要 |
A guided wave radar level measurement instrument comprises a probe defining a transmission line for sensing material level. A pulse circuit is connected to the probe for generating pulses on the transmission line and receiving reflected signals from the transmission line. The pulse circuit comprises a pulse generator for generating a transmit pulse, a bridge circuit having a diode switched front end connected between the pulse generator and a differential circuit. The transmission line is connected to one side of the differential circuit. Generated pulses from the pulse generator are supplied to both sides of the differential circuit and reflected signals from the transmission line are supplied to one side of the differential circuit. |
