Troubleshooting method: 1. Resistance method a. Power fuse, excitation insurance on and off; b. Signal cable, excitation cable on and off; c. excitation coil on and off and resistance; d. Insulation resistance of the excitation coil to the ground; e. Symmetry measurement; f. Insulation resistance of electrode to ground; g. Resistance of power transformer.
2. Current method measuring output current, excitation current 3. Voltage method to determine the working power 4. Alternative methods such as the exchange of the converter 5. Analog signal method Using the analog signal generator to provide flow signal to test the flow sensor.
6. The waveform method is familiar with testing keypoint waveforms on a line basis.
Radio modems are dedicated to transfer data between two or more locations. GrandComm`s radio modems operate in VHF and UHF frequency band and can cover a distance of over 50 kilometers. The radio modems can provide programmable serial baud rates from 1200bps to 115200bps.
GrandComm`s radio modem products are designed to industrial standards and well-suited for SCADA, telemetry and process control applications in wireless environment. The radio modem can communicate data of remote control signals, telemetry signals from a transducer, computer`s RS232 port, GPS position signals, or a digital terminals.
