Kaidi-R803 High precision radar level meter
Application:
6GHz radar level gauge is suitable for liquid, paste, granule and block material level and non-contact measurement, suitable for changes in temperature, pressure big; there is an inert gas and volatile.
The measurement method of microwave pulse, can work normally in the industrial frequency band range. The beam energy is low, can be installed on all kinds of metal, non-metallic container or pipe, no harm to human body and environment.

2.The Electrical Connection
l The power supply voltage:
| (4~20)mA/HART (Two wire system) | The power supply and the output current signal sharing a two core shield cable. The supply voltage range see technical data. For intrinsically safe type must be a safety barrier between the power supply and the instrument. |
| (4~20)mA/HART(Four wire system) | Separate power supply and the current signal, respectively using a two-core shielded cable. The supply voltage range see technical data. |
| RS485 / Modbus | Power supply and Modbus signal line are separated, respectively using a two-core shielded cable, the power supply voltage range see technical data. |
