Product Description

GM8802F-4 Field mounting transmitter

The field transmitters are an innovative value-adding solution for batching and weight monitoring applications where many channels of A/D are needed.

The instrument has 4 channels of independent A/D bundled flawlessly in a IP65 case,allowing it to perform under the worst industrial environments and dramatically reducing the amount of shielded analogue line needed and creating significant savings on the project’s bottom-line.
