Analog Entries:
The types of entry signals accepted by AirGate-GPRS and their minimum measurement bands are selected in the
Configuration software and are listed in the following table.
TYPE OF INPUT MEASUREMENT RANGE EXACTNESS
Linear 4 to 20 mA Configurable ± 1.0 % (F.E.) *
Linear 0 to 10 V Configurable ± 1.0 % (F.E.) *
F.E. = Scale Background = Span
(*) Note: he background scale is in regards to the input of the sensor’s signal and not the configured recommended range.
