Full CE approval
Options:
Temperature compensation via external sensor
OEM Application Software through Bootloader,
allowing special functions to be programmed via RS485
RS232 - RS485 Converter
Alternative sensitivities (1 - 20 mV/V)
Precision vs Speed of Reading:
Generally, the higher the precision required from an analogue-to-digital system, the slower the speed of conversion to digital format. The DSC allows you to select the resolution and speed of reading that you require according to the Table below:
