STRAIN-GAUGE EMBEDDED DIGITAL CONVERTERS
These digital converters convert the signal from a Wheatstone bridge (mV/V) into a standardised digital signal RS-232, RS-485 or USB
o Very high resolution
o Linearisation of transducer signal available
o High transmission speed
o Internal or external mounting depending on the size of the transducer
o When external, rectangular box in aluminium (protection class IP65)
