Description

The DSC is a load cell digitiser that takes a strain gauge input and converts it to an RS232 or RS485 digital signal.  The strain gauge converter is designed for use with a variety of transducers including load cells, pressure transducers, torque sensors and displacement transducers.

The DSC strain gauge load cell digitiser offers high accuracy, high-speed signal conversion with digital linearisation and temperature compensation to improve transducer far beyond its normal performance level.  Available protocols are; ASCII, MODBUS and MantraCAN (J1939).

Designed to be mounted in-line with the transducer, the load cell converter is available pre-mounted in an IP65 enclosure.  There are two enclosure options; the DSJ1 which holds a single load cell converter, and the DSJ4 which holds four load cell converters.  The DSJ4 requires RS485 output versions of the load cell converter as this is the only type suitable for ‘daisy-chaining’ on a single bus.

The PC-based calibration of the strain gauge converter can be performed directly from the sensor output signal, or as an mV/V sensitivity entry for ultimate flexibility.

Other strain gauge converter features include very high resolution of up to 1:200,000, high speed output at up to 500 updates/second and programmable dynamic filtering.
