AutomationDirect's acuAMP line of current
sensors now includes ac ground fault sensors and dc current transducers and
The GFS series of ground fault sensors monitors all
current-carrying conductors in grounded single and three-phase delta or wye
systems. Available in fixed-core models, the GFS series features jumper-selectable
setpoints of 5, 10 or 30 mA. The sensors can accommodate up to 14 AWG copper
wire and feature mechanical relay outputs with either manual or auto reset. The
UL and CE approved GFS series of ground fault sensors start at $136.
The DCT series of dc current transducers combines a Hall Effect sensor and
signal conditioner into a single package for use in dc current applications up
to 400A. Designed to be compatible with most PLCs, data loggers and SCADA
systems, the DCT series features jumper-selectable current input ranges and
4-20 mA or +/- 10V dc outputs. Available in split-core or fixed-core models, DCT
current transducer prices start at $117.
DCS100 series dc current switches have jumper-selectable current input
ranges up to 100A and are available in normally-open solid-state and SPDT relay
output models. The switches are equipped with removable terminal blocks which
accept up to 12 AWG solid or stranded wire. Prices for DCS100 dc current switches
start at $90.
All acuAMP sensors are panel-mountable; DIN rail adaptor accessories are also
With a better understanding of materials’ response to load and temperature, researchers could potentially use the knowledge to improve design. The research could even help geologists studying plate tectonics.
