The new Model GD-70D smart gas detection transmitter series sets a new
standard for performance, flexibility, and versatility. The GD-70D sample-draw
transmitter offers an array of sensor technologies unmatched in the industry,
including unique offerings, such as our hydrogen-specific or LEL versions.
The long life high capacity pump and wide variety of sensing elements are
replaceable in a few seconds, with no tools required! The smart sensors retain
all calibration and sensor-specific data in non-volatile memory, so sensors
can be hot-swapped in the field with no programming required. The sensors
also retain calibration information, which means they can be conveniently
calibrated separate from the transmitter, avoiding transport of calibration
gases to field locations. The GD-70D firmware automatically corrects for longterm
zero and span “drift” minimizing maintenance and maximizing reliability.
The GD-70D can be used as a stand-alone device, offering a number of
communication protocols to existing PLC systems, or can be integrated with
RKI’s Beacon series of single and multi-channel controllers.
All GD-70D transmitters include a large, easy to read integral LCD display, tricolor
bar graph for visual notification of alarm status, programmable low and
high alarm relays, and fault relay. Pump flow is self-tuning for maintenancefree
operation. Because all GD-70D base units are identical, sensors can be
interchanged with no programming or tools required, resulting in maximum
flexibility to the user. NEMA 4X 115 VAC versions available.
