Gas Detection Transmitters use variety of sensing elements.September 25, 2009 -
Offering array of sensing technologies including hydrogen-specific ppm and LEL versions, GD-70D Series includes LCD display, tri-color bar graph for visual notification of alarm status, programmable low/high alarm relays, and fault relay. Sample-draw transmitters retain all calibration and sensor-specific data in non-volatile memory, allowing sensors to be hot-swapped in field with no programming required. Firmware automatically corrects for long-term zero and span drift.

Multifunctional Sensor Unit - New Intelligent Sensor
The new Model GD-70D series 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 ppm and 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 sensor 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 the field location. The GD-70D firmware automatically corrects for long-term 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 large, easy to read integral LCD display, tri-color bar graph for visual notification of alarm status, programmable low and high alarm relays, and fault relay. Pump flow is self-tuning for maintenance-free 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.
