Smart Sensor/Transmitter with Readout
The GD-K71D is a complete sample drawing gas monitor, including digital readout and alarm relays. A new gas sensor technology using an intelligent sensor for remote location calibration and setup is used. The new GD-K71D sensors are designed to provide a longer time period between calibrations. Calibration intervals have been extended to12 months of on-line service which equates to reduced maintenance cost. In addition, the sensors can be calibrated away from the gas detector installation, for example in a service area or off site. This eliminates the inconvenience of having calibration gases in the fab or monitoring location. GD-K71D easily connects to an existing PLC system and is ideal for applications needing a local readout or where a relay control is needed. The automatic zero correction software provides excellent long term stability and minimizes false alarms due to zero drift.

RKI is proud to introduce and 
announce the release of our new product, the EAGLE 2. Building on the strong success of the popular EAGLE series.
The 2010 Winter Olympics Cauldron was built with a fixed gas detection system using RKI’s products. A Beacon 410 controller and four Direct Connect LEL sensors were installed inside the arms of the
outdoor cauldron.
RKI’s H2 sensors were also used inside the fuel cell buses that transported athletes and spectators, and in the garages and terminals where the buses were used
The GD-70D is a compact transmitter for detection of toxic gases, oxygen, or combustible gases and vapors. This new 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.
