RKI Instruments, GD-K71D, Sample Drawing Sensor Transmitter

From RKI Instruments,

The GD-K71D, a complete sample drawing gas monitor, with digital readout and alarm relays. A new gas sensor technology utilizing an intelligent sensor for remote location calibration and setup is used. GD-K71D sensors are designed to provide longer time periods between calibrations. Calibration intervals cab be extended to12 months of on-line service which equate to reduced maintenance costs. In addition, the sensors can be calibrated away from the gas detector installation, for example in a service area or off site, eliminating the inconvenience of having calibration gases in the fab or monitoring location. The GD-K71D easily connects to existing PLC systems 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.

Features Include:

• LED digital display
• Sensor information and calibration is stored within sensor memory
• Several data transmission options available
• Zero suppression and correction
• Housing design for narrow wall mounting locations
• Self-diagnostic functions by microprocessor
• Electrochemical sensors for most semiconductor gases
• Built-in sampling pump
• Easy replacement of pump and sensor
• Two alarm levels with relays, plus trouble alarm
• 24VDC operation
• Optional NEMA 4X housing available

Applications Include:

• Semiconductor
• Chemical Processing
• Laboratory
• Manufacturing
