Gas Monitoring: the GD-K77D Smart Sensor / TransmitterA top of the range detector head with internal sample draw pumpThe GD-K77D Gas Monitoring detector head 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-K77D sensors are designed to provide a longer time period between calibrations. Calibration intervals have been cut in half 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 offsite. This eliminates the inconvenience of having calibration gases in the fab or monitoring location. GD-K77D easily connects to an existing PLC system and is ideal for applications needing a local readout or where a relay control is needed. Features include: Digital display with LCD back light / Sensor information and calibration is stored within sensor memory / Several data transmission options available / Zero suppression and correction / Smaller 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, plus trouble alarm with relays / 24VDC operation / Optional NEMA 4X housing available
The GD-K77D is ideal for the following applications: Semiconductor / Chemical Processing / Laboratory / Manufacturing Learn more about our GD-K77D Gas Monitoring System and our range of other Fixed Gas Detectors
