REMOTE TOXIC, COMBUSTIBLE, AND OXYGEN GAS SENSORS FEATURES Extremely wide range of sensors Easy installation and maintenance Low cost of ownership Replacement of sensors are simple Rugged and reliable Several Xgard Types For All Applications Xgard Type 1: Intrinsically safe Toxic and Oxygen gas detector Xgard Type 2: Flameproof Toxic and Oxygen gas detector Xgard Type 3: Flameproof Flammable gas detector Xgard Type 4: Flameproof high temperature Flammable gas detector Xgard Type 5: Flameproof Flammable gas detector with 4-20mA output Xgard Type 6: Flameproof Thermal Conductivity type gas detector Xgard Type 7: Flameproof Sulphistor Hydrogen Sulfide gas detector Xsafe: Safe area Flammable gas detector XGARD The Xgard range of gas detectors have been specifically designed to meet your requirements. The dangers presented by toxic and flammable gases as well as oxygen deficiency vary with each application. Xgard offers four different sensor concepts so you can choose exactly what you need for your site. Xgard is available in flameproof, intrinsically safe or safe area formats for use in all environments no matter what the classification. Xgard can accommodate M20, M25, 1/2 NPT or 3/4 NPT cable glands for all site requirements and was designed for either wall or ceiling mounting without the need for additional brackets. Accessories are available for duct mounting, sampling applications, and remote gassing for simple sensor checking. Xgard is constructed from highly durable marine-grade aluminum with tough polyester coating designed to operate even in the harshest conditions. Spray deflectors and weatherproof caps are available for use in areas subject to regular wash-downs, or offshore environments. CEA Instruments, Inc. "EXPERTS IN TOXIC GAS DETECTION"
