3. Product Advantages
-
Non-Intrusive Operation: Fully configurable via magnetic switches on the front panel. You don’t need to open the enclosure to calibrate or change settings, which is vital in “hot” (explosive) environments.
-
Visual Status Clarity: The tri-color backlit display allows workers to identify the safety status from a distance at a glance.
-
Plug-and-Play Sensors: The transmitter automatically recognizes the sensor cartridge plugged into it and configures the software accordingly.
-
Robust Durability: With an IP66 rating and explosion-proof certification, it is built for the harshest industrial conditions, including offshore platforms and chemical plants.
-
Common Platform: Uses a standardized transmitter for various sensors, reducing the need for extensive spare parts inventory and training.
4. Key Considerations (Precautions)
-
Sensor Selection: The SPXCDULNTXF is the transmitter only. You must purchase the appropriate Flammable (Catalytic) or IR sensor cartridge separately.
-
Conduit Sealing: For UL/c-UL installations, ensure the 3/4″ NPT entries are sealed with appropriate explosion-proof conduit seals (poured seals) within 18 inches of the device.
-
Calibration: While it is a “smart” device, regular bump tests and annual calibrations are required to ensure the accuracy of the electrochemical or catalytic sensors.
-
Mounting: Ensure the sensor points downward to prevent water or dust accumulation on the sensor face.
5. Applications
The Sensepoint XCD is widely used in both indoor and outdoor hazardous areas:
-
Oil & Gas: Refineries, onshore/offshore drilling platforms, and production facilities.
-
Power Plants: Monitoring for hydrogen or fuel leaks.
-
Wastewater Treatment: Detecting methane levels in digester areas.
-
Manufacturing: Chemical processing, painting booths, and solvent storage.
-
Food & Beverage: Refrigeration systems and processing lines.
