Product Description Product Name: XK3190-EX-A18 Intrinsically Safe Weighing Indicator XK3190-EX-A18 is a high-performance, intrinsically safe weighing indicator designed explicitly for hazardous environments where explosive gases or dust may be present. Engineered with robust safety features and reliable weighing technology, it ensures accurate and stable measurement while prioritizing operational safety. This instrument is an ideal solution for industries such as chemical processing, petroleum, pharmaceuticals, mining, and grain handling.Key Features· Explosion-Proof Certification: Certified as Intrinsically Safe (Ex ib IIC T4 Gb / Ex ib IIIC T135°C Db). It can be safely used in Zone 1, Zone 2, Zone 21, and Zone 22 hazardous areas, preventing the ignition of explosive atmospheres.· High Immunity to Interference: Advanced circuit design and shielding provide excellent resistance to electromagnetic and radio frequency interference, ensuring stable readings in electrically noisy industrial environments.· Versatile Application Support: Compatible with a wide range of analog and digital load cells. Supports various weighing applications including hopper scales, platform scales, tank weighing, and batching systems.· User-Friendly Interface: Features a bright, high-contrast LCD display with clear digit readout and an intuitive keypad for easy operation and configuration, even while wearing gloves.· Robust Construction: Housed in a durable, sealed enclosure (typically IP65 rating or higher) that protects against dust and water ingress, suitable for harsh industrial conditions.· Comprehensive I/O Options: Equipped with standard input/output interfaces such as RS232 and RS485 for seamless connectivity to printers, computers, PLCs, or other control systems.· Power Flexibility: Can be powered by an internal rechargeable battery pack for portable applications or via a certified external safe-area power supply/barrier for fixed installations.Parameter SpecificationModel XK3190-EX-A18Safety Certification Ex ib IIC T4 Gb / Ex ib IIIC T135°C DbApplicable Zones Zone 1, Zone 2, Zone 21, Zone 22Display High-contrast LCD with LED backlightA/D Resolution ≥ 1,000,000 countsSampling Speed Typically 10-80 times per second (adjustable)Input Sensitivity ≥ 0.3μV/dLoad Cell Excitation 5V DCMax.
