The GT-2500-FLP, a PESO certified Flameproof Smart Gas Detector/Transmitter, stands as a robust solution for the swift and dependable detection of Oxygen, Toxic, Combustible, and Volatile Organic Compounds (VOC) gas leaks. Its user-friendly design includes a 7-Segment LED display for digital gas concentration readouts and 8 LEDs providing clear indications of the instrument’s status. With a standard 4-20mA signal output and three relay outputs, each with a 5A rating for both AC and DC, it ensures seamless integration into monitoring systems. The optional Isolated RS-485 Communication Port with MODBUS RTU PROTOCOL enhances connectivity. The device boasts a hot-swappable gas sensor module, allowing for easy maintenance and servicing, and features non-intrusive programming for the Flameproof Model using a Magnetic Wand. Recognizing its versatility, it can detect gas concentrations down to PPM, %V/V, %LEL, and mg/m³, with indications for various conditions such as ‘Sensor Open,’ ‘Over Range,’ ‘Sensor Replace,’ ‘Cal Due,’ ‘Cal Fail,’ and ‘mA Loop Open.’ This comprehensive set of features positions the GT-2500-FLP as a reliable and efficient gas detection solution for diverse industrial applications.
