Technical Characteristics of Gas
1. Non-Interference Encapsulation: The detector is encapsulated within a explosion-proof metal housing, equipped with a glass-covered lid. The magnetic programming button on the transmitter panel can be operated using a handheld magnetic programming tool, ensuring uninterrupted operation of the sensor interface. Calibration and on-site debugging can be performed without opening the lid, maintaining the original condition of the site.
2. Simple Calibration: Calibration prompts are displayed on the backlit LCD screen, greatly simplifying the calibration process. Technicians can easily start the calibration program using a magnetic programming tool. Once the calibration program is initiated, the detector displays the calibration menu, offering two options: Zero Calibration and Span Calibration. Choosing ZERO initiates the automatic zeroing function. After calibration is complete, the display will return to the calibration menu. Selecting SPAN starts the automatic span calibration, and the screen will prompt for the gas type and its concentration that the detector is calibrated for. Once the gas is provided, the detector begins the automatic span calibration. After the signal stabilizes, the detector will record the starting data and prompt the operator to disconnect the gas source. Once the gas concentration is zeroed, the detector will automatically continue with its normal operation. If for any reason the detector cannot perform the calibration program, it will display an error message. This program takes no time and is almost error-free.
3. Signal Output: The infrared gas sensor has two types of signal outputs: analog 4-20mA output and RS-485 data bus output. The latter only has a 4-20mA output. The output signal is a 4-20mA linear analog signal related to the detection range. This signal is compatible with the 10 series and 12 series multi-module controllers, programmable logic controllers, and other standard data acquisition devices. The analog output also has two other functions. When entering the calibration menu, the 4-20mA signal drops to 2mA. This low current will remain until the sensor returns to normal operation. In case of an error, the 4-20mA signal drops to 0mA, and this condition will persist until the error state is resolved. Changes in these output signals can be used by external devices to identify and record the sensor's operating status.
