The EC2232bX series carbon monoxide gas alarm is a field-display type detection instrument designed for real-time monitoring of hazardous gas levels. It features an integrated functional module design, consisting of two main components: the base module and the sensor module. The standard digital interface ensures secure and error-free connection between modules, making hot-swapping and on-site replacement quick and efficient.
This device supports various communication and output options. The A-BUS module enables bus communication, while the 4~20mA module provides analog output. The switch module offers relay outputs for alarms and fault signals, and the wireless module allows remote communication with a host system. Additionally, the RS485 module supports MODBUS signal transmission, offering flexible integration into existing systems.
The independent sensor module handles all sensor parameter storage and signal conditioning, enabling seamless replacement and combination with other modules without the need for recalibration or reconfiguration. This feature not only extends the product's lifespan but also simplifies off-site calibration and maintenance, eliminating the hassle of disassembling the entire unit and reducing long-term maintenance costs.
By combining different modules and sensor types, users can customize detectors to meet specific application requirements. The device includes a high-contrast LED display for real-time gas concentration readings, with adjustable low and high alarm thresholds. It supports key-based calibration, allowing users to set calibration values based on any reference gas concentration. Field calibration can also be performed using infrared or magnetic rod methods, without requiring access to the internal components, ensuring ease of use and safety.
The AEC2323 explosion-proof sound and light alarm is suitable for use in hazardous areas classified as Zone 1, Zone 2, and for gases in IIA, IIB, IIC groups, with temperature classes T1 through T6. It is also equipped with a unique noise reduction control function that allows it to be silenced remotely via a controller or calibration device, while maintaining visual alarms for continued safety awareness.
The carbon monoxide gas alarm is known for its flexibility, fast replacement, stable performance, good consistency, high sensitivity, low power consumption, and multiple output options. It is widely used in industries such as petroleum, chemical, steel, and specialized industrial plants where flammable or toxic gases may be present.
Key Features:
- **Highly Integrated Design**: The sensor module combines sensors and processing circuits, performing full data calculation and signal conversion independently. It includes a built-in heating function to enhance low-temperature performance.
- **High-Concentration Protection**: Automatically cuts off power when gas levels exceed safe limits and resumes detection every 30 seconds until normal levels are restored.
- **Standard Digital Interfaces**: Gold-plated connectors ensure reliable and hot-swappable connections in the field.
- **Flexible Configuration**: Multiple sensor modules can be combined to create customized detectors with specific functions and detection ranges.
- **Easy Sensor Replacement**: Sensors for different gases and ranges can be replaced quickly without recalibration. The detector automatically reads factory-calibrated data upon replacement.
- **Clear Field Display**: High-brightness LED display offers excellent visibility in industrial environments. Calibration can be done via keys, infrared remote, or magnetic stick, providing convenient and flexible operation.
