Product Description
Smart Fixed 4G Wireless Combustible Gas Detector
The HNAG1000-EX online fixed gas concentration detector is engineered for the real-time, highly accurate detection of combustible gas (EX / LEL) concentrations and leakages. Utilizing an imported catalytic combustion sensor and advanced microcontroller technology, this analyzer delivers rapid response times (T90 < 10S) and exceptional measurement precision (±2% F.S).
Rugged Aluminum Alloy & Explosion-Proof Design
Constructed with a heavy-duty aluminum alloy metal casing, this fixed detector is built to withstand extreme industrial environments. It features an intrinsically safe circuit design with an Ex d IIC T6 and ATEX explosion-proof rating, as well as IP66 protection against splashing water and short periods of rain. To maintain optimal sensor performance, the device is equipped with a dustproof filter chip that effectively blocks industrial dust.
Seamless 4G & LoRa Wireless Transmission
Breaking the limitations of traditional hardwiring, this intelligent gas monitor integrates a dedicated data card module to support comprehensive wireless transmission. By utilizing custom 4G upload technology, real-time gas concentration data is transmitted 24/7 directly to mobile applications and web dashboard monitoring systems. This enables facility managers to track real-time accurate data, receive instant alarm information, and sync across multiple devices from anywhere.
Additionally, the device supports LoRa P2P and Bluetooth Tx communication. The LoRa transmission flow allows the detector to communicate seamlessly with LoRa signal receivers and gas alarm controllers over long distances without reliance on cellular networks.
Internal Architecture & Multi-Signal Output
The internal structure of the detector is highly modular and functionally rich. The main circuit board houses dedicated slots for the 4G module and LoRa connections, along with dual sensor interfaces supporting plug-and-play maintenance. For traditional control systems, the device simultaneously outputs standard RS485 (MODBUS RTU) and 4-20mA signals, and features a built-in relay switching output (220VAC 3A / 24VDC 3A) to directly drive exhaust fans or solenoid valves.
User Interface & Remote Commissioning
The detector features a high-definition LCD screen that displays real-time gas concentration, measurement range, and system status (Run, Fault, Low Alarm, High Alarm). During gas leaks, the dual sound and light alarm instantly alerts on-site personnel.
To ensure safety in highly explosive zones, the device supports remote commissioning. Operators can utilize the included infrared remote control to configure settings, calibrate the sensor, and silence alarms without ever needing to open the explosion-proof cover.
Frequently Asked Questions (FAQ)
Q: What is the housing material of this detector?
A: The HNAG1000-EX is encased in a robust aluminum alloy metal casing, providing excellent mechanical strength and an Ex d IIC T6 / ATEX explosion-proof rating for hazardous locations.
Q: How does the 4G wireless transmission work?
A: The detector contains an internal module slot for a 4G data card. Once connected, it transmits real-time continuous gas concentration data and alarm events directly to a mobile app and web monitoring dashboard for 24/7 remote oversight.
Q: Does it have local alarms in addition to mobile notifications?
A: Yes. The device is equipped with an integrated dual sound and light alarm that flashes red and emits a loud siren locally, while simultaneously sending push notifications via the 4G network.
Q: How do I calibrate the device without opening the enclosure?
A: The detector comes with an infrared remote control. This allows you to perform remote commissioning, zero tracking, and multi-level calibration from a safe distance without opening the cover in dangerous situations.
