Product Description
1. Ultra-Compact Industrial Design for Flexible Integration
With an external dimension of just diameter 48mm × height 95mm (excluding pins) and a standard M20 * 1.5 external thread for mounting, this module is exceptionally compact and lightweight. This makes it perfectly suited for integration into space-constrained designs, such as portable H2S detector units and handheld gas leak detector tools, without compromising on robustness due to its ABS/aluminum alloy housing.
2. Multi-Principle, High-Performance Sensing Platform
The module supports a selectable ("Optional") measurement gas and detection principle. It is designed to professionally integrate high-quality sensors, including electrochemical (ideal for H2S gas), catalytic combustion, infrared, thermal conductivity, and PID types. This flexibility allows it to serve as the sensing core for a precise hydrogen sulfide monitor or other specific gas sensor detector applications.
3. High Accuracy, Rapid Response, and Long-Term Stability
Engineered for dependable performance, the module guarantees a sampling accuracy of ±3% F.S. and repeatability of ±1% F.S. It delivers a fast response time (T90) of <30 seconds with a short 10-second preheat time, ensuring quick and reliable threat detection. Its exceptional long-term drift of ≤±1% F.S. per year ensures stable readings over its 2~3 year service life, which is critical for maintaining the reliability of any H2S alarm system.
4. Intelligent Features for Simplified Operation & Maintenance
The module simplifies setup and upkeep. It features factory-precise calibration for true plug-and-play operation and includes a data recovery function to safeguard against operational errors. Users can perform zero-point fine-tuning and connect directly to a computer for self-calibration, facilitating easy maintenance. Its output interface combines RS-485 digital communication with a selectable 4~20mA analog current, providing maximum flexibility for system debugging and integration.
5. Low-Power, Rugged Construction for Demanding Applications
Consuming a low operating current of ≤50mA from a 12-24V DC source, it is highly suitable for portable, battery-powered devices like portable H2S detector units. It operates reliably in harsh conditions, within a temperature range of -20°C to 50°C and humidity of 0-95% RH (non-condensing), making it an excellent choice for environmental monitoring, drone-based atmospheric sampling, and fixed industrial hydrogen sulfide detection systems.
FAQ:
1. Q: Can this module be used as the core sensor for a portable H2S gas detector?
A: Absolutely. Its compact size (Φ48mm x 95mm), low power consumption (≤50mA), and robust construction make it an ideal, high-performance sensing core for building reliable and durable portable H2S detector tools.
2. Q: What level of accuracy can I expect for hydrogen sulfide monitoring with this module?
A: When configured with an electrochemical sensor for H2S gas, the module delivers highly accurate and stable readings, with a sampling accuracy of ±3% F.S. and minimal long-term drift (≤±1% F.S./year), ensuring your hydrogen sulfide gas detector provides trustworthy data over time.
3. Q: How does the output configuration aid in building a complete gas detector system?
A: The dual RS-485 + 4~20mA output interface offers maximum integration flexibility. The 4~20mA signal can connect directly to PLCs or controllers, while the RS-485 allows for networked communication with multiple sensors, simplifying the design of complex gas detector systems.
