DS4-NH3-100 Three-electrode Electrochemical Gas Sensor For Chemical Industry

DS4-NH3-100 Three-electrode Electrochemical Gas Sensor

Detection Principle:

Based on printed solid polymer electrochemical sensing technology with a three-electrode design. The sensor utilizes three electrodes made of noble metals, interacting with target gases through a porous membrane. When gas diffuses into the sensor, oxidation or reduction reactions occur, triggering an electrochemical reaction that generates a current proportional to the gas concentration.

Features:

1. Wide Voltage Range: Operates at 3.3V–12V DC (recommended 5V DC).
2. Broad Temperature Range: Functions at -40°C to +55°C without temperature compensation.
3. Superior Performance: Excellent linearity and fast response for real-time monitoring; long-term zero-point stability with anti-poisoning design for extended service life.
4. Easy Integration: Compact standard 4-series industrial size (20×16.6mm cylindrical) for seamless integration into new or existing products.
5. Low Power Consumption: Customizable sleep/wake function suitable for IoT and battery-powered applications; no preheating required, operational immediately after power-up.
6. Convenient Output: Supports simple UART digital output (3.3V half-duplex single-wire mode) for easy data collection and integration with microcontrollers or IoT systems.
7. High Precision: Professionally gas-calibrated at the factory, with calibration data stored in the sensor microprocessor for plug-and-play use. Diffusion-based calibration simulates real-world conditions to enhance accuracy.
8. Intelligent Safety: Self-identifies gas type and detection range; user-definable encryption codes ensure device compatibility and prevent errors; hot-swappable design, offline calibration protocols, and factory reset reduce maintenance downtime and avoid direct exposure to hazardous gases during servicing.

Performance Parameters:

1. Measurement Range: Multiple specifications available: 0–100ppm, 0–300ppm, 0–500ppm, 0–1000ppm, and 0–10000ppm.
2. Resolution: Up to 0.5ppm or lower (varies by model).
3. Accuracy: Typically high precision (specific values refer to product specifications).
4. Response Time: T90 <90 seconds (some models <40 seconds).

Electrical Parameters:

1. Output Type: UART digital signal output (3.3V half-duplex single-wire mode).
2. Operating Voltage: 3.3–12V DC (recommended 5V DC).

Physical Parameters:

1. Dimensions: 20mm (diameter) × 16.6mm (height).
2. Weight: Lightweight (inferred from dimensions, specific value not specified).

Environmental Parameters:

1. Operating Temperature: -40°C to +55°C.
2. Operating Humidity: Within common environmental humidity ranges (details refer to product manual).

Application Fields:

1. Chemical Industry: Monitors ammonia leakage and controls concentration in chemical production to ensure safety and environmental quality.
2. Animal Husbandry: Measures ammonia concentration in farms to support animal health and environmental optimization, reducing harm to animals and staff.
3. Environmental Protection: Monitors atmospheric ammonia for environmental quality assessment and pollution control.
4. Other Fields: Applicable to sites where ammonia may be generated, such as refrigeration systems and wastewater treatment plants, for real-time concentration monitoring to prevent leaks and ensure safety.
