Product Overview The Gas Sensor Unit Transmitter (NGB-3A series) is a 4-20mA current output module developed for our electrochemical gas sensors (CO, H₂S, NH₃). It can be easily incorporated into equipment because it provides an output proportional to the gas concentration. By using this module, connection is easy and the development man-hours for gas detection systems can be significantly reduced. Recommended for the following needs: Want to incorporate a gas sensor into equipment Want to collect data with 4-20mA standard output Looking for a small, lightweight module When voltage output (1-5V) is required (optional) Product features ✅ 4-20mA output proportional to gas concentration ✅ Compact design (40mm x 28mm, approx. 6g) ✅ Optimized for our electrochemical sensors (CO/H₂S/NH₃) ✅ Equipped with zero and span adjustment functions ✅ Compatible with DC12V to 24V power supply ✅ Maximum load resistance of 700Ω ✅ Optional 1-5V voltage output also available ✅ Straight/right angle/connector type pin selectable Usage examples ⚡ Incorporation into environmental monitoring equipment ⚡ Safety monitoring in factories and research facilities ⚡ Portable gas detector development Specifications list Item Specifications Compatible sensors Our electrochemical sensors (CO, H₂S, NH₃) Output 4-20mA (option: 1-5V voltage output) Power supply voltage: DC12V to 24V Maximum load resistance: 700Ω (at DC24V) Board size: Approx. 40mm x 28mm Board weight: Approx. 6g Operating temperature range: 0 to 40°C Product variations Model Pin specifications Features NGB-3APS Straight pin header Standard configuration NGB-3APR Right angle pin header For devices with height restrictions NGB-3ACS Straight connector Cable Easy to connect configuration Notes ● Adjust the output zero and span carefully. ● Use the power supply voltage and load resistance within the specified range. ● We recommend storing the sensor for a maximum of 6 months. ● Avoid condensation and water immersion during storage and installation.

[Notice] Sales of this product have been temporarily suspended. We are currently verifying the stability of product performance, and the re-release date is undetermined. We will announce this page or a notice as soon as a replacement product is available. We apologize for any inconvenience this may cause and appreciate your understanding. Product Description: The fixed ammonia alarm (NDS-9A-NH3) detects and displays ammonia (NH₃) concentrations in the air in real time, and reliably sounds an alarm via a buzzer and LED when a dangerous concentration is reached. The measurement range is 0 to 100 ppm, with alarm settings of 20 ppm and 50 ppm, helping to ensure workplace safety. Alarm history and concentration fluctuations are automatically recorded as logs and can be saved in CSV format using a USB memory stick. Furthermore, the relay contact output allows for connection to external devices, making it suitable for integration into factory and facility safety systems. 🔷 Applications: Refrigerant ammonia leak monitoring; Ammonia concentration management in chemical factories and fertilizer manufacturing plants; Safety management of ammonia emissions in livestock facilities (livestock barns, chicken coops, etc.); Ammonia gas monitoring in sewage and wastewater treatment plants
