Fixed Ammonia (NH3) Gas Detection
Ammonia gas is a colorless gas with an extremely strong and distinctive odor. When exposed to the air, it mixes with water or humidity and causes irritation or burning of the skin, eyes, nose, throat, and lungs. In high concentrations, the gas can also cause respiratory failure.
Ammonia gas detectors are an essential part of workplace safety and provide continuous monitoring of gas concentration in the air. Fixed gas detection utilizes electromechanical sensors that feature a liquid electrolyte. As ambient air passes through the sensor, electrodes within the electrolyte produce a current that digitizes the flow to produce a measured value that is transmitted as an analog signal. When levels reach a concentration higher than what is allowed per safety regulations, the ammonia gas sensor triggers a warning signal or alarm.

Proper Ammonia Gas Sensor Placement for Effective Gas Detection
Proper placement of the ammonia gas sensor is important for it to be effective. Since ammonia gas is lighter than air, it will typically rise to the ceiling when it is released. Placing ammonia gas sensors at ceiling height will help ensure that leaks are detected before they reach dangerous levels. If they are placed too low in the room, the ammonia gas sensors will take much longer to detect the gas, allowing it to accumulate and cause respiratory irritation.
When installing ammonia gas sensors for fixed gas detection, it is important to avoid placing the detectors near windows, vents, or fans. Installation near drafts or circulating air will prevent the sensor from getting an accurate reading, making the device less effective. Humidity and temperature are also important, as hot or humid conditions can affect the accuracy of readings. If your operating environment is humid or the ammonia gas sensor will be exposed to high temperatures, the use of protective heat shields may be required.
For effective ammonia gas detection, you also need to have enough sensors to provide enough coverage for your room size. Our experts can help you determine how many ammonia gas sensors you need based on your facility size, ammonia equipment size, and type of sensor selected.
The Importance of Maintaining Your Sensors for Effective Ammonia Gas Detection
Ammonia gas sensors should be tested monthly, at a minimum, to ensure they are functioning properly. These tests, known as bump tests, involve briefly exposing the sensor to ammonia gas to see if it responds. If the ammonia gas sensor does not trigger an alarm after exposure, the device will need to be calibrated. To calibrate the anomia gas sensor, the device is subjected to prolonged exposure to ammonia gas. During this time, the readings provided by the sensor are monitored to ensure accuracy.
The date the testing took place, as well as the results, should be recorded as part of your fixed gas detection preventative maintenance plan. Maintenance and calibration can be performed by a facility manager, or by a local RC Systems gas detection expert. Contact our support team to learn more.

Fixed Gas Detection for Ammonia (NH3) Used in RefrigerationAmmonia (NH3) is the most common choice of refrigerant for many industries including food and beverage, HVAC, schools, laboratories, hospitals, and many others. Because of this, ammonia detection is more important than ever. Anhydrous ammonia can cause an immediate danger to life and health at only 300 ppm, and is explosive in certain conditions.
Utilizing our SenSmart Gas Detectors and ViewSmart Alarm Controllers we can provide complete ammonia gas detection and alarm control solutions. Installing sensors in colde environments, such as those you find with ammonia refrigeration, is no issue for RC Systems' ammonia (NH3) sensors, as they have heated sensor elements helping to lower their operating temperature range to -40C. RC Systems has a professional engineering team ready to provide solutions for ammonia gas detector system engineering, from system design with detailed wiring diagrams, to site startup and commissioning services.
