The aftertreatment SCR intermediate NH3 (ammonia) sensor is a smart device that communicates with the engine control module via the J1939 data link. ... The aftertreatment intermediate NH3 sensor is used to measure the ammonia in the aftertreatment system.Mar 14, 2019
How do you test for NH3?
The ammonia test measures the level of ammonia in a blood sample. Blood is drawn from a vein (venipuncture), usually from the inside of the elbow or the back of the hand. A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe.
How does the gas sensor work?
It works by monitoring different gas levels in the air. These devices are generally battery operated and used for safety. Once they detect a higher than normal concentration of gas in the air, they warn people in the location through a series of really hard to miss audible beeps.Jul 26, 2018
How does NH3 sensor work?
Ammonia detector works on electrochemical principle. ... Voltage, electrolyte and electrode material are selected to suit the gas being monitored so that it is transformed electrochemically on the measuring electrode and a current flows through the sensor. This current is proportional to the gas concentration.
What are ammonia sensors?
The most effective way to prevent issues is by installing ammonia leak detectors in manufacturing and storage areas. These ammonia gas monitor devices provide continuous readings of NH3 gas concentrations and trigger an alarm or signal when levels become too high.
Which chemical is used for the detection of NH3?
How is ammonia leakage detected?
In the case of ammonia, small leaks can be detected by the rapid drop of temperature due to the evap- oration of the released liquid ammonia. These local thermal anomalies can be reliably detected by a fiber optic distributed temperature sensing system that is able to detect temperature changes.
Is there an ammonia detector?
Industrial Scientific's personal single-gas detector GasBadge® Pro, or multi-gas detectors, including the Ventis® Pro, and the MX6 iBrid®, as well as the Radius® BZ1 Area Monitor reliably detect low ppm ammonia within the specified range.
