2011-07-27· Delphi SCR ammonia (NH3) sensor technology Due for initial production in 2012, Delphi has developed an ammonia sensor for the automotive industry, which enables more efficient emissions control. The system allows the SCR (read also more here) to work at optimized NOX conversion rates, which in turn improves fuel efficiency.
Each sensor is located a fixed distance from the distributor, which allows the sensors to monitor the temperature when the anhydrous reacts to the pressure drop. This reaction can cause the temperature to vary greatly depending on the flow and pressure. If all the knives are getting the same flow, the temperature should be the same for every sensor. If the flow or pressure varies slightly this ...

The sensor triggers an alarm if there is an NH3 leak in the CO2 part. A leak results in several hours of cleaning the pipes and heat exchanger. If a CO2 leak occurs in the NH3 part, salt crystals are formed. These salt crystals are very corrosive and lead to clogging of the parts. If the leak is not stopped in time, it can lead to extensive damage to

NH3CAN uses a ceramic sensor that is mounted in the exhaust of the engine and communicates NH3 via its CAN port. Although designed as a measurement tool, the NH3CAN can be easily integrated into an engine or aftertreatment control strategy. The CAN node identification can be programmed by the user allowing multiple NH3 modules on the same bus.

2021-01-15· It can be seen that the CuPc/ZnO sensor exhibits the largest response to NH 3 compared with the other interferential gases under red light illumination at 27 °C. However, lower responses are observed for ZnO and CuPc/ZnO sensors to all reduce gases under the dark condition. It is suggested that the sensor based on as-prepared CuPc/ZnO shows an excellent selectivity to NH

4 NH3 RESPONDER Getting Started The NH3 Responder detector is especially configured for ammonia response operations. It utilizes two sensor technologies to cover the ranges of interest in an ammonia response operation. The first sensor is a PID sensor, which is configured to display ammonia concentration readings in the range of 0-1000 ppm.
Ammonia (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.
