Capteur d'ammoniac

Our extensive offer of sensors for use in industrial automation also includes ammonia sensors.  

Ammonia Sensor DOL 53 consists of an electrochemical diffusion sensor and signal processing electronics. This sensor is intended for stationary, continuous monitoring of the ammonia concentration in the air. It provides information about ammonia concentration measured by the sensor (in a given place). The measurement is made in a ppm unit, concerning the concentration in volume. Ammonia Sensor DOL 53 is connected to a suitable control unit over a 3-wire cable. 

Ammonia sensor - applications:

• stationary, continuous monitoring of the ammonia concentration in the air with conditions typical for inventory buildings.
• vehicles - control in a closed cycle of SCR (Selective Catalytic Reduction) systems used in vehicles with Diesel engines.
• as a cooling factor in industrial cooling.
• in icehouses; cooled storages; sorting offices.
• machine workshops;
• technological objects;
• ammonia storage surroundings or of other cooling factors. 

Ammonia is a dangerous gas, with a characteristic smell, combustive and explosive of mixed with air. With low concentrations it is not that hazardous for humans, however, with concentrations of 400 ppm or above it's highly dangerous. 

Ammonia sensors are a key part of detection systems in ice houses and machine rooms with ammonia systems - provide safety for workers, products, objects, systems, and the environment. The choice of the right sensor depends on previously listed usages and the reasons why we need to install such devices. It also depends on fire requirements, possible errors, and the level of gas we want to be able to detect. The place in which we'll install the sensor is as important. They should be located at the highest points because ammonia is lighter than air. It's also crucial to consider the risk of freezing the sensor in icehouses because it can disrupt its proper operation.
