The selection and use of flammable gas detectors

14 In many fixed gas detection systems, the sensor units are designed to use natural diffusion as the sampling method. The sensors are located at or near points where there is the possibility of a gas release. 15 However, natural diffusion as a sampling method can be slow. In many cases a faster response is needed, and the sample is transported to the sensor using a sampling pump. This is ...

Feed-height sensor - Lely

In each round the feed-height sensor identifies the quantity of feed at the feed fence. The feed robot determines whether fresh feed is necessary, and if so how much, without you having to think about it. The only thing that needs to be configured manually is the height of the feed at the feed fence. In addition to measuring the feed, the Vector also pushes it. Therefore, even if it does not need to be topped up, …

At What Height Should Sensors be Mounted?

The sensor mounting height depends the type of application and on the density of the gas relative to air. Heavier than air gases should typically be detected 6 inches from the floor, lighter than air gas sensors should typically be placed on or near the ceiling, and gases which have a density close to that of air should have sensors installed in the "breathing zone" 4 - 6 feet from the floor. The breathing zone …

· A gas sensor is a device which detects the presence or concentration of gases in the atmosphere. Based on the concentration of the gas the sensor produces a corresponding potential difference by changing the resistance of the material inside the sensor, which can be measured as output voltage. Based on this voltage value the type and concentration of the gas can be estimated. MQ-6 Gas Sensor ...
