Some causes of differences in the NH3 concentration measured with the semiconductor sensors by one manufacturer

Popis výsledku v původním jazyce

The paper deals with continuous monitoring of NH3 desorption from material used as bedding in animal breeding establishments, using five semiconductor sensors SP-53 (FIS Inc.). In lab experiments, two groups of sensors from two categories, to which the manufacturer divided the sensors based on the value of their resistance RS, were used. Also the influence of air humidity over the values of NH3 concentrations measured by individual sensors was monitored. The study ascertained statistically relevant differences between NH3 concentration values measured by both groups of sensors, in the range from 8.5% to 23.1%. The biggest differences were confirmed for relative air humidity around 85%. It was verified that setting a convenient value of the load resistance RL with regard to the RS of each sensor, along with the selection of limited range of measured temperatures and relative air humidity, leads to satisfactory correction of the sensor output data, regardless of the division of sensors in categories pursuant to the value of their resistance in manufacturing.
