A particular kind of chemical sensor called a Pellistor bead is employed to look for flammable gases in the surroundings.
It comprises of a tiny ceramic bead covered in a platinum- or palladium-based catalytic substance. The catalyst substance on the bead reacts with the combustible gas when it is exposed to it, changing the bead’s electrical resistance.
The concentration of the combustible gas in the surroundings can be calculated from the change in resistance. In industrial environments where the presence of combustible gases presents a safety issue, pellistor bead sensors are frequently utilised in gas detectors and monitors.
The great sensitivity and short response times of Pellistor bead sensors to combustible gases are one of their advantages. Yet, if exposed to specific chemicals or environmental variables, they may be susceptible to false alarms and less effective at detecting other types of gases.
Global pellister bead chemical sensor market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Their sensor is perfect for a variety of applications where dependability and precision are crucial because it is also made to be small, simple to install, and easy to maintain. Using our Pellister bead chemical sensor, we are convinced that we can offer our customers reliable and accurate chemical detection solutions.
Their Pellister bead chemical sensor is very adaptable and may be used to detect a wide range of chemicals, including volatile organic compounds, carbon monoxide, nitrogen oxides, and sulphur dioxide.
It can be utilised in industrial settings, for environmental monitoring, for indoor and outdoor air quality monitoring, and for other purposes.
The Pellister bead sensor operates on the idea of catalytic combustion, in which the target chemical is oxidised on the surface of a metal bead with a specific coating. A thermistor measures the heat produced by the oxidation process to provide a quick and accurate response.
