Sensor suppliers provide many kinds of csensors to buyers. Here are some of the waterproof C02 sensors that sensor wholesalers usually have in stock.
This sensor is ideal for measuring and estimating the concentration of carbon dioxide in any environment. It has an infrared energy-emitting element. This element, together with a detector, is mounted inside the sensor housing.
As the air containing carbon dioxide passes through the sensing chamber, the IR will be obstructed by C02 molecules. This obstruction leads to a drop in the quantity of abundant energy that can be recognized by the detector.
The basic component of an NDIR CO2 sensor is a measurement cell with a mechanical part, a gas filter, and an optical filter. The mechanical part comprises a measurement chamber with windows at both ends. One window is for the IR beam entrance, while the other is for emission and measurement. NDIR sensors also allow users to make a selection for variable gases by using a gas filter. This filter prevents other gases from interfering with the measurement process.
NDIR C02 sensors are preferred when high accuracy is required. Other advantages it has over other C02 sensors include longevity, low maintenance frequency, and versatility.
Capacitive carbon dioxide sensors are made of two conducting plates separated by a dielectric material. They measure C02 concentration based on the fluctuation in dielectric constant caused by the absorption of the gas.
When carbon dioxide gas comes in touch with the dielectric, it interacts with molecules and generates dipoles. These dipoles can be grouped in specific orientations dependent on the polarization rate of the gas molecules. This change results in an element with a new dielectric constant value that can be computed. This new value is, in turn, used to determine the concentration of carbon dioxide in the environment.
Capacitive carbon dioxide sensors are often used because of their advantages, such as high dependability, non-invasiveness, competency, and cost-effectiveness. Its ability to work even in extreme conditions makes it for several applications.
This sensor is a compact solution that performs well for the long term in a broad spectrum of environments. The carbon dioxide diffusion within the sensor through a membrane plays an integral role in the sensing feature. After diffusion, the gas dissolves in a conductive liquid electrolyte, which will give rise to an electrochemical reaction with C02. This reaction produces a current density, which is directly proportional to the concentration of carbon dioxide.
The current is then measured with the help of a potentiostat. The instrument extracts pertinent information from the current and utilized it for the calculation of C02 concentration.
Infrared C02 sensors are capable of measuring concentrations in ambient air without the necessity for calibration or adjustment. An ambient air sample flows across the sensor's optics and the measurement chamber and exits through an exhaust port.
The sample volume is defined exponentially by the optical paths of the two beams of infrared light. An unbiased measurement of the C02 concentration is provided by the ratio of the two infrared beams.
These sensors are useful in varied applications, primarily in those industries where carbon dioxide use is vital for production. Because it requires little to no maintenance, it is also often used in greenhouses.
