PCE-CPC 100 Particle Counter
Description
The PCE-CPC 100 online particle counter adopts the principle of optical scattering, which can accurately detect and calculate the number of suspended particles of different particle sizes in the air per unit volume. It can output the particle count of 5 channels of 0.3m, 0.5m, 1.0m, 5.0m and 10m at the same time (default unit is pcs/28.3L, available to switch unit to be pcs/m³).
Features
Real-time output particle quantities of 0.3m, 0.5m, 1.0m, 5.0m, 10m in pcs/28.3L or pcs/m³. Sound and light alarm once particle quantity exceeds the set threshold. ModBus communication protocols available. Real-time display cleanroom ISO 14644-1 grade level. Output units switchable between pcs/28.3L and pcs/m³. Constant flow gas sampling system to ensure stable sampling. Industrial grade laser for high reliability.
Working Principle
Air sampling is carried out by a fan. When the particles in the sampled gas pass through a light source (laser) and other beams, light scattering occurs; the scattered light is converted into an electrical signal (pulse) through a photoelectric converter, and the larger the particle, the pulse signal is obtained. The larger the wave value (wave peak value), the number of particles with different particle sizes can be obtained through the wave peak value and the number of pulses at this time. According to the block diagramme, the light source part of PCE-CPC 100 consists of a laser tube that emits light to detect particles and a drive circuit, the detection part consists of a photosensitive element that receives reflected light and an amplifier circuit, and the data processing and communication output are completed by a microprocessor. The particle detection of PCE-CPC 100 is the gas flow generated by the operation of the fan, and the particles pass through the detection chamber. The light from the laser tube will be scattered by the particles and converted into electrical signals by the photosensitive device. After the electrical signal is processed by amplifying circuit, filtering and MCU, it will be converted into digital signal output.
