GCG-1000 dust concentration sensor

GCG-1000 dust concentration sensor dust concentration sensor GCG-1000 concentration sensor dust sensor dust concentration sensor has been competing flowers bloom you do not always stand in a daze GCG-1000 if the dust concentration sensor to set their own limits, then there would be no life Limit your play fences 182-6476-7823 Yin Jinhua I. Features:? continuous detection of the concentration of flammable gas mixtures in the environment flammable dust floating in existence, with fast and accurate measurement, high sensitivity, local display, remote signal transmission performance, stability, and so on can be preset K value functions and features can be used with a variety of supporting the use of monitoring systems. Second, the principle: the outside air at the blower suction inlet port into the sensor through the dark labyrinth. When the dust floating in the air in a dark room by irradiating parallel light emitted from the laser generator, the scattered light intensity is proportional to the dust concentration, the scattered light through photoelectric conversion is converted into a photocurrent, the MPU photocurrent integrating circuit converted into scattered light intensity is proportional to the number of optical pulse. Calculate the number of pulses to measure the relative concentration of dust, pre-K through calibration values ??set on the keyboard, you can display the concentration of dust in the air (mg / m3) directly on the digital display at work. The main technical parameters: Measuring range: 0.1 ~ 1000) mg / m3, measured relative error ≤15% sample flow error: ≤ ± 2.5%, sampling flow stability: ≤ ± 5%, the sample flow rate: 15L / min, the working voltage: DC (9 ~ 24) V (intrinsically safe power supply), the operating current: ≤250mA, output signal format: frequency (200 ~ 1000) Hz, explosion-proof type: Exib I, protection class: IP54, dimensions: 250 × 220 × 120mm , Weight: 5kg coal safety signs Number: MFA060011 quality assurance, price concessions, in cooperation with the coal that you do not regret the choice! Warm welcome to new and old customers to inquire to buy!
