Brief introduction: GCG1000 type dust concentration sensor is a kind of absorption, absorbing the domestic and foreign advanced technology of dust, used to swim in the dark room dust floating dust exposure light source, the scattering intensity is proportional to the dust concentration, the principle of the intensity of light will be scattered light is converted into electrical signals, and the relative quality of dust concentration is calculated, and then through the preset values of the parameters, can be directly calculated the mass concentration of dust. Travel through the liquid crystal display translates into frequency signal or current signal output. Dust concentration can be preset alarm value, when the measurement of dust concentration reaches the value, the output a warning signal immediately, in order to remind the staff start corresponding dust measures in a timely manner. GCG1000 type dust concentration sensor is suitable for the coal dust, and other dangerous, flammable environments, such as on-site Features: 1. The rated working current is small, greatly reduce the burden of the substation power supply, and can be installed in the location of the farther away from the substation, in the case of rated sampling flow working current is small. 2. Wide range of input voltage, and can be applied to the coal mine substation, instrument in the input voltage is 12 v ~ 24 VDC (power) within the scope of works; 3. The high accuracy of measurement: adopting sectional control algorithm, according to the proportion of different concentration size automatically using different coefficient calculation, at the same time, strengthen the function of temperature compensation, improve the accuracy of the measurement; 4. With functions of automatic calibration zero and zero drift can be set up calibration time; 5. Have the function of the soft starting mode, reduce the impact on the power supply when starting the instrument. Technical parameters: Measuring range: 0 mg/m3 ~ 1000 mg/m3 Measuring the relative error: plus or minus 10% Sampling flow: 18 l/min Sampling flow error: plus or minus 2.5% Transfinite alarm and 12 + 3 v DC output signal Output: 200 ~ 1000 Hz frequency, pulse width is greater than 0.3 ms. Output current: (4 ~ 20 mA Working voltage: 12 ~ 24 V DC (Ann), the working current: ma 170 or less.
