ZHJ - R203 dust particle counter online multi-point detection system
Detection system is used to detect dust-free workshop air cleanliness level professional metering instruments, Technical indicators in line with national metrology Administration issued the JJF1190-2008 "dust particle counter calibration specification" the provisions of requirements. For cleanliness space real time monitoring, System in clean interior the multiple sensors carries out administration, Include: remote control, data storage, historical data query, data analysis and Draw tendency chart. System can meet the pharmaceutical industry, electronics industry, precision machinery manufacturing industry, food industry, Optics and precision machining of aerospace and other fields, Precision testing required in clean room (area) cleansing grade detection needs to be.
一. System is introduced:
Detection systems include: The dust particle sensor transmitter; Built-in flow control system; A data processing system; The control system and display alarm system.
(1) The dust particle sensor transmitter machine using particle light scattering principle, Light source adopts imported semiconductor laser emission, Imported semiconductor photosensitive tube to receive, Improve test sensitivity and accuracy. To face clean the space particles concentration in real time, continuous monitoring. Sampling flow: 2.83 / points, or 28.3 litres per minut. Grain size channels: 0.3; 0.5; 1.0; 5.0μm any two grades. Accord with JJF1190-2008“the dust particle counter calibration specification”and GB/T6167-2007“the dust particle counter performance test method”Various technical indicators by the rules
(2) Built-in rate of flow control system: In order to detect sampling flowrate, Throttle valve control sampling flowrate, ensure the sampling flowrate 2.83 liters/min (28.3 litres/divided into extraposition vacuum pump)
(3) Signal processing: Will the dust particle counter transmitter collect of analog signals into digital signals, and according to the actual flowrate convert to into cubic meter data, matrixing and statistics.
(4) Control system: detection and control sampling, transfinite alarm.
(5)display system: display all test parameters, can made ICONS curves, and print out the result.
