detector de praf/detector PM2.5/detector PM10
· Senzor laser de înaltă performanță importat, precizie ridicată a măsurătorilor, repetabilitate bună, stabilitate bună;
· Praful este detectat prin principiul împrăștierii laserului, care este convertit în semnal de date de ieșire de către microprocesor;
· Algoritm inteligent de compensare a temperaturii și umidității și a punctului zero, funcție de calibrare automată; funcție de autotest la pornire;
· Fluxul de lucru nominal este mic, ceea ce reduce considerabil sarcina managerului general de la fața locului;
· Intervalul de tensiune de intrare este larg, iar instrumentul poate funcționa normal în intervalul de tensiune de intrare de 15V~36VDC.
·Parametrii pot fi ajustați cu telecomanda cu infraroșu, care poate realiza reglarea fără a deschide mașina și facilitează reglarea.
· Curent 4-20MA, ieșire comutatoare semnal RS485, realizează transmisie pe distanțe lungi:
· Design mecanic de primă clasă, camera de aer este fabricată din profile de aluminiu de înaltă rezistență, de calitate militară, rezistente la cânepă și coroziune:
LZG-PM-200 fixed dust detector adopts the principle of laser scattering, diffuse sampling to detect the concentration of suspended particles PM2.5 and PM10 in the air. Independent high-precision imported 16-bit AD chip and unique signal processing algorithm, the measurement data accuracy is higher and more stable. Its detector is made up of: sensor, amplifying circuit, structural parts etc., also can connect equipments such as sound and light alarm externally. The output signal can be divided into: bus system, split line system, switch signal. It can form a gas detection and alarm system with the alarm produced by our company or DCS, PLC and other systems.
It is suitable for dust prevention monitoring of labor departments of industrial and mining enterprises, environmental protection testing, dust concentration monitoring at exhaust outlets, temporary online dust removal/granulation process research total concentration detection, underground coal mine workplaces, flour workshops, pulverized coal production workshops, open/semi-open Measurement of dust concentration in spaces (tunnels), storage yards and other places.
· Imported high-performance laser sensor, high measurement accuracy, good repeatability, good stability;
· The dust is detected by the principle of laser scattering, which is converted into data signal output by the microprocessor;
· Intelligent temperature and humidity and zero point compensation algorithm, automatic calibration function; power-on self-test function;
· The rated work flow is small, which greatly reduces the burden on the on-site general manager;
· The input voltage range is wide, and the instrument can work normally within the input voltage range of 15V~36VDC.
·The parameters can be adjusted by infrared remote control, which can realize the adjustment without opening the beauty and make the adjustment easier.
· 4-20MA current, RS485 signal switch output, realize long-distance transmission:
· First-class mechanical design, the air chamber is made of military-quality high-strength aluminum profiles, resistant to hemp and corrosion:
