4, realize thermostatic control.In digestion process, the temperature of heating transmits signals to control circuit through temperature sensor, by the A/D conversion chip on the control circuit analog quantity is converted to digital quantity and sends single-chip microcomputer to; The single-chip microcomputer internal processes adopts the PID (being called for short PID) in the automatic control mode to regulate, and response is fast, and tracking performance is good, can effectively suppress the heating curves vibration.Difference according to heating-up temperature and design temperature changes the heating current size, thereby makes the measurement temperature trend towards set temperature value, realizes thermostatic control.
5, fast, the circuit board of control chip processing speed has anti-preferably electromagnetic interference (EMI) (being called for short EMI) characteristic: the microprocessor unit of control circuit board is a STC series of high speed single-chip microcomputer, is a new generation's high speed, low-power consumption, superpower jamproof single-chip microcomputer; Between control circuit and heater circuit, take the measure of photoelectric coupler isolation, prevent of the interference of big electric current control signal.
6, temperature measurement accuracy is high, temperature-measuring range is wide.The temperature that in whole digestion process, heats is a series of continually varying amounts; In order to guarantee the accuracy of data processed result, the A/D conversion chip adopts 16 precision high-speed converters, and SF 20Hz～500Hz is able to programme; Have 0.0015% non-linear, resolution is 0.0023 ℃; Temperature sensor adopts K type thermopair, temperature-measuring range :-200 ℃～1300 ℃, have that measuring accuracy height, measurement range are wide, a simple structure, advantage easy to use.
7, clear up the completion automatic hold function.The control chip internal processes is provided with time control unit, need not manual work and carries out timing, sets to stop heating heat time heating time after the arrival automatically.
The circulation of COD intelligent digestion appearance LCDs shows heating-up temperature, heat time heating time, can set up heat time heating time and heating-up temperature on their own according to user's needs.Evenly heating, thermostatic control are simple to operate, stable and reliable for performance, are widely used in the water quality detection of industries such as environmental protection, medical treatment, health, food, tap water, papermaking, wastewater treatment, printing and dyeing, petrochemical industry, metallurgy, universities and colleges.
Adopt the COD intelligent digestion appearance of 12 heating-range mouths in this explanation; Its workflow is following: according to GB (11914-89) COD method of operating; With water sample with clear up reagent and be added in the glass heats pipe, with connecting condenser pipe on the heating tube, be put in the heating tank then again.Opening power master switch is at first opened the CS of heating tank again, configures required digestion time and temperature according to actual conditions through control knob then, checks set condition through liquid crystal display.After digestion time arrives, stop heating automatically.Heating tube and condenser pipe are taken out from the kitchen range mouth, place on the heating tube support, carefully take off condenser pipe, directly titration in heating tube then after making its cooling.Digestion process need not the personnel guard, arrives digestion time and stops automatically, and automaticity is high, has improved work efficiency, has saved resource.
