In signal converse routine, the computing method of temperature T, PH, ORP, dissolved oxygen DO are as described below:
1) calculating of temperature T (NTC30K)
The corresponding relation of temperature and resistance:
R t = R * EXP ( B * ( 1 / T 1 - 1 / T 2 ) ) = ( AD / 1023 ) * 3.3 * R 0 2.5 - ( AD / 1023 ) * 3.3
Company is above explained as follows:
1, R tthat thermistor is at T 1resistance at temperature;
2, R is that thermistor is at T 2nominal resistance under normal temperature;
3, B value is the important parameter of thermistor, B=3950;
4, EXP is the n power of e;
5, T in formula 1and T 2referring to K degree is kelvin degree, K degree=273.15(absolute temperature)+Celsius temperature.
2) calculating of pH value
A magnitude of voltage corresponding to PH is 59.16mv, the voltage range that 0～14PH is corresponding is :-414.12mv～+ 414.12mv, after (G=3.98) amplified in data pre-processor denoising, corresponding voltage range is :-1.65v～1.65v, after lifting 1.65v must corresponding voltage range be: 0～3.3v.
If do not use correcting fluid to correct to PH:
T＝25；
V PH0＝0v；
V PH7＝1.65v；
V PH14＝3.3v；
Slope calculations K and V thus pH0=0v.
If use PH to correct liquid, carry out PH rectification:
T＝25
The first point: input PH corrects liquid pH value, reads V 1(first PH=7.0);
Second point: input PH corrects liquid pH value, reads V 2(second point PH=4.01);
Slope calculations K and V thus pH0.
PH value computing formula (not temperature compensated):
PH value=7+(V-V pH0) * K
In formula, V is the measured value after data pre-processor is amplified.
PH value computing formula (having temperature compensation):
PH value=7+(V-V pH0) * K-(T-25) * 0.003
3) calculating of ORP value
Seemingly, computing formula is the compute classes of ORP and PH:
ORP = AD - 511 512 * 1.65 * 1000 / 3.98
In formula, AD is monitor value
4) calculating of dissolved oxygen DO
A. single-point calibration (chlorine chlorinity=0, salt salinity=0)
V 0=0; (may for-x.xxx volt)
Single-point:
Step1, electrode are put into the oxygen value that contains of known calibration solution, or air 100%;
Step2, read stable V saturationmagnitude of voltage, gets final product to obtain V saturationcorresponding dissolved oxygen centigrade, V preserved in record saturation.
B. 2 demarcation
Step1, demarcate DO zero point:
Electrode is put into the volumetric solution that known oxygen level value is 0, and V preserved in record 0;
Step2, single-point:
Electrode is put into the oxygen value that contains of known calibration solution, or air 100%.Read stable V saturationmagnitude of voltage, can obtain
V saturationcorresponding dissolved oxygen centigrade, V preserved in record saturation.
C. dissolved oxygen is measured
Step1, record current dissolved oxygen voltage V and Current Temperatures T:
DO%＝(V-V 0)/(V Saturation-V o)
DO mg＝DO mg,Saturation*DO%
In formula, DO mg, Saturationfor standard oxygen dissolving value.
Above-mentioned explanation to the disclosed embodiments, makes the professional and technical personnel of association area can realize or use the present invention, and the General Principle of definition can realize without departing from the present invention in other embodiments in this article.Therefore, the present invention is not limited to embodiment described herein, but the widest interest field consistent with principle disclosed herein and features of novelty.
