In signal converse routine, temperature T, PH, ORP, dissolved oxygen DO computational methods as described below:
1) calculating (NTC30K) of temperature T
The corresponding relation of temperature and resistance:
Company above is explained as follows:
1、RtIt is that critesistor is at T1Resistance at temperature；
2, R is that critesistor is at T2Nominal resistance under room temperature；
3, B value is the important parameter of critesistor, B=3950；
4, EXP is the n power of e；
5, T in formula1And T2Refer to K degree and kelvin degree, K degree=273.15(absolute temperature)+Celsius temperature.
2) calculating of pH value
One magnitude of voltage corresponding for PH is 59.16mv, voltage range corresponding for 0～14PH is :-414.12mv～+414.12mv, amplifying after (G=3.98) through data pre-processor denoising, corresponding voltage range is :-1.65v～1.65v, obtains corresponding voltage range and is: 0～3.3v after lifting 1.65v.
If not using correcting fluid to correct PH, then:
T=25；
VPH0=0v；
VPH7=1.65v；
VPH14=3.3v；
Thus slope calculations K and VPH0=0v.
If using PH to correct liquid carry out PH rectification, then:
T=25
First point: input PH corrects liquid pH value, reads V1(first PH=7.0)；
Second point: input PH corrects liquid pH value, reads V2(second point PH=4.01)；
Thus slope calculations K and VPH0。
PH value computing formula (not temperature compensated):
PH value=7+(V-VPH0) * K
In formula, V is the measured value after data pre-processor is amplified.
PH value computing formula (has temperature-compensating):
PH value=7+(V-VPH0) * K-(T-25) * 0.003
3) calculating of ORP value
The calculating of ORP and PH is similar, and computing formula is:
In formula, AD is monitor value
4) calculating of dissolved oxygen DO
A. single-point calibration (chlorine chlorinity=0, salt salinity=0)
V0=0；(being likely-x.xxx volt)
Single-point:
Step1, electrode put into known calibration solution containing oxygen value, or air 100%；
Step2, read stable VSaturationMagnitude of voltage, VSaturationCorresponding dissolved oxygen centigrade, record preserves VSaturation。
B. 2 demarcation
Step1, demarcation DO zero point:
It is the volumetric solution of 0 that electrode puts into known oxygen-containing value, and record preserves V0;
Step2, single-point:
Electrode put into known calibration solution containing oxygen value, or air 100%.Read stable VSaturationMagnitude of voltage, can obtain
VSaturationCorresponding dissolved oxygen centigrade, record preserves VSaturation。
C. dissolved oxygen is measured
Step1, record current dissolved oxygen voltage V and Current Temperatures T, then:
DO%=(V-V0)/(VSaturation-Vo)
DOmg=DOmg,Saturation*DO%
In formula, DOmg,SaturationFor standard oxygen dissolving value.
Described above to the disclosed embodiments, makes the professional and technical personnel of association area be capable of or use the present invention, and the General Principle defined in this article can realize without departing from the present invention in other embodiments.Therefore, the invention is not limited in embodiment described herein, but the widest interest field consistent with principle disclosed herein and features of novelty.
