LPS10 - 19 - V1.0
8 MEASUREMENT WITH ANALOG OUTPUT (only LPS10MA…)
Calculation of the global irradiance E
e
(W/m
2
) as a function of the analog output value
V
out
(in V) or I
out
(mA).
Analog output Global irradiance
0…20 mA E
e
= E
is
+ [(E
fs
– E

) • I

/20]
4…20 mA E
e
= E
is
+ [(E
fs
– E
is
) • (I
out
– 4)/16]
0…1 V E
e
= E

0…5 V E
e
= E
is
+ [(E

) • V

/5]
0…10 V E
e
= E
is
+ [(E
fs
– E
is
) • V
out
/10]
Where E
is
and E
fs
are respectively the global irradiance (in W/m
2
) corresponding to
the analog output initial and full scale.
Considering the default values E
is
= 0 and E
fs
= 2000 W/m
2
, the previous formulas
can be simplified into the following ones:
Analog output Global irradiance
0…20 mA E
e
= 100 • I
out
4…20 mA E
e
= 125 • (I
out
– 4)
0…1 V E
e
= 2000 • V
out
0…5 V E
e
= 400 • V
out
0…10 V E
e
= 200 • V
out
