Current I = SAE class / Error Voltage U =
I = 18,99 mA SAE 13,8 U = 9,50 V
I = 19,10 mA SAE 13,9 U = 9,55 V
I = 19,20 mA SAE 14,0 U = 9,60 V
19,2 mA < I < 19,8 mA Not defined 9,60 V < U < 9,90 V
19,8 mA < I < 20 mA No measured value 9,90 V < U < 10 V
If the contamination class is given acc. to SAE, the current I or voltage U can be
calculated:
I = 4.8 mA + SAE class x (19.2 mA - 4.8 mA) / 14
U = 2.4 V + SAE class x (9.6 V - 2.4 V) / 14
If the contamination class is given acc. to SAE, the current I or voltage U can be
calculated:
SAE class = (I - 4.8 mA) x (14/14.4 mA)
SAE class = (U - 2.4 V) x (14/7.2 V)
SAE A-D
The SAeMAX value is the highest class in any of one of the four SAE A-D classes
(respectively >4 µm
(c)
,>6 µm
(c)
,>14 µm
(c)
,>21 µm
(c)
).
The signal is updated after the measuring period has elapsed (the measuring period
is set in the PowerUp menu, factory setting = 60 s).
The
SAeMAX signal is output depending on the maximum SAE class.
Example:
SAE classes SAEMAX (SAE A-D)
SAE 6.1A / 5.7B / 6.0C / 5.5D
For basic information about cleanliness classes, see page 96 ff.
The SAE classification contains integer values only. Better change / trend
recognition is based on a resolution of 0.1 contamination classes.
To convert a decimal value to an integer, the decimal value has to be rounded up.
For example: a readout of SAE 10.7 is, according to SAE 4059 (D), a class SAE 11.
