Special function
Special function
(DA 230/S)
The special software provides for
the automatic recording of
measurements during discontinuing processes, such as when
measuring a pouring stream. The
I N F R A R E D T E M P E R A T U R E SOL UT ION S
measurement begins automatically when the set limit is exceeded. The recorded value is
displayed when the time required for the measurement is over.
Smoothing time constant
Min. and max. value memory with
internal or external reset.
Switch point and hysteresis (limit contacts)
Linearisation function with up to
10 inflection points. Validity check
Type DA 230/S for automatic
recording of measured values
Optional
Accessory
”CellaMevis“
PC software for transmission, display and storage of measured
values with a single PC.
