Product Description
The AMI Turbitrace is used for the measurement of low level turbid-
ity in pure and ultra pure water.
Turbidity is a measure of how much of the light traveling through
water is scattered by suspended particles. The scattering of light in-
creases with increasing suspended solid. The intensity of light scat-
tered at 90° as a beam of light passes through a water sample is
measured and indicates turbidity of the sample.
Two signal outputs programmable for measured values (freely scal-
able, linear or bilinear) or as continuous control output (control pa-
rameters programmable).
Current loop:
Maximal burden:
Third signal output available as an option. The third signal output
can be operated as a current source or as a current sink (selectable
via switch).
Two potential-free contacts programmable as limit switches for
measuring values, controllers or timer for system cleaning with au-
tomatic hold function. Both contacts can be used as normally open
or normally closed.
Maximum load: 1 A / 250 VAC
One potential free contact.
Alternatively:
Open during normal operation, closed on error and loss of
power.
Closed during normal operation, open on error and loss of
power.
Summary alarm indication for programmable alarm values and in-
strument faults.
For potential-free contact to freeze the measuring value or to inter-
rupt control in automated installations (hold function or remote-off).
No data loss after power failure. All data is saved in non-volatile
memory. Over voltage protection of in- and outputs.Galvanic sepa-
ration of measuring inputs and signal outputs.
USB Interface for logger download.
Third signal output (can be used in parallel to the USB interface)
