Diagnostics:
The analyzer continuously monitors
itself and the sensor(s) for problematic conditions.
The display flashes Fault and/or Warning when these
conditions occur.
Display:
The high-contrast LCD provides live meas-
urement readouts in large digits and shows up to four
additional process variables or diagnostic parame-
ters. The display is back-lit and the format can be cus-
tomized to meet user requirements.
LOCAL LANGUAGES:
Rosemount extends its worldwide reach by offering
seven local languages – English, French, German,
Italian, Spanish, Portuguese, and Chinese. Every unit
includes user programming menus; calibration routines;
faults and warnings; and user help screens in all
seven languages. The displayed language can be
easily set and changed using the menus.
CURRENT OUTPUTS:
Two 4-20 mA or 0-20 mA current
outputs are electrically isolated. Outputs are fully scalable
and can be programmed to linear or logarithmic
modes. Output dampening can be enabled with time
constants from 0 to 999 seconds. Output 1 includes
digital signal 4-20 mA superimposed HART (option -HT
only)
Special Measurements:
The Model 1056 offers
measuring capabilities for many applications.
l
Single or Dual Turbidity:
Ideal in municipal appli-
cations for measurement of low-NTU filtered drinking
water. Must be used with Clarity II sensor, sensor cable
and debubbler.
l
4-Electrode Conductivity:
The 1056 is compatible with Rosemount 4-elec-
trode Model 410VP in the PUR-SENSE
family of conductivity sensors. This sensor supports
a wide array of applications and is capable of measuring
a large range of conductivity with one geometric
configuration. Wired to the 1056, this sensor can
measure 2
µ
S/cm to 300mS/cm with an accuracy of 4%
of reading throughout the entire range.
l
4-20mA Current Input:
Accepts any analog current
input from an external device for temperature compen-
sation of measurements and atmospheric pressure
input for partial pressure correction of oxygen.
l
Selective Ions:
The analyzer is able to measure
ammonia and fluoride using commercially available
ion-selective electrodes. All analyzers with installed pH
boards can be programmed to measure selective ions.
l
pH Independent Free Chlorine:
With Rosemount
498Cl-01 sensor, the analyzer is able to measure free
chlorine with automatic correction for process pH with-
out the need for a pH sensor.
l
Inferential pH:
The analyzer is able to derive and
display inferred pH (pHCalc) using two contacting con-
ductivity signal boards and the appropriate contacting
conductivity sensors. This method will calculate the
pH of condensate and boiler water from conductivity
and cation conductivity measurements.
l
Differential Conductivity:
Dual input conductivity
configurations can measure differential conductivity.
The analyzer can be programmed to display dual
conductivity as ratio, % rejection, or % passage.
