Mechanical
Sensor-to-Analyzer Distance ...... 300 ft. (91 m) maximum
Power Requirements .................. 90-130 VAC, 50/60 Hz. (10 VA max.) or
180-260 VAC, 50/60 Hz. (10 VA max.)
Calibration Methods:
DRY-CAL................................ Enter GLI-certified cell constant “K” value and
temperature “T” factor of the sensor.
1 POINT SAMPLE .................. Enter one reference solution value or one
sample value (determined by laboratory
analysis or a comparison reading).
ZERO ..................................... With the dry sensor in air, press keys to
initiate automatic system zeroing.
Analog Outputs .......................... Two isolated 0/4-20 mA outputs; each with
0.004 mA (12-bit) resolution and capability
to drive up to 600 ohm loads
NOTE:
Each output can be assigned to represent Sensor A or B’s selected
parameter (conductivity, resistivity or TDS), Sensor A or B’s tem-
perature or a calculated Sensor A and B measurement (% rejection,
% passage, ratio A/B, ratio B/A, difference A-B, or difference B-A).
Parameter (or calculated measurement) values can be entered to de-
fine the endpoints at which the minimum and maximum mA output
values are desired (range expand). During calibration, both outputs
can be selected to hold their present values, transfer to preset values
to operate control elements by an amount corresponding to those
values, or remain active to respond to the measured value.
Communication: RS-232 ........... Enables configuration and retrieval of measured
data for one analyzer using IBM-compatible
PC and optional GLI software tool kit
HART.............. Enables configuration and retrieval of measured
data for multiple analyzers over a communi-
cation link using an appropriate hand-held
terminal or data system with HART software
Memory Backup (non-volatile) .... All user settings are retained indefinitely in
memory (EEPROM)
EMI/RFI Conformance................ Exceeds US and meets European standards
for conducted and radiated emissions and
immunity; certified CE compliant for appli-
cations as specified by EN 50081-1 for
emissions and EN 50082-2 for immunity
Electrical Certifications:
General Purpose (pending) ..... UL, C-UL, FM, and CENELEC
Division 2 (pending) ................ UL, C-UL, and FM: Groups A, B, C, D, F, and G
Zone 2 (pending) .................... CENELEC: Group IIC
Accuracy .................................... 0.1% of span
Stability...................................... 0.05% of span per 24 hours, non-cumulative
Repeatability .............................. 0.1% of span or better
Temperature Drift ....................... Zero and Span: less than 0.03% of span/
°
C
Enclosure................................... NEMA 4X; polycarbonate face panel, epoxy-
coated cast aluminum door and case with four
1/2 inch (13 mm) conduit holes; nylon mount-
ing bracket, and stainless steel hardware
Mounting Configurations............. Panel, surface, and pipe (horizontal and
vertical) mounting
Net Weight ................................. 3.5 lbs. (1.6 kg) approximately
