DESCRIPTION AND SPECIFICATIONS
1.2 SPECIFICATIONS
Case: Polycarbonate (panel mount and pipe/wall mount);
NEMA 4X/CSA 4 (IP65)
Dimensions
Panel (code -10): 6.10 x 6.10 x 3.72 in.
(155 x 155 x 94.5 mm)
Surface/Pipe (code -11): 6.23 x 6.23 x 3.23 in.
(158 x 158 x 82 mm); see page 15 for dimensions
of pipe mounting bracket.
Conduit openings: Accepts PG13.5 or 1/2 in. conduit
fittings
Ambient Temperature: 32 to 122°F (0 to 50°C). Some
degradation of display above 50°C.
Storage Temperature: -4 to 158°F (-20 to 70°C)
Relative Humidity: 10 to 90% (non-condensing)
Weight/Shipping Weight: 2 lb/3 lb (1 kg/1.5 kg)
Display: Two line, 16-character display. Character height:
4.8 mm; first line shows process variable (pH, ORP,
conductivity, % concentration, oxygen, ozone, chlo-
rine, or monochloramine), second line shows process
temperature and output current. For pH/chlorine com-
bination, pH may also be displayed. Fault and warn-
ing messages, when triggered, alternate with temper-
ature and output readings.
During calibration and programming, messages,
prompts, and editable values appear on the two-line
display.
Temperature resolution: 0.1°C (≤99.9°C);
1°C (≥100°C)
Hazardous Location Approval: For details, see specifi-
cations for the measurement of interest.
RFI/EMI: EN-61326
DIGITAL COMMUNICATIONS:
HART —
Power & Load Requirements: Supply voltage at
the transmitter terminals should be at least 12
Vdc. Power supply voltage should cover the volt-
age drop on the cable plus the external load
resistor required for HART communications (250
Ω minimum). Minimum power supply voltage is
12 Vdc. Maximum power supply voltage is 42.4
Vdc. The graph shows the supply voltage
required to maintain 12 Vdc (upper line) and 30
Vdc (lower line) at the transmitter terminals
when the current is 22 mA.
Analog Output: Two-wire, 4-20 mA output with
superimposed HART digital signal. Fully scalable
over the operating range of the sensor.
Output accuracy: ±0.05 mA
FOUNDATION FIELDBUS —
Power & Load Requirements: A power supply volt-
age of 9-32 Vdc at 13 mA is required.
