Input System Specifications
Aux Systems There are 2 Aux input systems that allow digital or analog (0-
1.0VDC, 0-5.0VDC, or 4-20mA) configuration.
Aux System
Type
Digital Analog
Range dry contact open/
close
0 -1.0 VDC, 0-5.0 VDC, or 4-20mA
Accuracy n/a 0-1.0VDC: ± 3% ± 10 mV
0-5.0VDC: ± 3% ±15 mV
4-20 mA: ± 3% ±100μA
Resolution n/a user selectable (0), (0 .0), or (0.00)
Probe assembly 5562 (DO, temperature, pH, ORP, and conductivity sensors)
Probe assembly 5561 (DO and temperature sensors)
Cable grade
military-spec (MS) connector
Cable lengths 4, 10, 20 m (special order up to 100m for DO and temp only)
Temperature
Sensor type
10,000 ohm @ 25°C thermistor
Range 0-45°C (32-113°F)
Accuracy ± 0.2°C
Resolution 0.1°C
Dissolved Oxygen
Sensor type
Membrane covered, steady-state polarographic
Range 0 to 500% air saturation
0 to 60 mg/L
Accuracy ±2% or ± 0.2 mg/L, whichever is greater for 0-200%
±6% of reading for 200-500%
Resolution 0.1% (0.0-99.9%); 1% (> 99.9)
0.01 mg/L (0-10 mg/L); 0.1 mg/L (10-60 mg/L)
Response Time 95% of reading in 17 seconds for 2.0 mil PE membrane;
95% of reading in 36 seconds for 2.0 mil Teflon membrane.
Allow approximately 10-15 minutes after 5200A is powered
on, or the DO sensor is serviced, for the polarographic sensor
to stabilize.
Introduction
Flow requirements minimum flow rate of 3 inches per second or 7.62 cm/second
for 2.0 mil PE membrane; 6 inches per second or 15.24 cm/
second for 2.0 mil Teflon membrane
Other Automatic salinity compensation for DO readings when a
conductivity sensor is in use and enabled. Manual salinity
compensation for DO readings when a conductivity sensor is
not in use.
