Conductivity/Resistivity Analyzer/Controller

Performance under reference operating conditions

Display Accuracy:

Standard Ranges (Conductivity/Resistivity); ±0.5% of reading.

Wide Ranges (Conductivity); ±0.5% of reading or 0.02% of span.

Concentration; ±0.5% of span, ±1% conformity to conductivity vs. concentration data tables.

Output accuracy: Adjustable to within 0.01 mA, repeatable to within ±0.1% of span.

Reference Operating Conditions: 25 ±1 °C; 10 to 40% RH; 120 or 240 Vac; process temp 25 °C measured

Operating Influences under normal operating conditions

Effect on accuracy (% of span): Temperature: 0.05% per °C; RH: <1%; Line Voltage: <0.1%

per volt; Power Loss: memory retention by EEPROM (no batteries).

2.1.7 Outputs

Standard alarm/control relays

Two SPDT Form C general purpose relays rated 0.6 amps at 120/240 Vac, 0.6 amps at 110 Vdc, 2 amps at 30 Vdc. Maximum switching power for ac, 125 VA resistive; for dc, 60W resistive.

Optional alarm/control relays

 

9782C- _ _ - R2:

Two additional SPDT Form C, rated at 3 amps at 120 Vac

 

or 28 Vdc, no analog outputs

9782C- _ _ - R0:

Two hermetically sealed Form C, rated at 3amps at 120 Vac

 

or 28 Vdc, plus one analog output 0 to 1 Vdc or 0 to 10 Vdc

 

or isolated 4 to 20 mA.

Optional analog outputs

One, two or three 4 to 20 mA outputs are available via an optional plug-in circuit card and program module. Isolated from ground, inputs and one another.

Maximum isolation voltage: 240 Vac (will withstand 1500V hi-pot test).

Output adjustment: to within 0.01 mA.

Repeatability: ±0.1% of span. 600 ohm maximum load resistance. Proportional to selected output

range.

 

9782C- _ _ - 00:

None

9782C- _ _ -VC:

One analog output: 0 to1V or 0 to10 Vdc or isolated 4 to20

 

mA dc (600 ohms maximum load)

9782C- _ _ - C2:

Two analog outputs: both isolated 4 to 20 mA dc.

9782C- _ _ - C3:

Three analog outputs: all 4 to 20 mA dc

One analog output also available in combination with optional relays (see above).
