The optional air purge, when installed along with user supplied components, is designed to equip the instrument

enclosure with Type Z protection per Standard ANSI/NFPA 496-1986. This reduces the classification within the

enclosure from Class I, Division 2 (normally non-hazardous) to non-hazardous, thus permitting installation in a location

classified Class I, Groups A, B, C, D, Division 2. This method of protection is recognized in Article 500-1 of the National

Electrical Code (NEC, ANSI/NFPA 70).

The oxygen sensors and interconnecting cable used with the Models 7001D and 7002D Oxygen Monitors are non-

incendive in normal operation and comply with the requirements of Articles 501-3 (b)(1) c and 501-4 (b), Exception of the

National Electrical Code, ANSI/NFPA 70-1987, for installation in Class I, Groups A,B,C,D, Division 2 classified locations.

NOTES

NTRODUCTION

748039-U Rosemount Analytical December 2000

Model 7001D, 7002D Oxygen Monitors

1.1 OVERVIEW

Model 7001D and 7002D Oxygen Monitors (Figure 1-1) automatically and continuously

measure the concentration of dissolved oxygen in water or non-aqueous solution. The

determination is based on measurement of the electrical current developed by an

amperometric sensor in contact with the sample.

The monitors provide direct readout, on a front-panel display, of dissolved oxygen. The

Model 7001D readout is in parts per thousand million (ppb) by weight, while the Model

7002D readout is in parts per million (ppm) by weight. Alarms and a potentiometric output

are standard features. The full scale range of the alarms and the potentiometric output are

each independently selectable. Thus, the range of the potentiometric output may be

changed without the need to readjust alarm setpoints.

The oxygen monitor system consists of a sensor, a chamber, and an amplifier module. The

sensor is housed within the chamber and is connected to the amplifier by a multi-conductor

shielded cable.

1.2 AMPLIFIER MODULE

The amplifier module conditions the sensor output signal to provide direct readout of

dissolved oxygen in parts per thousand million (ppb) (Model 7001D) or parts per million

(ppm) (Model 7002D) by weight. It also contains current-measuring circuitry, operating

controls, digital display, alarms and signal output provisions.

The module is designed for panel mounting. An accessory kit (PN 622622) permits the

amplifier module to be mounted on a vertical or horizontal pipe. An accessory kit (PN

652117) permits wall (surface) mounting. An optional air purge is designed to meet

requirements for NFPA 496 Type Z air purge (see specifications) .

An accessory board (PN 621023) provides a field-selectable 0 to 20 milliampere or 4 to 20

milliampere isolated current output.
