OXY-SEN OXYGEN MONITOR

Instruction Manual

SECTION 4.0

OPERATING PROCEDURES

Power On:

Power to the OXY-SEN is applied whenever the instrument is plugged into an AC outlet.

Gas System Pressure Limits

It is imperative that the sample gas pressure to the sensor be kept to under 1 pound per

square inch. There is no automatic pressure correction so operation at a constant pressure will

provide optimum measuring conditions. Vacuums to 12.5 psia are permissible. Any vacuum

level greater than that should be avoided as it will cause irreparable damage to the sensor.

Range Operation

The OXY-SEN Oxygen Monitor operates with two (2) different analog signal output ranges 0-

25% and 0-100%. Selection of the range of operation is done by plugging the monitor's output

cable into one of the two connectors. The connector on the far right labeled "100%"

automatically selects the 0-100% range; selecting the connector to the immediate left labeled

"25%" will provide the 4-20 mADC output over 0-25%. If the 25% output range is selected,

the OXY-SEN will still measure and display oxygen values up to 100%

Sample Connections

The standard OXY-SEN oxygen sensor is designed to be threaded into a hole prepared to

accept a M16X1 thread. As such, there are no conventional gas connections to be made.

Typical applications for the OXY-SEN include glove boxes, reactor vessels, chambers, etc.,

where such threaded holes can be made quite easily. Once the sensor has been properly

installed and the "O" ring properly seated, then the other end of the sensor cable, may be

connected to the bottom of the electronics labeled "Sensor". Alpha Omega Instruments does

offer an optional "T" like flow through gas housing for the OXY-SEN. If this option has been

ordered, the housing will be equipped with quick connect fittings on both the gas inlet and outlet.

These fittings are designed for use with 1/4" OD plastic tubing. The housing may also be

ordered with compression fittings.

Analog Outputs

The OXY-SEN Oxygen Monitor may be equipped with optional analog outputs for use with a

recorder, datalogger, etc., which is a powered 4-20 ma loop output. This output scale is

determined by the range connection selected. The interface cable supplied with the Monitor can

be plugged into the connector labeled "25%" or "100%" on the bottom of the electronics

enclosure. The cable connector location information can be found in Figure 1.0, and the cable

pin-outs in Figure 2.0.

Storage of the Monitor

When the OXY-SEN Oxygen Monitor is not in use, it may be stored in any position. If stored in

an atmosphere where the temperature is greatly different from the temperature where it will be

used, the instrument should be allowed to come into equilibrium with the operating ambient

temperature before use. Under no circumstances should the OXY-SEN Oxygen Monitor or its

sensor be exposed to temperatures below 40° F (5° C) or above 104 ° F (40° C). Doing so will

damage the sensor and void the warranty.
