Oxymitter 4000

Instruction Manual

IM-106-340, Rev. 4.0 May 2006

IMPS 4000 (OPTIONAL)

SPS 4001B (OPTIONAL)

Information on the IMPS 4000 is available in the IMPS 4000 Intelligent Multiprobe Test Gas Sequencer Instruction Manual.

The SPS 4001B Single Probe Autocalibration Sequencer provides the capability of performing automatic, timed or on demand, calibrations of a single Oxymitter 4000 without sending a technician to the installation site.

Mounting

The SPS 4001B is fully enclosed in a NEMA cabinet suited for wall-mounting.

 

This cabinet provides added protection against dust and minor impacts. The

 

SPS 4001B consists of a manifold and a calibration gas flowmeter. The mani-

 

fold provides electrical feedthroughs and calibration gas ports to route power

 

and signal connections and calibration gases to and from the sequencer. In

 

addition, the manifold houses two calibration gas solenoids that sequence the

 

gases to the Oxymitter 4000, a pressure switch that detects low calibration

 

gas pressure, and two PC boards. A terminal strip housed within the terminal

 

cover provides convenient access for all user connections.

 

Components optional to the SPS 4001B include a reference air flowmeter and

 

pressure regulator. The reference air flowmeter indicates the flow rate of

 

reference air continuously flowing to the Oxymitter 4000. The reference air

 

pressure regulator ensures the instrument air (reference air) flowing to the

 

Oxymitter 4000 is at a constant pressure [20 psi (138 kPa)]. The regulator

 

also has a filter to remove particulates in the reference air and a drain valve to

 

bleed the moisture that collects in the filter bowl.

 

Brass fittings and Teflon tubing are standard. Stainless steel fittings and

 

tubing are optional. Also, disposable calibration gas bottles are available as

 

an option or can be purchased through a local supplier.

Operation

The SPS 4001B works in conjunction with the Oxymitter 4000's CALIBRA-

 

TION RECOMMENDED feature to perform an autocalibration. This feature

 

automatically performs a gasless calibration check every hour on the Oxymit-

 

ter 4000. If a calibration is recommended and its contact output signal is set

 

for "handshaking" with the sequencer, the Oxymitter 4000 sends a signal to

 

the sequencer. The sequencer automatically performs a calibration upon

 

receiving the signal. Thus, no human interface is required for the automatic

 

calibration to take place. For further SPS 4001B information, refer to the SPS

 

4001B Single Probe Autocalibration Sequencer Instruction Manual.
