Oxymitter 5000
b. Components (Figure 1-5)
The SPS 4000 consists of a manifold and a
calibration gas flowmeter. The manifold pro-
vides electrical feedthroughs and calibration
gas ports to route power and signal connec-
tions and calibration gases to and from the
sequencer. In addition, the manifold houses
two calibration gas solenoids that sequence
the gases to the Oxymitter 5000, a pressure
switch that detects low calibration gas pres-
sure, and two PC boards. A terminal strip
housed within the terminal cover provides
convenient access for all user connections.
Components optional to the SPS 4000 in-
clude a reference air flowmeter and pres-
sure regulator. The reference air flowmeter
indicates the flow rate of reference air con-
tinuously flowing to the Oxymitter 5000. The
reference air pressure regulator ensures the
instrument air (reference air) flowing to the
Oxymitter 5000 is at a constant pressure [20
psi (138 kPa)]. The regulator also has a fil-
ter 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 stan-
dard. 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.
c. Operation
The SPS 4000 works in conjunction with the
Oxymitter 5000's CALIBRATION RECOM-
MENDED feature to perform an auto-
calibration. This feature automatically per-
forms a gasless calibration check every
hour on the Oxymitter 5000. If a calibration
is recommended and its contact output sig-
nal is set for "handshaking" with the se-
quencer, the Oxymitter 5000 sends a signal
to the sequencer. The sequencer automati-
cally performs a calibration upon receiving
the signal. Thus, no human interface is re-
quired for the automatic calibration to take
place.
