SPS 4000 (OPTIONAL). The SPS 4000 Single Probe
Autocalibration Sequencer provides the capability of
performing automatic, timed or on demand, calibra-
tions of a single Oxymitter 4000 without sending a
technician to the installation site.
a.
Mounting. The SPS 4000 can be mounted either
directly to an Oxymitter 4000 or at a remote loca-
tion if space is limited. In addition, the integrally
mounted SPS 4000 can be configured for a hori-
zontally or vertically mounted Oxymitter 4000
(Figure 2-2). The information in this instruction
bulletin will cover the integrally mounted units
only. For information on remote mounted units, re-
fer to the SPS 4000 Single Probe Autocalibration
Sequencer Instruction Bulletin.
b.
Components (Figure 1-5). The SPS 4000 con-
sists of a manifold and a calibration gas flowme-
ter. The manifold 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 con-
venient access for all user connections.
