A source of instrument air is optional at the Hazardous Area Oxymitter 4000 for reference
air use. Since the unit can be equipped with an in-place calibration feature, provisions can
be made to permanently connect calibration gas bottles to the Hazardous Area
Oxymitter 4000.
If the calibration gas bottles will be permanently connected, a check valve is required
next to the calibration fittings on the integral electronics.
This check valve is to prevent breathing of the calibration gas line and subsequent flue
gas condensation and corrosion.
The check valve is in addition to the stop valve in the calibration gas kit and solenoid
valves in the IMPS 4000 or SPS 4001B.
NOTE
The integral electronics is rated NEMA 4X (IP66) and is capable of operation at
temperatures up to 85° C (185 F).
The optional LOI is also rated for operation at temperatures up to 85°C (185° F) .The
infrared keypad functionality will deg rade at temperatures above 70° C (158° F).
Retain the original packaging for the Hazardous Area Oxymitter 4000, in case the
components are to be shipped to another site. This packaging is designed to protect
the product.
If using an IMPS 4000 with a Hazardous Area Oxymitter 4000, the IMPS 4000 sequencer
must be installed in a non-hazardous, explosive-free environment.
For further IMPS 4000 information, refer to the IMPS 4000 Intelligent Multiprobe Test Gas
Sequencer Instruction Manual.
If using an SPS 4001B with a Hazardous Area Oxymitter 4000, the SPS 4001B sequencer
must be installed in a non-hazardous, explosive-free environment.
For further SPS 4001B information, refer to the SPS 4001B Single Probe Autocalibration
Sequencer Instruction Manual.
The display, Figure 1-8, provides a simple, economical means to obtain accurate, reliable,
and remote indication of important process variables. This display operates on the 4-20
mA line from the Hazardous Area Oxymitter 4000.
Refer to Model 751 remote powered loop LCD manual for calibration and wiring.
