System Description
Permeation Oven (Optional)
Thermo Scientific 146iQ Instruction Manual 8-3
The gas flow is held constant by a pressure regulator followed by a
capillary, and is actively measured by the flow pressure DMC.
The optional ozonator lamp power supply generates high voltage AC and
contains heater control circuits for the ozonator lamp.
The 146iQ can be configured with an optional permeation oven for
generating stable concentrations of calibration gases that can then be
diluted down to the user-desired concentrations and flows with the help of
the Zero Air Mass Flow Controller. The permeation oven is configured as a
DMC module with self-contained temperature measurements and heater
controls. For more information, see “
Permeation Oven ” as described in
Chapter 9, “ Optional Equipment ”.
The common electronics contain the core computational and power
routing hardware for the 146iQ, and is replicated throughout other iQ
series products (
Figure 8–1 ). It also contains the front panel display, the
USB ports, the Ethernet port, and the optional I/O interfaces (RS-485,
analog, and digital).
Figure 8–2 shows the PCBA interconnect structure for the 146iQ,
including options. The modular design of the instrument is conveyed in
the architecture. Brief descriptions of the specific PCBAs follow.
