Figure 3-16: T200M Internal Pneumatic Block Diagram - Standard Configuration
Note Pneumatic Diagrams do not reflect the physical layout of the instrument.
The most significant differences between the T200H and T200M versions in regards to
pneumatic flow are:
A bypass line leading directly from the particulate filter to the exhaust manifold is
present on the T200H, but not in the T200M.
The diameter of the critical flow orifice controlling the gas flow into the sample
chamber is smaller and therefore the flow rate of sample gas through the instrument
is lower.
