Flow Rate:
• 5-30 L/min for window purge
• 2 L/min for validation, calibration and optical
purge
SIL Assessment:
The TDLS200 has a FMEDA assessment by exida and is
classified as a Type B1 device in compliance with the following
standards; IEC 61508 or EN 954-1. Functional Safety of Electrical/
electronic/programmable electronic related systems; SIL 1
capability for single device.
* The TDLS200 is not SIL certified as standard; to be certified the unit
must be specified and designed from the beginning to meet all SIL
specifications.
Basic System Configuration
The TruePeak can be installed in a number of ways depending on
process requirements. The most typical installation types are shown
below, however other installation methods are possible, please contact
Yokogawa with your application details.
Cross Stack/Pipe Configuration
• Measures directly across process pipe or vessel
• Typically has nitrogen or other purge gas protecting
process windows
• Span Validation via serial flow cell (see Operation Specifications).
• Full calibration requires removal from process
• May require pressure and temperature inputs
(Application Dependant)
• Multiple methods to increase Optical Path Length (OPL) if needed
• 5 meter interconnection cable standard
Close Coupled Extractive / Bypass Configuration*
• Measures across a section of pipe where process flow
is directed
• The measurement section can be isolated from process flow for full
calibration/validation, zero and span
• Process pressure and temperature can be controlled
or the analyzer may require pressure and temperature inputs
(Application Dependant)
• Length of measurement section dependant on accuracy requirements
and process conditions
Extractive Configuration*
• Sample is fully extracted from process
(and may be conditioned before measurement).
• Flow cells are available with ability to purge in front of windows
(balanced flow cell) if required.
• Process pressure and temperature can be controlled
or the analyzer may require pressure and temperature inputs
(Application Dependant)
• Length of flow cell dependant on accuracy requirements
and process conditions
