Analyzer design

LS4000, LS4060 DIODE LASER ANALYZERS | OI/LS4000/O2-EN REV. A 11
The analyzer consists of a transmitter unit and a receiver unit, which are in-
stalled opposite one another on a process line or stack and connected to each
other via a junction box.
The following components are connected to the junction box:
Transmitter unit and receiver unit
T/P probe(s) for dynamic temperature and pressure correction (depending
on application)
Power supply
Sensors for analog and digital outputs
Depending on design: External power supply unit (see Analyzer variants on
page 10)
A PC can be temporarily connected to the junction box for service purposes.
The LS4000 uses the optical measurement method of tunable diode laser
absorption spectroscopy (TDLAS), which is based on the fact that gases ab-
sorb light of specific wavelengths.
In this method, a configurable laser diode in the transmitter unit emits a laser
beam, which passes through the process gas and shines onto the photode-
tector in the receiver unit. The molecules of the measuring components locat-
ed in the optical path of the laser beam absorb the laser light, thereby reduc-
ing the light intensity at the receiver.
A sophisticated signal algorithm records the measured reduction in light in-
tensity and uses this value to calculate the gas concentration in accordance
with the Beer-Lambert law. The influence of temperature and pressure varia-
tions is eliminated by a dynamic automatic correction function.

present.
When the laser beam shall pass through an explosive gas mixture, an explo-
sion-proof variant of the gas analyzer with type test certificate must be used.

Tested to EN 61010-1:2010
EMC: Interference immunity Tested to EN 61326-1:2013
Inspection level: Industrial area, fulfills at
least the evaluation criteria according to
Table 2 of EN 61326-1.
EMC: Emission interference Tested to EN 61326-1:2013
Limit class B for interference field
strength and interference voltages is met.
The permissible environmental conditions for the transmitter unit
and receiver unit may differ from those of the junction box. In such
instances, compliance with the limit values of all modules must be
guaranteed by means of a suitable spatial arrangement on site.
If the junction box is set up outdoors, measures must be taken
where necessary to ensure the intended operation. This may in-
clude rain canopies, for example, or housings with an adequate IP
rating.
