Gas sampling and gas conditioning technology 2-2.1-ME
10 APPLICATIONS
The PSP4000-H... gas sample probes are used for extraction of gases from dust loaded, high-
temperature or humid processes.
Due to its compact design and low weight, the device is envisaged particularly for mobile uses. The
basic probe including the compact sample adapter with variable probe tube lengths enable rapid and
centric gas sampling from, for example, exhaust gas pipes with diameters of between 150 mm and
600 mm.
A probe tube with a fixed length of 1 meter extends the range of potential applications.
With version PSP4000-H/C/T, parallel to gas sampling it is also possible to measure the process
temperature at the end of the probe tube using an integrated thermo-couple sensor.
To avoid cooling and condensation of sample gas in the extraction area, a heated sample probe tube
SP34-H.. is available.
Appropriate accessories are available for mounting the probes directly at the flange or threaded
sleeve-mounting brackets.
The specially designed, electrically-heated sample lines PSP 4M4/6 or PSP-W4M4/6 with reduced
outer diameter can be connected to the PSP4000-H... for transporting gas to the gas sample
conditioning system.
N O T E !
The max. length of heated sample lines for PSS-5 gas conditioning systems
with integrated temperature controller is 12m for 230V/50Hz resp. 6m for
115/60Hz.
If unheated sample lines are used, this should be conducted on a descending gradient to the gas
sample conditioning system.
11 DESCRIPTION
The standard version is as follows:
The stainless steel filter chamber (SS316Ti) with an integrated 2µm ceramic depth filter element is
inserted completely into an electrically heated aluminium heating jacket with a heat-insulated
protective casing.
The temperature is adjusted to + 180°C via an integrated and adjustable capillary tube thermostat.
The green control lamp glows during the heat-up phase and is extinguished when the heating element
temperature is reached. It then comes on and off as the heating element is switched on and off.
By changing the internal wiring, the sample probe can be operated at 230V 50 Hz or 115V 60 Hz. The
standard wiring is for 230V.
Electrical connection is effected at the connection socket on the probe via the power cable provided
with a 7-pin adapter jack or via an additional cable conducted within the heated sample line PSP
4M4/6 resp. PSP-W4M4/6 , also with a 7-pin adapter jack.
The adapter jack's pins are wired as follows:
Pin 3: L - Mains power line conductor.
Pin 4: N -
Mains power neutral conductor.
Pin 7: PE - Protective earthing conductor.
The probe's sample gas outlet connection has a 1/8" NPT inner thread. A temperature resistant 6 mm
tube connector is fitted gas-tight into this to connect the sample line. Once the electrically-heated
sample line PSP 4M4/6 resp. PSP-W4M4/6 has been mounted, the connection is enclosed in special
heat-conducting jaws in order to avoid temperatures falling below the required level in the critical
connection areas.
