3. 2. 2. L - Probe with Measurement
Chamber - MK 1
|
 |
Area of application:
-
Measuring oxygen in gases
-
Indirect measurement of the carbon content in carbonizing atmospheres
-
Indirect measurement of the dew point in gases,
e. g. in the production of carrier gas for heat treatment plants
|
Function:
The L - probe is a sensor for measuring oxygen in gas atmospheres.
The probe is heated with a constant voltage. It outputs a voltage which
can be converted into oxygen, C-potential or dew point in a transmitter.
The probe is screwed into the measurement chamber and
is immersed in the gas flow. Different types of fittings are available
which are adapted to the relevant local conditions.
The measurement chamber also enables a simple connection as
a bypass for burn-off. System without gauge pressure are fitted with an
extra pump.
Only small volumes of gas are required for measuring . 10 - 20 l/h
are sufficient. A highprecision power supply unit is available as an accessory
for supplying the ceramic heating layer in the probe.
The probe can be installed anywhere. It is mounted by screwing
it in to the corresponding thead. The feed lines to the measurement
chamber must be absolutely leakproof to avoid incorrect measurement
of the very small residual values of O2.
