Accessories
•
Sensor parameterisation for CO
are paramaterised with specified nominal widths, standard tem-
peratures and pressures for nitrogen or carbon dioxide, then
moved to the test stand where the standard volume is tested.
•
ISO calibration points: For the purpose of basic characteristics
and accuracy, six measuring points are paramaterised with
specified nominal widths, standard temperatures and pressures,
then moved to the test stand where the standard volume is
tested.
-
ISO certificate: An ISO certificate from the manufacturer indi-
cates six measuring points with m³/min (incl. standard condi-
tions). The six ISO calibration points are required for this.
•
Measurement fitting: The measurement fitting is nickel-plated
brass and has a DN 20 female pipe clamp connection, plus a
DN 15 quick-release connection for additional measuring points
(e.g. pressure or pressure dew point).
•
Tap: The tap is nickel-plated brass and has a DN 20 female
pipe clamp connection.
•
Tapping clamp: Material: Stainless steel tapping clamp
(304/A2), Perbunan (NBR) insert, stainless steel screws and
nuts. The tapping clamp allows the sensor to be installed pre-
cisely using the drill unit without the need for welding. The cor-
responding supply line may be under pressure (normal operat-
ing conditions) when installing the tapping clamp or when
repairing/replacing the sensor.
•
Connecting cable with electrical isolator (item no. 0699 3393):
A connecting cable with an electrical isolator integrated into the
connector is available as an accessory. The cable is 5 metres
long and is used for the galvanic isolation of the sensor output
to the electronics to which it is attached. The cable is delivered
with an appropriate connector for the mass flow sensor on one
side and with open cable ends on the other side.
