TRACER GAS FILLER TGF10
1.1.

General

Tracer Gas Filler TGF10 evacuates and fills an
object subject to leak detection.TGF10 is an
accessory to Hydrogen Leak Detector Sensistor
ISH2000 and can be used together with most of
INFICON probes.
Evacuation and filling is time controlled by the
APC system in the Sensistor ISH2000 Leak
Detector.
TGF10 feature:
The air in the test object is pumped out by a
built in venturi pump before tracer gas is
injected. This is done to make sure that the
tracer gas completely fills the test object. Pre-
evacuation is particularly important on very
long objects e.g. pipes or heat exchangers.
Sequence:
1) Press the start button.
a) Test object is evacuated.
The "Pre Evac Time" is set and adjusted
by a timer in Sensistor ISH2000.
NOTE! Setting a timer equal to zero
(0,0) means that entire line is skipped,
and outputs are not changed.
b) Evacuation ends.
c) Test object is filled with tracer gas.
Filling pressure is controlled by the
gasbottle regulator.
(Test object is ready for leak detection).
2) Press stop button.
a) Test object is evacuated.
The "Post Evac Time" is set by a timer in
Sensistor ISH2000.
b) Evacuation stops and test object is
refilled with air to atmospheric pressure
