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. Preevacuation 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

1.2. Installation

Independent leak test station:

1. Connect TGF10 to Leak Detector Sensistor ISH2000.

2. Connect compressed air to compressed air port.

3. Connect Tracer gas port to gas bottle.

4. Connect a large hose (∅ 12 mm. or more) to the exhaust port. Remote end of hose should be placed in a ventilation stud carrying out of the building.

NOTE: Maximum length for a 12 mm hose is 5m. Use bigger diameter if longer hose is needed. Too high resistance in the exhaust hose will severely reduce capacity of venturi pump.

5. Connect Test port to test object or fixture.

Adding leak detection equipment to an existing pressure decay station:

1 - 4 As above.

5 Connect test port to exhaust port of pressure decay tester.

NOTE. Test port of TGF10 is open to exhaust in standby mode. This means that the pressure decay instrument can operate normally with the TGF10 instrument connected.

1.3. Operation

Leak Detection Sequence:

1) Press the start button.

a) The “Evac” diode comes on and the test object is evacuated.

Pre fill evacuating time is set and adjusted by a timer in Sensistor ISH2000.

b) The “Fill” diode comes on and the “Evac” diode goes off.

Note: The “Evac” diode goes off shortly after the “Fill” diode has come on. Test object is now filled with tracer gas. Filling pressure is controlled by the gas bottle regulator.

2) Search and locate leak(s).

3) Press stop button.

a) The “Evac” diode comes on and the test object is evacuated. b) After test evacuation time is set by a timer in Sensistor

ISH2000.

c) Evacuation stops and Test object is refilled with air to

atmospheric pressure
