Leak Testing At the Limit
The S9 from Nolek has taken air leak test technology to the limit by combining the most sensitive pressure differential leak test valving with the most advanced front-end interface available.
The latest unit from Nolek/TQC is the result of a two-year programme to develop the most flexible combined leak test instrument on the market The S9 has an architecture that enables up to five functional valve modules to be connected to a single front-end interface, allowing simultaneous testing of five volumes

Leak test instrument reckoned to be most flexible
Combining the most sensitive pressure differential leak test valving with the most advanced front-end interface available has resulted in most flexible combined leak test instrument on the market.
Assembly technology experience to be exchanged
November 6th and 7th sees the next meeting of Assembly-Net, a European funded project established in order to share and exchange the latest developments in assembly system technology.
Each module has an electronic pressure regulator for setting of the test pressure automatically from the instrument.
There are three types of valve module to cover a range of pressures.
These are: Vacuum pressure differential module Positive pressure differential module Flow module The front-end interface consists of a graphic display and function keypad from which all of the instrument parameters and results can be obtained.

Mini brochures cover handling and leak testing
For concentrated marketing in two niche areas, "Assembly and Testing of Automotive Panels and Components" and " Casting Leak Test Machines" 4-page mini colour brochures are now available.
When handling means assembly as well
Due to the increasing trend towards supplying modules, or sub-assemblies, as well as plastics components, TQC has supplied localised assembly systems for use by plastics moulders.
The front end interface also has facility for direct control of all parameters and recording of results straight into a PC.
In addition to the facilities for simultaneous testing provided by the multiple valve modules, the front-end interface allows consecutive testing of different volumes and/or tests at different pressures.
Within the instrument's memory can be stored up to 99 different sets of leak testing parameters.
The instrument can therefore be used to test as follows: Multiple parts, simultaneous testing on separate valve channels, using a single front-end interface.
Increased production throughput at a lower cost with a single instrument.
A single part, simultaneous testing multiple internal volumes, using a single front-end interface.
Allowing, for example, consecutive leak testing of an engine oil gallery, water gallery and the inter-stream leakage between the oil and water galleries.
Increased production throughput at a lower cost with a single instrument.
A single part, consecutive testing of a single volume that should behave differently at different pressures.
For example testing an engine fuel rail with differing pressure regulators to ensure that the correct regulator has been assembled and that each regulator correctly opens.
Lower cost with a single instrument.
A variety of parts with different test parameters that can be changed with a simple selection of a new program.
The electronic pressure regulator will automatically set the new test pressure.
Lower cost with a single instrument.
High speed leak testing.
The unit has been designed with "zero offset compensation" and "quick stop" features to make the S9 the fastest high quality leak tester on the market.
Increased production throughput at a lower cost with a single instrument.
The new S9 instrument provides a new edge to the integrated leak and function test machines and fixtures supplied by TQC.
