Multi Head Leak Detectors
Multi head leak detectors – leak detectors for very high speed. Firstly in my history in leak detection I have not been involved in building many multi-head units.
Why? Because Our Single Head Units Are So Fast
If 6LD-LP is not fast enough it is far less expensive to get a 6LD B or HP which has double the speed than build a 2 head budget machine.
A twin head 6LD B or HP is very FAST, Typically around 1.8 Times faster than a single head unit.
So if a stable 500 ML (1 PINT) bottle could be tested at 3500-4000 BPH on a single head around 7000 -7500 BPH could be tested on a twin head.
The single head machine due to bottle instability could test around 2500 BPH, with the double head it was almost double. This machine to improve handling also had a servo drive for improves ramping of the bottles as the conveyor was stopped and started.
Some ideal bottles on a twin head could be tested at 8000-10,000 per hour.
This type of unit can replace the need for small rotary leak testers (4-6 head).
Multi head machines are generally more time consuming to set up and samples are required to ensure the best solution is offered.
Bottles with poor stability will have the slowest test rate on the machine.
A variety of technical solutions are available for high speed testing.
