Vacuum Detection/Moisture Alarm PCB set

The electronic monitoring electronics are compactly integrated into the leak detector of the enclosure, where they constantly measure the vacuum level and report its status via a multi-coloured LED that is clearly visible on the back of the enclosure. This advanced electronics has advanced temperature compensation capability so that changes in ambient or internal temperature will not cause a false signal.

From NA-70 to NA-70, the vacuum level is monitored by a multicolour LED that is clearly visible on the front of the enclosure.

From NA-70D for Canon 70D onwards, all new Nauticam DSLR and Mirrorless interchangeable lens camera housings are supplied with the electronic monitoring circuitry installed as standard. Vacuum valves are sold as optional equipment, allowing the user to customise the configuration of the housing accessory as required. The recognition of the LED colour codes is very simple. At ambient pressure, the LED flashes blue slowly. When a fixed vacuum is reached, the LED changes to a constant green, indicating system integrity. When the vacuum starts to decrease, the LED starts to flash yellow, and when water ingress is detected, the LED flashes red and the audible alarm goes off.

VACUUM VALVE (to be ordered separately)

The second component of this system is a one-way vacuum valve, which is available in different versions to support different enclosure configurations. These vacuum valves include an integrated vacuum release and redundant waterproof cap. No tools are required to open the housing after a vacuum has been created, as the vacuum is released with a simple knurled nut.

The basic valve uses a hand pump to create the vacuum, but a more advanced double activation vacuum valve is also available. The double activation valve takes a BCD low pressure inflator hose quick release and uses the cylinder pressure to create a venturi effect that pulls the vacuum. This is recommended for hulls such as Nauticam's DCES for RED EPIC and SCARLET, where the internal volume of the hull makes the use of a hand pump impractical.

"Offset"-relief valves are used when a housing has a single accessory hole, but both a vacuum valve and an electrical partition need to be installed in the same location. This will allow most homes to take advantage of this valuable tool.

All vacuum valves also include a hand pump and a wrench tool to install the valves.

THE CONCLUSION

This new system is the most advanced Integritätsprüf system on the market and the only one with integrated leak detection and temperature compensation. With its intuitive multi-colour LED status codes, the underwater photographer can now be sure with a simple glance that the waterproof integrity of the housing is assured.
