Tactile pressure gauges

Last year I found a company that marketed a twinset for military use. This
had a plunger style tactile pressure gauge for use in nil vis by feel.
Unfortunately I have lost the link and cannot remember the company!



Anyone know who they may be, or have a link to anything with a similar
tactile pressure gauge please?



TIA, Mark.

There's a chance they can point you in the right direction.

There is a small 22 mm diameter monel pressure indicator used on the
latest mil spec UBA sets. The unit has a small 5 mm pin that sticks out
from a recess that you can feel when the set is full, the pin retracts
at 1/3 rd full. A similar system is used on the HEED emergency escape
device except the indicator is set to show full cylinders of up to 80%
of full pressure. Both fit to a first stage HP port.

The data sheet shows a 250MSW depth rating and in the event of a seal
failure the indicator will seal and not leak. An interesting safety
feature due to the small oxygen cylinders carried on the swimmer
delivery SDV. Not yet available, I didn't think this was public domain
yet.
The data sheet testing info shows that it passed 143,700 pressure cycles
with no leaks, then a further 252,600 cycles.
After 665,500 cycles were reached some intermittent leaks were noticed
due to slight signs of wear!! Good to know that!!
