Theory of Operation |
Bent vials start out as
a straight glass tube which is heated and then formed into a radius.
The principal of operation is that the bubble will move to the
highest point of the radius as gravity acts on the liquid inside
the vial. This is explained in more detail on our
page explaining sensitivity. The radius
can vary from 50mm to 5000mm in order to produce
vials with a range of sensitivity from 2.3° (degrees)
to 2' (minutes). There are physical limitations to what will work
effectively as a vial relating to the diameter, the
sensitivity, the bubble size and the choice of liquid. If
the glass diameter or the bubble is too small then the bubble
may stick in position. If the vial is too large and the
bubble is too small, then there will be a restricted upper
temperature limit. These are all things we have much
experience of, and as such can advise you, or design a vial to
meet your exact requirements.
We also offer Tritium illuminated levels (also known as
Betalights or Trasers) which require no power supply, have a
life of up to 20 years and enable the bubble position to be
clearly visible in the dark. Please

Inclinometers Vials, Ball and Bubble Type |
 |
|
These glass inclinometer vials are produced in our factory to the highest quality at
very competitive prices. We have many standard types available, and can also
design and produce new types to suit customers exact requirements. The two most important factors in
producing a high quality inclinometer vial are the uniformity of the bending radius, and the cleanliness
of the inside of the vial. We use advanced tooling and
machinery to ensure the radius is accurate and repeatable, and have a special
cleaning process to ensure the vials are free from particles and dust.
This is very important especially with the ball type vials where a small
dust particle can interrupt the smooth movement of the ball. Please

for more information or with details of your application. |
