who knows about Photomicrosensors???

[E.persia]

hi everybody
I have a project about leakage testing
we use a Photomicrosensor in a pipe and an alominioum blade between
transmitter and reciever...
but the problem is that after setting Photomicrosensor in the pipe and
using the glue signal decreases
and sensor blows
is there any water proof sensor and befor that is the water my real
problem?

thank you befor your helps!

You're not giving enough info here.
What kind of photo sensor are we talking about?
IR diode, Cadmium cell, Photo multiplier etc ?

Is the glue touching the RX/TX devices?

Have you disassembled the tube and inspected as to
the cause?

P.S.
Some glues are conductive!
