Our
rugged right-angled sapphire window optical probe is especially designed
for use on injection moulding machine nozzles, where the nozzle has to
advance for each shot through an 8" (200 mm) diameter hole in the
front platen in order to connect with the mould gate.
For the Production Online project at Exeter Advanced Technologies
in Exeter University, two of these probes are being used as an opposed
pair for transmission NIR studies of polymer melts. The technique allows
in-line measurements for each moulding shot; the NIR data can be correlated
with such parameters as moisture and additive content, Melt Flow Index
(MFI), and can give real-time alarms of changes in the material properties
so that prompt action can be taken, saving materials, time and energy
and providing a powerful SCADA quality control tool.
As well as injection moulders, of course, the probes can be used to monitor
other industrial processes such as mixers, extruders, reactors, pipelines,
etc. Additionally, as well as transmission probes, we can offer you a
variety of probes with diffuse reflectance optics, and test cells for
liquids and gases.
We can supply adaptors to allow these probes (and others!) to be
fitted to your equipment: let us have a sketch of your requirements and
we'll send you a price. We can also supply high-temperature, armoured
fibre-optic cables to connect our probes to your instruments.
