We
supply a range of standard and tailor-made precision optical probes to
allow you to make direct on-line measurements of your material during
processes including extruders, reactors and injection moulding machines
using, for example, Near Infra-Red (NIR) spectroscopy. Key features are:
Fitted with a sealed, abrasion resistant sapphire window in the probe
tip
Polymer
Transmission Probe allows pressures to 700 bars (10,000 psi), temperature
to 420°C
Injection
Moulding Probe will acheve pressure of 2,100 bars (30,000 psi), temperatures
to 300°C
Temperatures
to 300°C as standard; to 400°C with optional vortex cooler with
some units
Pressures
to 200 bars (3,000 psi) for "standard" probes
600
micron, ultra-low-OH silica fibre with a 0.22 NA
SMA
905 compatible connectors (others available)
Bodies
manufactured in Stainless Steel 316L - other materials available
Certified
to the specified pressures and temperatures
Helium
Mass Spectrometer tested for leaks.
Our
Materials
Processing Transmission Probe has been designed specifically
with extrusion applications in mind. It fits a "standard"
transducer port, will take pressures to 700 bar (10,000 psi) and temperatures
to 420°C. The probe can be fitted with a single optical fibre
or a bundle, and may be supplied with your choice of optical connector.

Our
Right-Angled
Injection Moulding Transmission Probe
was designed especially for the rugged demands of moulding,
and for the spatial constraints of a nozzle-mounted probe having
to pass through the bolster plate of the moulding machine. This
probe will permit measurements up to 300°C at pressures to 2,100
bars (30,000 psi), is made from 17-4PH stainless steel, is fixed
into a pocket on the nozzle by a rotating "jam nut", and
is fitted with an SMA 905 optical connector. This probe is being
used to good effect in the Production
OnLine Project at Exeter Advanced Technologies in Exeter
University.

| Series
350 Single
Fibre Transmission Probes
allow a "standard" 1/2"-20-UNF transducer port to be
used for optical studies. Used in pairs, the collimated beam of this
probe provides excellent transmission characteristics. The maximum
pressure is 200 bars (3000 psi), and maximum temperature is 300°C,
with 400°C possible with an optional vortex cooler. Stem
lengths of 153 mm (6") and 203mm (8") are available as standard,
but we are always happy to quote for non-standard sizes. |

Series
450 Diffuse Reflectance Probes allow
a single 1/2"-20-UNF transducer port to be used to measure
your material properties in process and test. The probes are supplied
complete with an integral 2 metre bifurcated fibre optic cable assembly,
both
transmitting and receiving branches fitted with SMA905 connectors.
Maximum pressure is 200 bars (3,000 psi), and maximum temperature
300°C (400°C with vortex cooler). Stem lengths of 153 mm
(6") and 203 mm (8") are available as standard, others
to order.

We
can supply a range of precision-engineered adaptors to allow
our probes to be fitted to your process line or lab instrument,
and to suit the path length required by your optical instruments.
Let us have details
of your needs, and we will provide prices. We can also supply
high-temperature, armoured fibre-optic cables to connect
our probes to your instruments.
