Sapphire Window Optical Process Probes Series 450 from Celsum Technologies - Instrumentation for rheology, strain gages, pressure transducers, load cells, temperature control, sapphire window optical probes, precision extrusion dies, and much more.

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.

Designed to fit "standard" transducer ports on materials processing plant and laboratory equipment, these probes are very useful for research and development and process monitoring applications in many industries.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.Additionally, as well as diffuse reflectance probes, we can offer you a variety of probes with transmission 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.

Key features include:

Fitted with a sealed, abrasion resistant sapphire window in the probe tip
Maximum pressure 200 bars (3,000 psi)
Maximum temperature 300°C (400°C with Vortex Cooler)
Integral 2-metre long, bifurcated fibre-optic cable assembly
with SMA905 connectors
Body manufactured in Stainless Steel 316
Certified to the specified pressures and temperatures
Helium Mass Spectrometer tested for leaks
