SST SINGLE-SIDED TRANSMISSION PROCESS PROBE

Single-Sided Transmission Process Probe

Gold Brazed Transmission SST Probe for Process Sampling

Our GUIDED WAVE™ Single-Sided Transmission (SST) Probe is our most popular fiber optic probe. On the market for over 3 decades, it has been the most widely copied probe design in the industry. Rugged and reliable, it’s ideal for continuous process monitoring applications. Easily installed in a pipe or reactor through a single access port, the SST Probe is compatible with any Guided Wave analyzer and many other analyzer brands. Optional accessories make it easy to adapt the SST Probe to different kinds of process installations.

Unique Insertion Probe Design

The GUIDED WAVE Single-Sided Transmission (SST) Probe houses incoming and outgoing optical-fibers side-by-side in a single 3/4-inch, or 1-inch diameter stainless steel body. This unique, compact design (U.S. Patent #6,043,895) means true transmission which translates to more signal, less noise, better measurements.

Process-Resistant Probe Body Construction

The GUIDED WAVE Single-Sided Transmission (SST) Probe is designed to withstand harsh process conditions. The body of the probe is built from 316L stainless steel or, by special order, other corrosion resistant materials. The SST Probe’s sapphire optical windows are sealed to the probe body with proprietary gold alloy brazing. These materials are unaffected by most hydrocarbons and polymers. For extremely corrosive process streams, use the O-Ring SST Probe instead. Additionally, our special construction techniques also make the probe insensitive to most process pipe vibrations.

Exceptional Light Transmission

Like our other GUIDED WAVE optical probes, the SST Probe provides exceptional optical performance. Typically, peak transmission exceeds 40%. That means more signal, lower measurement noise, and lower limits of detection. Of course, the SST Probe’s optics are permanently aligned at the factory. There’s no need for optical adjustments at the time of installation, nor ever any chance for misalignment or varying pathlengths.

Compatible with All of Our Guided Wave Analyzers and Many Other Analyzer Brands

The probe, or sample interface, is a crucial component of a complete analyzer system. For optimal performance, the probe must be ‘’optically matched’’ with the spectrometer and with the optical fiber that transmits the spectral signal. The SST Probe (and each of our other GUIDED WAVE optical probes) is matched to our analyzers and fiber to achieve the highest possible performance. Our probes also work with many other brands of fiber optic analyzers, according to fiber diameter and spectral range.
