Custom Engineering — Pillar Hub for Bespoke Sample Probe Design
Pillar for custom-engineered sample probe assemblies: non-standard geometries, exotic materials, special angles, heated probes, retractable designs, and bespoke flange-and-valve combinations.
When Stock Won't Do
A stock sample probe is a starting point. Real installations bend that starting point with non-standard angles, exotic alloys, heated jackets, retractable mechanisms, and specialty tip geometries. This pillar gathers every blog, product, and configurator option that supports custom-engineered probe assemblies.
Custom Dimensions
The configurator accepts arbitrary lengths, ODs, wall thicknesses, and insertion angles within the validated envelope. When a request falls outside the envelope, our engineering team performs a manual wake frequency analysis and a Barlow's hoop-stress check before quoting.
Custom Geometries
- Stepped probes — different OD on the wetted vs. inserted sections
- Tapered tips — for low-drag insertion through dense particulate streams
- Dual-bore probes — simultaneous sample + purge
- Crown / chisel / pencil tips — for piercing or surface contact
- Cut sides and angles — see probe end types
Custom Materials
Beyond the stock material list:
- Tantalum & Zirconium for hot concentrated acids
- Alloy 20 / Carpenter 20 for sulfuric acid service
- 6Mo super-austenitics for chloride-rich seawater
- Nickel 200 for caustic
- Polymer linings (PFA, FEP, ETFE)
Heated and Retractable Variants
- Heated probes keep the tip above the dew point of hydrocarbon streams to prevent wax and asphaltene buildup.
- Retractable probes allow extraction without process shutdown via packing-gland or ball-valve isolation.
Custom Sealing & Connection
Default is a Conax PG packing gland. Custom builds support:
- Special gland body (counterbore, integral O-ring, dual sealant)
- Flanged or threaded connections
- ANSI / ASME / DIN / JIS flange standards
- Hub-style connections for bolt-down installations

Configure or Engineer
Most requests can be quoted directly through the Configurator. For requirements that exceed its envelope, the configurator's review step generates a structured spec sheet our engineering team uses as the starting point of a custom quote.
