Product Highlights
  • Everything great about the standard DTC.
  • Up to 6ft (1.8m) length
  • Armored or standard cable lead.
  • Unbelievably durable. Survives underneath pavements, near-shore sea ice, submersible.
  • Plug & Play with all beadedstream connectivity devices


Use the rigid probe for collecting temperature data with sensor spacing as close as every 2.5cm (1 inch). Rigid probes are solid, waterproof, and resistant to frost jacking forces that can overstress any cable solution. It is great for a variety of applications from road weather information systems (RWIS) to near-shore sea ice monitoring to pond and streambed temperature monitoring. The probe length is customizable to up to six feet (1.8m). A “flying lead” sensor for precise installation in pavement sections can be added if desired. beadedstream’s rigid probe merges novel digital technology with a proven temperature node configuration to not only improve data quality, but also promote data continuity for a well-established monitoring program.


Polyurethane cable jacket stays flexible below -40 C/F ensuring handling in arctic conditions will not damage cable.

1-wire technology permits over 100 sensors per single cable while remaining lightweight for field technicians.

Integrated aramid fiber increases torsional strength far beyond copper wiring and urethane jacket for extended product life and reduced long-term cost.

All-digital temperature conversion occurs at the sensor for better accuracy on your mission critical projects.

Common 1-wire signal conversion adapts easily to other communication protocols (RS232, TTL, RS485, etc) for easy integration with logger installations.

Unique water-clear encasement molding allows ultra-fine sensor spacing for precision temperature gradients.
