Ice Road Temperature Cables

Product Highlights
  • Everything great about the standard Digital Temperature Cable (DTC)
  • Armored cabling between connector and first sensor for maximum animal chewing survivability
  • Developed to aid in satisfying required ground temperature criteria for off-road travel. Trusted by industry, regulatory agencies, and local stakeholders to deliver reliable conditions data
  • Plug & Play with all beadedstream connectivity devices


The Tundra DTC cable was created specifically for measuring ground temperatures of the tundra. All Tundra cables have a 90-degree sensor mold at the end of the cable followed by 4-inch spaced single sensors. Constructed of beadedstream’s Armored cable it remains flexible in the most extreme environments. This DTC comes standard with our all digital, low drift precision sensors. Lead length and number of end sensors are completely customizable to your projects specific needs.


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.

Small 11mm diameter sensor molds are robust and flexible, molded in low profile, corrosion resistant polyurethane for easy handling and extended product life.
