Digital Temperature Cable (DTC)

Product Highlights
  • Digital thermistor string with up to 125 sensors.
  • Custom comes standard, put sensors where you want them, vary every sensor spacing if you want.
  • Plug & Play with more connectivity devices.
  • Resilient and repairable, just three conductors.
  • Go the distance, up to 750m (2460 feet), call for longer configurations.


beadedstream Digital Temperature Cables (DTC)s increase the speed and ease of obtaining temperature data for your environmental or infrastructure application. The thermistor cable interface directly with beadedstream’s ultra-low power temperature data loggers. Since our thermistor strings are fully digital, connecting to most data loggers or existing networks is easy using our low-cost interface.


Get accurate, highly resolved measurements for air, soil, or water temperature. Down a hole, on a mountainside, under a road, through a dam, in a lake, use beadedstream cables wherever you need reliable temperature measurement.


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

1-wire technology permits up to 125 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.
