Chaînes de thermistors

Thermistor Strings are curve matched to desired temperature tolerance over selected temperature ranges. This permits the use of multiple sensors with a single readout or data logger, eliminating costly calibration procedures. Environmentally hardened to provide accurate and reliable long-term measurements under demanding geotechnical conditions. The strings incorporate interchangeable, curve tracking, negative temperature coefficient (NTC) thermistors. […]

Thermistor Strings are curve matched to desired temperature tolerance over selected temperature ranges. This permits the use of multiple sensors with a single readout or data logger, eliminating costly calibration procedures.

Environmentally hardened to provide accurate and reliable long-term measurements under demanding geotechnical conditions. The strings incorporate interchangeable, curve tracking, negative temperature coefficient (NTC) thermistors. As the thermistors are curve matched to desired temperature ranges, this permits the use of multiple sensors with a single readout or data logger, eliminating costly calibration procedures.

Custom manufactured to user specifications: cable length, thermistor number, accuracy, and location on the string. Resistance to the ingress of water is insured by a triple encapsulation procedure. Standard cable employed is a heavy duty, direct burial rated 22 gauge water blocked instrumentation cable.

  • High reliability, ensured by triple encapsulation
  • Precision matched, interchangeable thermistors
  • Pre-assembled to specific length and spacing
  • Heavy duty, direct burial cable standard
