Thermistor Strings incorporate interchangeable, curve tracking, negative temperature coefficient (NTC) thermistors. As the Thermistors are Resistance-Temperature curve matched over selected temperature ranges, this permits the use of multiple sensors with a single readout or data logger, eliminating costly calibration procedures.
RST’s Thermistor Strings are custom manufactured to user specifications for cable length, thermistor number and location on the string. Resistance to water ingress is ensured by a triple encapsulation procedure and is rated to 3.5MPa. The standard cable employed is a heavy-duty, direct burial-rated 22-24 AWG gauge water-blocked instrumentation cable.

RST’s DT Series and RSTAR Affinity Data Loggers or FlexDAQ Data Loggers can be used to monitor one or multiple Thermistor Strings.
