RST Instruments’ custom-manufactured thermistor strings provide temperature monitoring that is both reliable and easy to implement. Single-point and multipoint strings with short or extended lengths are available. The temperature points are thermistors that are precision-matched for interchangeability. This permits the use of multiple sensors with a single readout or data logger, eliminating costly calibration procedures.
Our Thermistors can be used anywhere you need near real-time information about the temperature conditions of your infrastructure. Their applications include baseline ground temperature monitoring for mining projects, permafrost studies, ocean temperature monitoring, as well as monitoring concrete curing temperature during mass concrete placement and water seepage in earthfill and tailings dams.
The Thermistors you use need to be tough enough to withstand the conditions they’re meant to monitor. RST’s Thermistor strings are triple encapsulated in direct-burial-rated 22-24 gauge water-blocked instrumentation cable for protection against water ingress and physical damage. With operating temperatures between -40°C and +75°C and a stability of ±0.01°C or better for 100 months at 0°C, extreme environments won’t limit where you use our thermistors.
An accurate history of temperature can be recorded using an RSTAR Affinity Data Logger together with an RSTAR Affinity Gateway for a fully automated system. Trigger alarms can then be set within the RSTAR Affinity Data Platform.
I’m very happy with the quality of the instrumentation and technical support from RST, as always. They worked with us from the initial stages of the project to ensure that we were fully prepared and equipped to use the RSTAR network for the first time. They delivered everything within the tight project time frame to ensure that there were no delays on site, and the submersible tilt meters looked like new even after over twelve months of being submerged in Thames water!
