Our resistance temperature detectors (RTDs) function on the principal that a material’s electrical resistance changes with temperature. This positive resistance-temperature relationship holds true within extreme temperature ranges over extended periods of time. With knowledge of this relationship, an accurate measurement of temperature can be derived from the resistance value of an RTD.
IST’s temperature product line includes platinum and nickel RTDs, and temperature sensor ICs. Platinum and nickel sensors are both resistance temperature detectors with a variety of temperature ranges, extension types, and nominal resistances. While platinum can withstand extreme temperatures from -200°C to +1000°C, nickel has higher resolution within a smaller temperature range. We also offer custom RTDs in both platinum and nickel with user specified values for TCR, nominal resistance, etc. TSic sensors are semiconductor temperature sensors that feature highly accurate measurement within a limited temperature range. They are ideal for mobile applications due to their low power consumption.
