Thermo Tec Resistance Temperature Detectors (RTDs) are high-precision temperature sensors engineered for reliable and accurate measurement in industrial, commercial, and OEM applications. Based on the principle that a material's electrical resistance varies predictably with temperature, RTDs provide excellent accuracy, long-term stability, and repeatable performance.

The product range includes RTDs with Platinum (Pt), Nickel (Ni), Copper (Cu), PTC, and NTC elements. Sensor constructions are available in industrial assemblies with terminal heads, mineral-insulated (MI) probes, cable probes, sanitary sensors, and surface-mounted designs.
