Mineral Insulated RTD Sensors

Resistance temperature detectors (RTD’s) are wire wound or thin film temperature sensing devices consisting of a wire coil or deposited film of pure metal (usually platinum). The elements resistance increases with temperature in a known and repeatable manner, therefore exhibiting excellent accuracy over a wide temperature range. The platinum RTD produces a more linear curve than thermocouples and are used when accuracy of output is important, as they are less sensitive to temperature changes than thermocouples.

Advantages of RTD's include: stable output for long period of time, ease of recalibration, and accurate readings over relatively narrow temperature spans.

A mineral insulated constructed RTD assembly ensures a temperature sensing device that is both rigid and robust, giving it mechanical strength along with high vibration endurance.
