Emerson 0068L21A30A060T20E6 Temperature Sensor

Emerson's Rosemount 0068L21A30A060T20E6 Temperature Sensor is a platinum RTD temperature sensor in the Rosemount 68 family, designed for industrial process temperature measurement without a thermowell. In Emerson's part-numbering scheme, 0068 identifies a platinum temperature sensor without thermowell; L denotes an aluminum connection head with six terminals and a flat, unpainted cover; 21 indicates a spring-loaded style, with the remaining characters encoding length, cover options, and extension length. Pt RTD Rosemount 68 sensors are used with Rosemount temperature instrumentation and offer stable, repeatable measurements across industrial environments; typical accuracy for these platinum elements has been documented as about ±0.3 °C at 0 °C. Common industrial applications include chemical processing, refining, and other facilities where robust RTD sensing is preferred over thermocouples.
