Introduction
OVERVIEW
Emerson Process Management offers a wide variety of RTD and
thermocouple sensors that are available alone or as complete
assemblies including connection heads, thermowells, and
extension fittings. In addition to complete assemblies, Emerson
Process Management offers heads, coupling/nipple and
union/nipple extensions, compression fittings, and thermowells.
Using this Product Data Sheet (PDS)
Use this PDS to order complete temperature sensor assemblies,
which include sensors, thermowells, extensions, and connection
heads. These options can also be ordered separately. For
example, you can order a thermowell, extension, or connection
head for use with an existing sensor. In each case it is important to
know and understand the sections of this PDS when specifying the
items.
Threaded Sensors and Assemblies
• Includes descriptions, specifications, and ordering information
for Series 58C, 68, 68Q, and 78 RTDs, and the Series 183
thermocouples.
• Includes information for ordering sensors, connection heads,
extensions, and thermowells as complete assemblies.
Calibration
• Includes characterization schedules and information for
ordering calibrated Series 68, 68Q, and 78 RTD Sensors.
• Includes information regarding the use of Callendar-Van
Dusen constants to match specific Series 68, 68Q, and 78
RTDs to Rosemount Smart Temperature Transmitters.
Mounting Accessories
• Includes descriptions, specifications, and ordering information
for temperature accessories such as thermowells, extensions,
connection heads, mounting adapters, lead wire extensions,
connectors, seals, and thermowells.
Hazardous Area Approvals
• Includes descriptions of the FM, CSA, SAA, and ATEX
approvals for sensors and connection heads.
Configuration Data Sheet
• Provides a form used for thermowell application calculations.
Series 58C, 68, 68Q, and 78 platinum RTD
temperature sensors are primarily used when high accuracy,
durability, and long-term stability are required. These sensors
conform to international standards: IEC-751, EN 60751, and BS
EN 60751. (1)
Series 58C platinum RTD temperature sensors:
• Combine an economical thin-film design with a sheath that
can be shortened to any length with tubing cutter.
Series 68Q Quick Response Sanitary RTD sensors:
• Conform to 3–A Sanitary Standards and feature product
contact surfaces designed for CIP cleaning.
Series 68 platinum RTD temperature sensors:
• Provide high performance in an economical thin-film design.
Series 78 platinum RTDs temperature sensors:
• Use a wire-wound element which allows for a broader
measurement range.
Thermocouples
Series 183 thermocouple temperature sensors conform to ASTM
E-230, and are available in types J, K, E, and T.
Series 183 thermocouple temperature sensors are available:
• grounded or ungrounded
• isolated or unisolated
• with immersion lengths from 2 to 48 inches.
