Rosemount Series 68/78 RTD Sensors come in both thin-film and wire-wound designs, offering the optimum combinations of accuracy
and durability for temperature measurements. Thermowells are offered in a wide range of materials and process connections. A
wide variety of calibration capabilities are available for increased measurement accuracy.
The Rosemount Series 68/78 RTD Sensor measures from –58 to 752°F (–50 to 400°C). Series 68 Class B,
Pt100-385 sensors are available in capsule, general purpose, and spring-loaded designs in sensor lengths
from 1 to 48 inches.
Design and construction of the Series 68 Platinum Sensors provides the optimum combination of accuracy and
durability available for temperature measurements. The construction of the sensor allows for direct immersion
in non-corrosive fluids at reasonable static pressures. For corrosive environments or many industrial applications,
these sensors are widely used with standard thermowell assemblies.
The Series 78 Sensors are intended for applications that require high accuracy, dual-elements, and/or are subjected
to high temperatures. Series 78 Platinum Resistance Temperature Sensors measure from –200 to 600 °C (–328 to 1112 °F).
These sensors are available in capsule, general-purpose, and spring-loaded in sensor (X) lengths from 1 to 68 inches.
They are also available bayonet spring-loaded style in sensor (X) lengths from 1 to 45 inches.
The wire-wound design and construction of the general-purpose Series 78 Sensor allows direct immersion in non-corrosive
fluids at reasonable static pressures. For corrosive environments and in many industrial applications, these sensors
are commonly used with standard thermowell assemblies.
