Series 78 RTD Series 78 sensors are intended for special applications that require high
temperature, compensation loop, or dual element sensors.
Rosemount Series 78 RTD Temperature Sensors are used for
measurements from –328 to 1220 °F (–200 to 660 °C). Series 78 sensors
are available in capsule, general purpose, and spring-loaded designs in
J
lengths from 1 to 24 inches.
Table 7-3 shows the interchangeability of the Series 78 RTD.

Interchangeability.
Platinum Element and
Lead Wire Configurations Single-element, high temperature sensors have four lead wires and
may be used in 2-, 3-, and 4-wire signal conditioning systems.
NOTE
Series 68 and 78 sensors conform to international standards: IEC-751
Class B; DIN 43760; and BS 1904 Grade II. For additional information
on temperature sensor assemblies, refer to Rosemount Product Data
Sheet PDS 2654.
NOTE
Table 7-4 summarizes Series 68 and 78 Sensors that are most likely to
be used with the Model 3095FT. The sensor assembly code shown in
Table 7-4 combines sensor type, an FM or CSA approved connection
head, and no extension.
