Rosemount Models 244EH and 244ER PC-Programmable Temperature Transmitters
A-8
Ordering Flameproof and
Explosion-proof Approvals
for Temperature
Assemblies
Both flameproof and explosion-proof protection depend on the enclosure
type. Compliance with flameproof and explosion-proof approvals
requires an appropriately approved assembly, including the sensor. The
Model 244EH requires an appropriate enclosure for approved use in
locations requiring flameproof or explosion-proof installations.
Orders that include enclosure options J5 or J6 must be ordered from
the Model 244EH ordering information table.
When ordering a complete DIN style assembly, select the appropriate
connection head from Volume 2 of the Rosemount Temperature Sensors
and Accessories PDS (document number 00813-0101-2654).
