Rosemount Models 244EH and 244ER PC-Programmable Temperature Transmitters

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).
