INSTALLATION

UM344-2

4.2 ENVIRONMENTAL CONSIDERATIONS

Many industrial processes create severe environmental conditions. The conditions at each transmitter location must be within the specifications stated in Section 8.3.5.

The Transmitter is designed to perform in harsh conditions, however, it is prudent to locate a Transmitter to minimize the effects of heat, vibration, shock, and electrical interference.

CAUTION

Exceeding the specified operating temperature limits can adversely affect performance and may cause damage.

4.3 INSTALLATION CONSIDERATIONS

Sections 4.3.1 and 4.3.2 outline basic considerations needed to achieve a successful mechanical/electrical installation. The remaining sections then provide detailed pre-installation information.

4.3.1 Mechanical

∙Select the sensor input: thermocouple, millivolt, RTD, or resistance. Refer to Section 8.2 for sensor accessories.

∙Determine if an optional digital meter for local monitoring of transmitter output is required. Refer to Section 8.1 for model designation or 8.2 for accessory part numbers.

∙Determine physical mounting of Transmitter. Consider:

∙Using supplied bracket for pipe or wall mounting. Refer to Sections 4.4.1 and 4.4.2.

∙Transmitter-to-process mounting. Refer to Section 4.4.3.

∙Clearance for installation and maintenance and for reading the optional digital meter. Refer to Figure 8-3.

∙Need to rotate optional digital meter for viewing ease. Refer to Section 4.4.4.

Refer to Figure 8-3 for transmitter dimensions and the figures in Section 4.4 for typical mechanical installations. Refer to Section 8.3 for mechanical and environmental specifications.

ŸDetermine if an explosion-proof or intrinsically safe installation is required. Refer to Transmitter nameplate for electrical classifications and Sections 8.1, 8.3, and 4.6.

An intrinsically safe installation requires user-supplied intrinsic safety barriers that must be installed in accordance with barrier manufacturer's instructions for the specific barriers used.

Transmitter certification is based on the "Entity" concept in which the user selects barriers that permit the system to meet the entity parameters.
