Damping

4-20 mA HART

Analog output response to a step input change is user-enterable

from 0.0 to 60 seconds for one time constant. This software

damping is in addition to sensor module response time.

Physical specifications

Material selection

Emerson provides a variety of Rosemount products with various

product options and configurations including materials of

construction that can be expected to perform well in a wide

range of applications. The Rosemount product information

presented is intended as a guide for the purchaser to make an

appropriate selection for the application. It is the purchaser’s

sole responsibility to make a careful analysis of all process

parameters (such as all chemical components, temperature,

pressure, flow rate, abrasives, contaminants, etc.), when

specifying product materials, options, and components for the

particular application. Emerson Process Management is not in a

position to evaluate or guarantee the compatibility of the

process fluid or other process parameters with the product

options, configuration, or materials of construction selected.
