1.2 About the transmitter

Micro Motion rack-mount transmitters have enhanced EMI immunity that

complies with EMC directive 89/336/EEC and low-voltage directive

73/23/EEC, when properly installed in accordance with the guidelines

and instructions in this manual.

The Model RFT9739 transmitter is a microprocessor-based transmitter

for fluid process measurement. The transmitter works with Micro Motion

sensors to measure mass or volume flow, density, and temperature.

The rack-mount RFT9739 is for control-room mounting. The housing is a

1/3 rack cassette for 19-inch enclosure-dense packaging. Components

of the transmitter are shown in

Figure 1-1

, page 2.

liquid crystal display (LCD). Scroll and Reset buttons enable the user to

perform the following operations. Use of the display is described in

Section 6.2

, page 60.
