Chapter 3
Wiring the Transmitter to the Sensor
3.1

Overview

This chapter describes how to connect Micro Motion Model 1700 and 2700 transmitters to a Micro
Motion sensor.
Note: If you have an integral installation, this step is not required. Continue with wiring the
transmitter outputs (Chapter 4, Chapter 5, or Chapter 6).
Wiring requirements between the sensor and transmitter depend on the installation type (see
)
Figure 2-1 .
• If you have a 4-wire remote transmitter installation, review the information on 4-wire cable in
Section 3.2, then follow the instructions in Section 3.3.
• If you have a 9-wire remote transmitter installation, review the information on 9-wire cable in
Section 3.2, then follow the instructions in Section 3.4.
• If you have a remote core processor with remote transmitter installation, review the
information on both 4-wire and 9-wire cable in Section 3.2, then follow the instructions in
Section 3.5.
3.2

Cable types

This section describes the types of 4-wire cable and 9-wire cable that can be used for wiring the
transmitter to the sensor.
3.2.1

4-wire cable

Micro Motion offers two types of 4-wire cable: shielded and armored. Both types contain shield drain
wires.
Transmitter Installation: Model 1700 and 2700 Transmitters
CAUTION
Large electromagnetic fields can interfere with
flowmeter communication signals.
Improper installation of cable or conduit can cause
measurement error or flowmeter failure. To reduce the
risk of measurement error or flowmeter failure, keep cable
or conduit away from devices such as transformers,
motors, and power lines which produce large
electromagnetic fields.
