A.4 Physical specifications

The physical specifications of the transmitter include:

•Housing

•Mounting

•Interface/display (optional)

•Weight

•Dimensions

A.4.1 Housing

NEMA 4X (IP67) epoxy painted cast aluminum housing.

Terminal compartment contains output terminals, power terminals and service-port terminals. The output terminals are physically separated from the power- and service-port terminals.

•The electronics compartment contains all electronics and the standard display.

•The sensor compartment contains the wiring terminals for connection to the core processor on the sensor.

Screw-terminal on housing for chassis ground.

Cable gland entrances are either 1/2″–14 NPT or M20 × 1.5 female conduit ports.

A.4.2 Mounting

Model 1700/2700 transmitters are available integrally mounted to some Micro Motion sensors, or in two remote-mount configurations.

•Remote-mount transmitters include a mounting bracket, and require 4-wire or 9-wire signal cables between the sensor and the transmitter. Maximum distance from other flowmeter components depends on the installation type and cable type, as described in Table A-2.

•The transmitter can be rotated on the sensor or the mounting bracket, up to 360° in 90° increments.
