Emerson IFT9701 instruction manual Remotely Mounting the Transmitter

Chapter 3

Remotely Mounting the Transmitter

Note: The instructions in this chapter apply only if the transmitter will be remotely mounted from the sensor. If the transmitter is integrally mounted to the sensor, proceed to Chapter 4.

3.1Overview

To mount the transmitter remotely from the sensor, the following steps are required:

•Choosing the proper location (see Section 3.2)

•Mounting the sensor on a flat surface or instrument pole (see Section 3.3)

•Connecting the transmitter to the sensor (see Section 3.4)

3.2Choosing the proper location

Install the transmitter according to the conditions stated in Section 2.1. For mounting dimensions, see Figure 3-1.

Total length of cable from sensor to transmitter must not exceed 1000 feet (300 meters).

For bend radii of cables, see Figure 3-4, Figure 3-5, or Figure 3-6, according to the type of cable to be used.

3.3Mounting the transmitter

A transmitter that is to be remotely mounted from the sensor is shipped with an L-shaped mounting bracket. Attach the bracket to a rigid, stable surface or instrument pole that will not transfer excessive vibration into the transmitter.

3.3.1Guidelines for flat-surface mounting

•Use four 5/16-inch (M8) nuts (not included), suitable for the environment.

•Do not secure bolts to separate beams, girders, wall studs, etc., which can move independently.

•To prevent unnecessary stress on the mounting bracket, use washers to shim the bracket if the mounting surface is not flat.

•For more information, see Figure 3-2.

3.3.2Guidelines for pole mounting

•Use two 5/16-inch (M8) U-bolts for 2-inch pipe, and four 5/16-inch (M8) nuts (not included), suitable for the environment.

•For more information, see Figure 3-3.
