2.Identify Proper Orientation of Transmitter: There are a few possible orientations of the LTM Series transmitters, they are:

Do not over tighten the clamps because they will bend and distort.

Figure 9. Possible transmitter configurations

Transmitter A is a standard top mount configuration.

Transmitter B is a top mount with elbow, usually utilized when there are temperature or head room issues. There is also a bottom mount with elbow configuration which is not depicted.

Transmitter C is a bottom mount transmitter with remote electronics. This configuration is utilized in more extreme temperatures or for accessibility.

There is also top mount with remote electronics which is not depicted.

3.Mounting the Transmitter. Align the 4/20 mA (or 0 and 100%) markings with the center of the top and bottom process connection. Mount the transmitter along the level gage and use a nut driver to tighten the clamps so the sensor probe of the transmitter is held securely (will not slip up and down). Keep the transmitter supported while the clamps are being tightened (this can require more than one person).

Figure 10. Top view of mounting clamps and sensor probe

A: Is the correct way to have clamps tightened.

The clamps do not have to meet.

B:Is incorrect because the clamp is flipped around and will not grip the sensor probe.

C:Is incorrect because the clamp has been tighten too much and damaged/distorted.

Effects of high vibration can be minimized early on by notifying the factory at time of order. The electronics can be remote mounted and special insulators can be installed. Please see the depiction below.
