Emerson Transmitter 350 Mode D’Emploi

2. Identify Proper Orientation of Transmitter:  

There are a few possible orientations of the 

LTM Series transmitters, they are:

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.  

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.
