for more details. When mounting the gauge, be aware of the environment in which the gauge is operating. Steam, mist, coolant on the material, ambient temperature, scale and slag may all affect the performance of the gauge.

These environmental conditions may need to be modified as mentioned above in order to maximize the performance of the gauge.

Mounting Location

When mounting the gauge over the

 

material, be sure the gauge is not

 

directly over a roller or some other

 

device. If the laser beam from the gauge

 

strikes an object, it may detect a false

 

Material Present. In this case, the gauge

 

will not be able to detect when the

 

actual material is not in the

Standoff

measurement volume.

Distance

 

A device that captures most of the laser

Present readings. The beam dump

 

should be far enough from the gauge

that it cannot be measured. A good guideline is to place the beam dump at least double the standoff distance from the gauge.
