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

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.
