I think if you put it at the height of a pay phone or walkup ATM machine, you'll be in pretty good company. I imagine the people who've built those have already spent much research dollars on the proper height. You don't mention if you have operator input (keyboard or touch panel) as well, which these do, the absence of which might give you more leeway.
If it's in the vicinity of the operation or process being monitored, you probably would also like to have it situated such that the operator can look past the display to the process without turning around, for instance.
