Are there any models that allow me to set up an upper or lower limit limiter on the instrument's input signal?

You can do this with a limiter or broken-line approximation function. You can use the following for this: M series plug-in type signal conditioners, VJ series compact plug-in type units, or F/W series front panel terminal type computing units. The broken-line approximation function can also be covered with the M series isolator (MH5).
