Minimize noise

Hello Everyone,
I am attempting to analyze timing of pulses from two inductive proximity sensors using a tektronix 2200 Digital storage oscilloscope. The problem is that the sensors are in a noisy environment mainly 480vac power feeding power to motors on the equipment ect... My question is. Is there a type of probe I can use to minimize the electrical noise or a method of setting up the scope I am using? I am currently using standard x1/x10 probe. My signal is 24vdc that pulses to 0vdc for 50-200ms at 120 pulses/min.
Any input would be appreciated. Thanks Mike K

Use a differential probe measurement - if the scope can do it. You just need to carefully match the probes - .... "easy to say" ..... of course!
