I have strain signal of a lateral beam of a car measured at sampling rate 1,200Hz from data acquiring system. Even after using temperature compensation in strain gage, we are getting drift. So i wanted to remove drift in post processing of the strain signal. I have tried using High pass filter (HPF) of order 10th with cutoff freq = 200Hz, but i am loosing peaks of the strain signal. So HPF is not useful.

Which filter is suitable to remove drift for strain signals? considering the fact that i want to retain peaks and what other methods i can use to remove the drifts?

Also What are the exact factors to consider in choosing the cutoff frequency for HPF? and how to check it is correct?

i have attached the strain signal and HPF filtered signal of 10th order.  

Thanks in advance.
