Bi polar differential amplifier assistance
(OP)
I am seeking a circuit whereby I can generate a +25...-25mV signal to simulate a load cell input. Does any one know where I can get this or how I create it.
Thanks for your help in advance

In this case you may want somehting like a strain gage simultor. BLH sells a couple of models.
Cheaper methods such as building your own whetstone bridge with and varying the leg resitances is easy but messy and harder to ensure confident measurements. Let me know if you like more details.
