It has output through BNC and if I hook it up to a scope or a daq board, I see nothing but some 50Hz noise when the hammer is hit. There is no direct output.
But when I use this hammer with this amplifier I get proper readings.(I don't know it is the proper type of amplifier for this hammer but it worked)
After I read this document I'm further confused.
Does this hammer have any built in amplifier in it?(Is it charge type or voltage type?) The data sheet says 100mV/LBF but I get no signal without amplifier.
What type of force sensor is it?
