Thanks Philrock:
The bearings were working well before but now are slipping. So I assume all the alignment ands upport were ok at one time.
Can these types of bearings wear out over years of use?
If so can I just replace them and hope for the best. Or do I need to turn down new shafts and...
Hi Guys:
I'm a EE ( sorry!) trying to understand how roller clutch bearings work. Knon of any sites that have a "how to" on these parts?
I have a Torrington roller clutch on a piece of old exersize equipment that in now "slipping" ( backlash?) in the torque direction.
I'm not sure if the...
When I get to that part , I'll post it. Thanks sreid
I do not need absolute DC readings. Just the change over time.
I need to get the info out and locally stored so AM was the choice for simple implementation and remote transfer.
I can pretty much dial out the DC at the load cell, so the...
The AD633 is first on the list, thanks sreid.
I do have a copy of the Analog Devices handbook ( now you know I'm an oldtimer!) that is where I got the multiplier idea, thanks John
I found another IC used for feedback generation, a Unitrode UC1901. It has an on board osc., multiplier, and...
Thanks John;
I was planning to use the carrier of 1KHz, the modulation is signal from a slowly changing (< 50 Hz) pressure transducer. Pretty much DC.
I'm stuck with this low freq app. due to some systems issues. I usually do RF circuits and I have used DGFets, but I was hoping for an op-amp...
Looking to xfer some low varying DC data.
Tired V to F converters and they proved problematic.
Thinking of simple AM scheme.
Looking at Gilbert cells/multipliers but is there a simple op-amp type AM modulator circuit?
