Indirect load sensing

Indirect load sensing

Indirect load sensing

(OP)
I have been asked to monitor load induced pressure in a double acting cylinder using a pressure transducer or switch. This is intended to automate a process control or I would use a pressure gauge. I realize this is not as straightforward as load cells but I would like to use an existing cylinder if possible. Are there any companies that deal with this specifically?

Hi,
Try Hydac or Wika.
 

RE: Indirect load sensing

There are tons of companies out there that make pressure transducers.  Honeywell, Parker, I could go on for a while....  Besides all that, be sure to measure both sides of the piston (do a differential measurement) otherwise your load readings will be off.  I'm dealing with problems now from a previous engineer who relied on readings from only one end of the cylinder (and the valves created back pressure; killing the blind end readings).
