[PSUBS-MAILIST] PLC input question

[Sean T. Stevenson via Personal_Submersibles]

I often use full bridge transducers with the PACs I use, where a signal conditioning module on the PAC chassis provides the bridge excitation voltage and performs the appropriate scale conversion to engineering units from the millivolt signal return. Strain gauges and foil pressure transducers thus work the same way. If you need an industry standard output (i.e. 0-10V or 4-20 mA), your transducer must incorporate an appropriate signal amplifier.
