    If you have an amplified transducer, or other amplified input, skip to Section 6.1.2, otherwise, if using a Dynisco transducer, the model number of the transducer will designate its own electrical output. For example, in plastic melt applications, the PT462E-5M-6/18 or TPT432A-10M-6/18 have...
  • Page 32 a strain gage (0-3.33 mV/V full scale) signal output. Amplified units have a number where the strain gage units have a letter (E or A). The PT4624-5M-6/18 has a 4-20 mA signal output; the PT4625-5M- 6/18 has a 0-5 VDC signal output, while PT4626-5M-6/18 has a 0-10 VDC signal output. In Industrial applications, amplified units have a middle or end number of 4, 5, or 6.
