Housed in stainless steel, Model P255 takes pressure measurements from 0-15 to 0-1,000 psi, and is fitted with ceramic diaphragm that withstands liquid and gas. Transducer is excited by 5 Vdc and provides linear amplified output of 0.5-4.5 Vdc that is proportional to pressure. It includes over-voltage, reverse polarity, and short circuit protection.
