Cooper Instruments PTA145-10 Specifications

PTG 135 - PRECISION PRESSURE TRANSDUCER

he model PTG 135 (gage pressure) and PTA 145 (absolute

pressure) are designed for rugged industrial applications

T

requiring high accuracy pressure measurements. These
transducers are designed with 4 arm 350 ohm strain gage bridge and have
welded stainless steel construction. Using a “True Gage” design, the PTG
135 utilizes a second welded diaphragm that hermetically seals the strain
gage circuitry which allows the transducer to reference atmospheric
pressure. The PTA 145 absolute pressure units utilize an internally sealed
0 psia reference. All transducers have excellent long term stability.
