The Model A-205a high level output, flush diaphragm pressure transducer features 4 mA to 20 mA, 1 Vdc to 5 Vdc or 1 Vdc to 10 Vdc (unipolar) output with an unregulated power supply. Model A-205a gage pressure transducers are manufactured with a unitized 17-4 PH Stainless Steel diaphragm. The advantage of this type of design is that a thin diaphragm and heavy sidewalls are made from one piece of stainless steel. This unitized diaphragm is rug­ged, but at the same time can be made thin enough to measure low pressures. Available pressure ranges span from 300 psig to 10000 psig. These models can be used in corrosive fluid environments.

Model A-205a has welded electrical connectors as an integral part of the transducer body and recommended for applications involving rough handling or where an all-welded stainless steel transducer is required.All units have four (4) active bonded strain gages arranged in a Wheatstone-bridge configuration.
