| New Release of Pressure Transducer PA−750/758 |
|
| Tokyo, Japan – NIDEC COPAL ELECTRONICS CORP. released this month a new product "PA−750/758 series".
The new PA−750/758 series have been developed for pressure measurement of gases/liquids for applications in
the general industrial equipment and medical equipment.
They feature compact & light weight, high accuracy, and high corrosion resistance by adopting a diffusion type
semi-conductor pressure sensor as a pressure sensing element, SUS316L as the diaphragm, and a digital
temperature compensation circuit.
They are expected to be adopted for various applications, such as machine tools, refrigerating machines,
compressors, water processors and so on.
