Features
SS403 series miniature flush pressure sensor has a small-sized flush diaphragm. The sensor allows the use of a smaller size G 1/4″ (1/4″ BSP), 1/4″ NPT, or M10 x 1 male thread for fitting where there is limited room or access to the process measurement point. It is designed based on the piezoresistive technology. Stainless steel welded structure and silicone oil filled. It offers a stable and accurate output signal of 4-20 mA. You can also select 0-5 Vdc or 0-10 Vdc. The range spans from 2 bar up to 600 bar.
SS403 series features a robust stainless steel construction. It incorporates the latest piezoresistive technology together with a custom IC amplifier. SS403 series offers excellent stability and accuracy over a long service life. Typical applications include food processing, pharmaceutical, petrochemical, waste water, and slurry handling.
