The all stainless steel AST4900 pressure sensor is a competitively priced, high quality, media isolated pressure sensor intended for use in the measurement of gases and liquids compatible with stainless steel. This series of pressure sensors from AST4900 is suitable for high purity gas delivery systems and data loggers. AST4900 pressure sensors and transducers have been designed specifically for applications with demanding price and performance requirements.

AST4900 pressure sensors offer both millivolt and high level outputs. The high strength stainless steel sensing element is machined from a solid piece of stainless steel, resulting in construction that contains no silicone oil, no welds, and no internal O-rings. Measurements are available in gauge pressure covering ranges up to 10,000 PSI. The AST4900's long life and high performance make it ideal for applications needing high accuracy, excellent long-term stability, and trouble free operation.
