Competitively priced yet high quality, the AST4700 pressure sensor is an all stainless steel, media isolated pressure sensor intended for use in the measurement of gases and liquids compatible with stainless steel. The AST4700 pressure sensor is suitable for test stands, steel mills, data loggers, and pressure instrumentation. AST4700 pressure sensors and transducers have been designed specifically for applications with demanding price and performance requirements.

AST4700 pressure sensors and transducers offer both millivolt and high level outputs. The high strength stainless steel sensing element contained in each AST4700 pressure sensor is machined from a solid piece of stainless steel, resulting in construction that contains no silicone oil, no welds, and no internal O-rings. With the AST4700 pressure sensor, measurements are available in gauge pressure covering ranges up to 10,000 PSI.

Applications for the AST4700 Pressure Sensor

  • Hydraulic systems
  • Train braking circuits
  • Test stands
  • Data loggers
  • Energy & Water Management
