  • Compact and rugged design
  • High strength stainless steel construction
  • No internal fluid filled cavities
  • No internal O-rings
  • Wide operating temperature range
  • Low static and thermal errors
  • EMI/RFI Protection to 100V/m
  • Suitable for high shock and vibration applications

The AST5000 pressure sensor offers wet/wet differential pressure measurements of gases and liquids compatible with stainless steel. Compact and conveniently sized, the AST5000 pressure sensor contains no internal O-rings or fluid filled cavities, making it ideal for water management, gas pipeline instrumentation, filtration, natural gas compressors, and many other applications. In the event that either of the AST5000 pressure sensor's pressure ports is at full line pressure and the other at zero, no damage will be done to the pressure transducer / transmitter.

Like all pressure sensors from AST, the AST5000 pressure sensor has been designed specifically for applications with demanding price and performance requirements. With the AST5000 pressure sensor, measurements are available in differential pressures covering line pressures up to 1,000 PSI.

Applications for the AST5000 Pressure Sensor

  • Industrial OEM Equipment
  • Hydraulic systems
  • Train Braking Circuits
  • HVAC/R Equipment
  • Refrigeration
  • Offroad
  • Test stands
  • Data loggers
  • Filtration
  • Energy & water management
