  • Vented gauge reference allows for low pressure ranges.  
  • F250C female process ports are available for robust high-pressure process connections. 
  • Class 1, Div 1, Groups A, B, C, D approvals for the AST46HA make the transmitter suitable for use in acetylene and hydrogen environments.
  • Sealed gauge versions are approved for Class 2, Div 1 Groups A,B,C,D for mining applications and installations.
  • A failure mode indicator option of the AST64H allows a user to choose an output signal that rails or drops during a fault condition.
  • Waspalloy, a new wetted material option, is available for both pressure transmitters in addition to Inconel 718, 17-4 PH & 316 L SS.
