 - Discontinued Compact Pressure Transmitter for Absolute and Sealed Pressures


Compact Pressure Transmitter for Absolute and Sealed Pressures | PX177

  • Waterproof Case for Harsh Environments
  • Compact Size for Ease of Use
  • Ideal for Freon and Ammonia Applications


The PX176/177 series has been discontinued. Please see the PX309 or PX181B as a possible alternatives or contact our Pressure Engineering department.

The PX177 utilizes silicon strain gages mounted on a beam coupled to a stainless steel diaphragm for maximum thermal isolation. The sensing element and internal electronics are protected from the environment by a stainless steel case.
