CS-DHP Downhole Pressure Sensor

  • ≤ ±0.15% BFSL accuracy
  • Pressure from 5,000 to 30,000 PSI
  • High strength titanium-alloy 6-4 sensing element
  • Operating temperature from -195 to +204°C


The DHP series miniature pressure sensor uses a fully active four-arm Wheatstone bridge, dielectrically isolated Silicon on Sapphire sensing element based on proprietary technology. This sensor was designed to withstand the high pressure, high-temperature environments that are common in downhole oil & gas exploration. The compact design allows for installation in downhole tools without sacrificing space. Standard offering includes a 3/8”-24 UNF-2A process connection, uncompensated millivolt output signal, 12.5mm diameter housing, and solder hooks. The integral high-temperature cable can be added on request. A PT1000 temperature output is available for further measurement capabilities.
