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. Integral high temperature cable can be added upon request. A PT1000 temperature output is available for further measurement capabilities.
