CS-DHP Downhole Pressure Sensor

Brand: Core Sensors
Add Product to My Catalog

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 for the high pressure and temperature environment that comes with oil & gas exploration. The standard design offers a 3/8"-24 UNF-2A process connection, millivolt output signal, 0.49" (12.5 mm) diameter housing, and 3.28 feet (1 meter) of high temperature cable. An independent PT1000 temperature sensor output is available upon request.
