The CS90 Downhole Pressure Sensor uses a fully active four arm Wheatstone bridge, dielectrically isolated bulk silicon sensing element based on proprietary technology. This pressure sensor was designed to withstand the high pressure, high temperature environments that are common in downhole oil and gas exploration. The compact design allows for installation in downhole tools without sacrificing space. Standard offering includes a 3/8”-24 UNF-2A with 74˚ cone process connection, compensated millivolt output signal, 12.7 mm diameter housing, and solder hooks. An additional PT1000 RTD temperature output is standard for further measurement capabilities.
The CS90 Downhole Pressure Sensor has been independently tested to meet shock, vibration, and over-pressure standards.
The CS90 Downhole Pressure Sensor offers a typical compensated output of 10mV/V with a maximum excitation of 10 VDC. This provides a large amount of usable output, simplifying signal conditioning. For legacy installations, 2.6 mV/V is available. Additional output sensitivities are available upon request. All of these features come in a small, compact package with a typical diameter of 12.7 mm. The CS90 comes standard without a hex on the front end of the pressure sensor (near the process connection threads) to ensure fitment in drilling tools with confined spaces. A hex comes standard on the back end of the sensor (near the solder hooks) which can be used during installation.
For applications requiring calibration data, Core Sensors offers various options:
The US Oil Rig Count, hovering around 500 as of December 2023, has seen a nearly 185% increase since the height of the pandemic. In order to keep up with this growing demand, companies within the upstream supply chain need to ensure they have the appropriate tools and equipment to effectively and efficiently identify and extract natural resources from the ground.
When identifying and extracting these resources, pressure and temperature must be monitored to ensure the health and continued performance of the equipment as well as the integrity of the well. Unfortunately, the oil and gas industry has been plagued with long lead times and few suppliers when sourcing pressure and temperature measurement instrumentation. This, coupled with the growing demand for new tools, has resulted in a lot of frustration. We have heard the frustrations and are excited to announce a new standard in downhole pressure and temperature measurement, the CS90 Downhole Pressure Sensor.
