CS91 Series
**Disclaimer: Unless otherwise agreed in writing, Core Sensors products are not authorized for use in applications including medical devices, life support systems, in-flight aerospace, nuclear or any other application where the product failure could result in personal injury or death.
The CS91 High Temperature Pressure Sensor uses a fully active four arm Wheatstone bridge, dielectrically isolated bulk silicon sensing element based on proprietary technology. This sensor has been designed for continuous operation in high temperature applications (up to +200°C) such as engine test stands, environmental chambers and semiconductor manufacturing. Standard offering includes a metal-to-metal flare process connection, 10mV/V compensated output signal, 22mm diameter housing, and a high strength glass-to-metal seal electrical connection. An additional PT1000 RTD temperature output is standard for further measurement capabilities. The CS91 has been independently tested to meet IEC 60068-2-27 shock and IEC 60068-2-6 vibration standards. A replaceable Inconel 600 metal seal is included to ease installation.






The CS91 High Temperature Pressure Sensor offers a compensated output of 10mV/V with a maximum excitation of 10VDC. This provides a large amount of usable output, simplifying signal conditioning.
The CS91 is not only ideal for high temperature applications but it will also perform excellent in corrosive environments. For pressure ranges up to 10,000 PSI, Hastelloy C276 (UNS N10276) is the standard wetted material. For pressure ranges greater than 10,000 PSI, Inconel 718 (UNS N07718) is the standard wetted material.
All of these features come packaged in a ready to use pressure sensor that can be installed directly in the high temperature environment without the need for cooling adapters or other cooling accessories.
