Core Sensors Receives ANSI/UL 122701 Single Seal Certification

July 27, 2020

Core Sensors has received a Certificate of Compliance from CSA for a series of pressure transducers that meet ANSI/UL 122701 Single Seal standards.

ANSI/UL 122701 is a standard that “provides specific requirements for process sealing between electrical systems and flammable or combustible process fluids where a failure could allow the migration of process fluids directly into the electrical system.” Source:

The Single Seal marking will be added to the CS50 Non-Incendive and CS80 Intrinsically Safe pressure transducers. Along with the Single Seal marking will be Class I, Division 2 Non-Incendive (Groups A,B,C,D) (CS50) and Class I, Division 1 Intrinsically Safe (Groups A,B,C,D) (CS80) approval markings.

The addition of this single seal certification allows Core Sensors to manufacture pressure transducers in a more cost-effective manner while keeping the overall size of the sensor to a minimum.
