in accordance with
ANSI/ISA 12.27.01
Endress+Hauser devices are designed in accordance with ANSI/ISA 12.27.01. allowing the
user to waive the use and save the cost of installing external secondary process seals in the
conduit as required by the process sealing sections of ANSI/NFPA 70 (NEC) and CSA 22.1
(CEC). These devices comply with the North American installation practice and provide a
very safe and cost-saving installation for pressurized applications with hazardous fluids.
Further information can be found in the control drawings of the relevant devices.
