ABB pressure transmitters comply with dual seal standards

July 21, 2008 - ABB Instrumentation announced that its 2600T Series pressure transmitters of type 264, 268, and 364 have received compliance with the Canadian Standards Association (CSA) electrical code rules for dual seals. Canadian Electrical Code rules that apply to dual seals include 18-092(1), 18-108(1), and 18-158(1). Instrumentation destined for the oil and gas market in Canada must now often comply with these standards. These instruments also comply with ANSI/ISA 12.27.01 Dual Seal Standards.

The dual-seal standards require a secondary seal to prevent migration of flammable or combustible process fluids into electrical systems upon failure of a primary seal. Examples include diaphragm seals, thermowells, and pump seals. Devices that comply with these standards have undergone extensive testing involving temperature and fatigue cycling, overpressures, and leakage checks.

ABB is a leader in power and automation technologies that enable utility and industry customers to improve their performance while lowering environmental impact. The ABB Group of companies operates in around 100 countries and employs about 107,000 people.ABB Instrumentation operations in Canada are headquartered in Burlington, Ontario.
