All-Welded Design Protects Against Leaks

ABB”s 364 pressuretransmitter, a member of ABB’s 2600T family, features the company”s”Silver Bullet” design for pressure, differential-pressure, and flowapplications in process and municipal markets. The 364 transmitter’scompact design increases reliability by minimizing parts. Itsall-welded housing eliminates the need for seals — flanges, bolts, andgaskets — traditional paths for leaks. Slightly taller than a 12-ozsoda can, the 364 has a rugged, corrosion-resistant, stainless-steelhousing and process connection along with a Hastelloy C-276 diaphragm.Its base accuracy is 0.06 percent of the upper range limit (URL).Stability mantains errors below 0.15 percent URL over 10 years,reducing calibration frequency. An optional on-board two-inch LCDdisplay is also available, enabling users to navigate through aself-explanatory menu similar to those found in today’s cell phones.Advancedcapabilities add immediate value to a variety of applications. Theunits come with replaceable electronics, an auto-repairing database, abidirectional flow totalizer, programmable alarm setpoint saturationlimits, internal diagnostics, standard HART communications, and asquare-root cutoff. A 4-kV 1.2/20 µsec surge protector is standard, asis a high performance EMI filter. The transmitters may be ordered tocomply with several hazardous-area certifications, selectable by theend-user (e.g., FM, CSA, and ATEX).
