Conventional installations involve sensing lines as long as 30 to 50
feet to transfer the sensed pressure to a rack of transmitters. The long
impulse lines are a maintenance headache, and often become plugged. The
2600T series pressure transmitter with a direct mount seal feature a
measuring diaphragm with a patented Diaflex coating that withstands
harsh environments. Using Physical Vapor Deposition (PVD), the 316L
Stainless Steel diaphragm seal is coated to a thickness ranging from 3
to 5 µm, which provides good sensitivity to the pressure, while
maintaining a Rockwell Hardness of 4000HV in a nominal flow rate of
162ft/minute.ABB www.abb.com/instrumentation800.829.6001
