Diaphragm Withstands Pulverized Coal

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
