1199 Direct Mount Diaphragm Seal
SKU: 1199
Direct-mount diaphragm seal that bolts to the high side of a Coplanar transmitter (3051C, 2051C, or 3051S_C). Couples process pressure to the transmitter sensor through an isolating diaphragm and silicone fill fluid — protects the transmitter from hot, cold, corrosive, viscous, or clogging processes. Configured factory-direct via the seals selection (S1/S2) on the 3051/2051 transmitter or the B11/B12 process connection on the 3051S. Flush Flanged (FFW) style covered by the online configurator; threaded, hygienic, and specialty seal styles available by quote.
