266DHH differential pressure transmitter with direct mount seal

Model 266DHH is a flange mounted differential pressure transmitter. With a maximum working pressure of up to 5Mpa (725psi), this transmitter represents the right solution for clean process fluids (generally water and glean oils).

266DDH performances are exceeding by far performance expectations of the direct mounted diaphragm seal versions.
