ABB 266DRH Pressure transmitters with seals 266DRHFSSB4B1V1E1L1I2

General description

Models detailed in this data sheet apply for those transmitters which include one or two remote seal(s) connected via a capillary to the transmitter sensor. Depending on the selected ordering code the following models are available: a) model 266DRH which allows a differential measurement using either • two remote seals of same type and size or • one direct mount seal on positive side and one remote seal on negative side, of same type and size or • one remote seal on positive side and a standard threaded connection direct 1/4 in – 18 NPT on flange or 1/2 in – 14 NPT through adapter, for the wet or dry leg on negative side opposite to seal, or • one direct mount seal on positive side and a standard threaded connection direct 1/4 in – 18 NPT on flange or 1/2 in – 14 NPT through adapter, for the wet or dry leg on negative side. b) model 266HRH or 266NRH have the remote or direct mount seall on the positive side and the user can select the suitable code for having the reference at armospheric or vacuum pressure respectively for gauge or absolute measure. Direct mount seal is integral to the transducer by a short capillary connection inside a protective rigid tube. This construction forms a standalone single assembly suitable to be mounted to the process by the seal(s) mounting facilities. All data apply for identical characteristics of the two sides when the transmitter is differential with two seals.
