The ABB 266DRH is a differential pressure transmitter suitable for measuring liquid, gas or steam flow as well as level, pressure and density characterized by the remote seal construction.

Thanks to Taylor’s “All-Welded” technology in remote seal manufacturing as well as to the longstanding expertise, 266DRH can offer unmatched total performances and a wide selection of options such as fill fluid, diaphragm material, capillary protection and mounting connections.

ABB, leader in severe process measurements, is able to provide the right solution for the most critical process media at extreme ambient and process conditions. The long-term stability and its proven reliability make of 266DRH the best application solution for differential pressure measurements.

In addition to the plug-in terminal block, this transmitter features in-field replaceable electronics module that thanks to the auto-configuration functionality dramatically improves plant productivity. Its intuitive plug-and-play display with easy setup procedure really helps users by saving time and lowering maintenance and inventory costs. Moreover, the innovative TTG (Through The Glass) technology allow users to configure the instruments in the field without removing the windowed front cover and consequently to save a lot of time.

Thanks to the IEC61508 certification (SIL2/SIL3 loops) and the hardware/software redundancy with MTBF of over 100 years, the 266DRH represents the smartest solution in Safety loop applications.
