Absolute pressure transmitter 266VRH


The compact transmitter class for absolute pressure with frontbonded diaphragms works within a broad selection of variants, options, fill fluids and wetted materials.


Thanks to Taylor’s “All-Welded” technology in remote seal manufacturing as well as to the longstanding expertise, 266VRH 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 266VRH the best application solution for absolute pressure measurements.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.

The SIL2 and SIL3 certification, issued according to the IEC 61508 international manufacturing standard, represents another key-feature on 266VRH that becomes the smartest solution in Safety loop applications.
