ABB Pressure Transmitter 266HRHMRRA1 E4B6I2

Model 266HRH is a high overload gauge pressure transmitter characterized by the remote seal construction and suitable for measuring liquid, gas or steam flow as well as level, pressure 9IBA186676_400x400and density.

Thanks to Taylor’s “All-Welded” technology in remote seal design and manufacturing, 266HRH 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 266HRH the best application solution for gauge 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.
SIL2/SIL3 certification issued by TÜV Nord according to IEC 61508 represents another key-feature within 266 pressure transmitter portfolio. This certification is a real guarantee of protection and makes of 266HRH the smartest fit in Safety-critical loops.
