Model 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.

266DRH can offer unmatched total performance 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.

Replacement plug & play electronics with auto configuration capability help in reducing maintenance time and  costs. The Easy Set-up menu provides configuration and zero trim in minutes without the need of an expensive  communicator.  
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 266DRH the smartest fit in  Safety-critical loops.

266DRH features WirelessHART communication protocol allowing a shorter installation times by eliminating complex wired  infrastructures, and lower overall implementation costs of process measurement.  
266DRH battery life is about 10 years at 32 sec. update rates, delivering a very cost effective and reliable solution  to monitor your process assets.
