266DRH - Differential Pressure Transmitter with Remote Diaphragm Seal

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


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.
