ABB 266DRH and 266MRT Differential Pressure Transmitter

ABB Differential Pressure Transmitter 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 the “All-Welded” technology inherited by Taylor in remote seal design and manufacturing, 266DRH can offer unmatched total performance and a wide selection of options such as fill fluid, diaphragm material, capillary protection, and mounting connections. ABB, the 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 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 for an expensive communicator. SIL2/SIL3 certification issued by TÜV Nord according to IEC 61508 represents another key-feature within the 266 pressure transmitter portfolio. This certification is a real guarantee of protection and makes 266DRH the smartest fit in Safety-critical loops.

266DRH features WirelessHART communication protocol allowing a shorter installation time 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.

ABB Differential Pressure Transmitter 266MRT

ABB Differential Pressure Transmitter 266MRT is the top performance differential pressure transmitter with “multisensor technology” suitable for measuring liquid, gas, or steam flow as well as level, pressure, and density characterized by the remote seal construction. The unique combination of several sensor systems in a single device allows simultaneous measurement of differential pressure and absolute pressure. The sensor temperature and the absolute pressure are also used for eliminating environmental effects on the sensor.

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