ABB 266MRT differential pressure transmitter features remote diaphragm seals and multisensor technology for precise liquid/gas/steam flow measurement. SIL2/SIL3 certified with in-field configurability.
- Model series
- 266MRT
- Product characteristic
- Model 266MRT is the top performace 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.
- Product characteristic
- 266MRT 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.

In addition to the plug-in terminal block, 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 allows users to configure the instruments in the field without removing the windowed front cover and consequently to save a lot of time. The 266MRT is certified by TUV NORD for use in safety instrumented systems as per the requirements of IEC61508. The transmitters meet the requirements for SIL2 applications in a single transmitter configuration (1oo1) and for SIL3 applications in a redundant configuration (1oo2). For quotation, send the complete order code, quantity and operating conditions. Specifications and available options depend on the ordered configuration.
