Pressure Transmitter Model 266AST is the top performance absolute pressure transmitter suitable for liquid, gas, or steam applications. It provides a broad selection of options, such as fill fluids and wetted materials, allowing operation even with critical process media in a harsh environment. Long-term stability and proven reliability are the key-factors of 266AST.
Absolute Pressure Transmitter
In addition to the plug-in terminal block, this Pressure 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.
The Pressure Transmitter 266AST 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).
