266GST – Gauge pressure transmitter

Model 266GST is the top performance gauge pressure transmitter suitable for measuring liquid, gas or steam pressure as well as liquid level in an open tank. Thanks to its stability and reliability it 266GST_AST_GSH_ASH_mirrortif_400x400works within stated performance even in 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 266GST 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).
