The 266GST is a gauge pressure transmitter with 0.04% base accuracy (optional 0.025%), supporting spans from 0.2 kPa to 600 kPa across sensor codes. It meets IEC 61508 for SIL2 (1oo1) and SIL3 (1oo2), and complies with PED category III and RoHS II. Turn-down ratio reaches 100:1, with damping configurable from 0 to 60 seconds and turn-on time under 10 seconds. TTG (Through-The-Glass) technology enables local configuration without opening the cover. Insulation resistance exceeds 100 MΩ at 500 V DC. Housing options include aluminium alloy or AISI 316L stainless steel, with multiple process connections and electrical entries. Output types include HART, PROFIBUS PA, and Foundation Fieldbus. Diaphragms are available in AISI 316L or Hastelloy C-276 with silicone oil or Galden filling.
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).
