Gauge pressure transmitter with remote diaphragm seal 266GRT

Gauge pressure transmitter with remote diaphragm seal 266GRT

Model 266GRT is the top performance gauge pressure transmitter with remote diaphragm seals suitable for measuring liquid, gas or steam pressure as well as liquid level in open tanks. Thanks to Taylor’s “All-Welded” technology in remote seal manufacturing as well as to the longstanding expertise, 266GRT 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. With a long-term stability and its proven reliability, 266GRT represents the best application solution for gauge pressure measurements.

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 266GRT 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).

Features

  • Designed for gauge pressure measurement with a remote diaphragm seal, i.e., the sensing diaphragm is located remotely via capillary, which is useful for media that are hot, viscous, corrosive or crystallising.
  • High-performance model: base accuracy specified as ±0.04% of span.
  • Wide span (measuring range) from 0.6 kPa … up to 60 000 kPa (≈2.41 inH₂O … 8 700 psi) depending on selected sensor/seal combination.
  • Supports multiple output/communication protocols: 4-20 mA + HART, and options such as PROFIBUS PA, FOUNDATION Fieldbus.
  • Features a local display and configuration via “Through The Glass” (TTG) technology – you can configure the instrument without opening the housing cover.
  • Certified for use in Safety Instrumented Systems: complies with IEC 61508 for SIL2 (1oo1) and SIL3 (1oo2) configurations.
  • Complies with the Pressure Equipment Directive (PED) Category III.
  • Utilises the manufacturer’s “All-Welded” remote seal technology — meaning high integrity, no leakage paths through the seal, suitable for severe process conditions.
