Gauge pressure transmitter 261GC, 261GG, 261GJ, 261GM, 261GN

The compact transmitter class for gauge pressure and level with frontbonded diaphragms works within a broad selection of variants, options, fill fluids and wetted materials.

The compact, robust transmitter housing is made of 316 stainless steel as a standard. Due to its high corrosion resistance it can be used in a wide variety of process and ambient conditions without any problems. The user friendly display allows simple and intuitive local transmitter operation. Full device support, including diagnostic / maintenance information is guaranteed via the Device Type Manager software used in either a stand alone or system engineering tool. The transmitter provides local zero and span adjustments even without display.

The wide range of available process connections meets even special industrial requirements:

  • Threaded connections: e.g. for the power, pulp/paper, or oil and gas industries
  • Flange connections: e.g. for the chemical industry
  • Hygienic connections: e.g. for the pharmaceutical or food and beverages industries
