The Model 261GG is a gauge pressure transmitter with a direct mount seal and tri-clamp process connection per ASME, featuring a stainless steel housing optimized for harsh environments. It supports measuring spans from 0.3 kPa to 60000 kPa with base accuracy of ±0.1%. The transmitter is configurable via local buttons, an LCD indicator, or a handheld terminal, and offers optional HART digital communication with 4 to 20 mA output. Available fill fluids include silicone oil, white oil (FDA approved), and inert fluids. The housing has an M16 x 1.5 or 1/2-14 NPT electrical connection, and the device complies with PED under Sound Engineering Practice and Directive 2011/65/UE (RoHS II). Surface finish of wetted parts is Ra ≤ 0.8 µm, with electropolished options available. Explosion protection certifications include ATEX EEx ia, IECEx Ex ia, FM, and CSA.
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:
