The 266NSH absolute pressure transmitter integrates a high overpressure protection system. As a high-pressure resistant absolute pressure transmitter with a direct-mounted diaphragm seal, it is widely applicable and becomes an ideal choice for absolute pressure measurement due to its high cost-effectiveness and stable measurement performance.
In addition to traditional configuration tools (local buttons, LCD display, handheld communicator, or PC software), the innovative TTG (Through-The-Glass) window technology enables on-site operations in explosive-proof environments without opening the cover, saving a significant amount of time. This also confirms ABB’s commitment to customers: “Simplifying Complexity”.
A typical feature of the transmitter is that its electronic circuit board has a self-configuration function, allowing on-site replacement, which helps improve factory efficiency. The unique hot-swappable on-site display enables extremely convenient setup and configuration, helping customers save time as well as maintenance and spare parts costs.
Obtaining SIL2/SIL3 certificates issued by TUV Nord in accordance with the IEC 61508 standard is another prominent feature of the 266 product series. This certification serves as a safety guarantee, making the 266NSH suitable for safety-related applications.
The 266NSH supports the WirelessHART communication protocol, enabling access to more information beyond pressure measurement values. Now you can monitor measurement points that are difficult for employees to reach, ensuring the personal safety of employees. The battery life of the 266 wireless pressure transmitter can reach 10 years at an update rate of 32 seconds, providing customers with a low-cost and reliable measurement solution.
Without the problem of complex cable installation, the construction period can be greatly shortened and the overall operating cost can be reduced. Measurement can be simplified through ABB’s wireless instruments.
