The 266NRH is a high-pressure resistant absolute pressure transmitter with a direct-mounted diaphragm seal. Its high reliability and stability make it an ideal choice for absolute pressure measurement.
- By adopting Taylor’s fully welded technology in the production of diaphragm seals, this absolute pressure transmitter delivers unparalleled performance even under extremely harsh environmental and process conditions.
As a leader in harsh-condition measurement, ABB is able to provide ideal solutions for key-point measurement under severe environmental and process conditions. The long-term stability and reliability of the 266NRH make it an ideal choice for absolute pressure measurement. The transmitter’s electronic module features an auto-configuration function, which can shorten downtime and increase productivity. Furthermore, the innovative TTG (Through-The-Glass) window technology allows on-site operations in explosive-proof environments without opening the cover, saving a significant amount of time.
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 266NRH suitable for safety-related applications.
The 266NRH supports the WirelessHART communication protocol, which eliminates a large number of wiring issues, thereby shortening on-site installation time and helping customers save construction costs.
The battery life of the 266NRH can reach 10 years at an update rate of 32 seconds, providing customers with a low-cost and reliable measurement solution.
