产品介绍
The Bently Nevada 991 Thrust Transmitter (型号: 991-25-70-01-00) is a compact signal conditioning device designed for axial position (thrust) measurement in rotating machinery. It converts the raw signal from an eddy current proximity probe into a standardized output suitable for control systems, protection systems, and distributed control systems (DCS).
This transmitter is typically used in applications where monitoring shaft axial displacement is critical for machinery protection, such as turbines, compressors, and pumps. It provides a reliable interface between the proximity probe system and plant control infrastructure, ensuring accurate and stable signal transmission.
The 991 Thrust Transmitter is engineered for industrial environments, /fering robust performance under vibration, temperature variation, and electrical interference. Its compact design allows easy installation in control panels or field enclosures, making it suitable for both new installations and retr/it projects.
