The 990-04-50-01-CN proximity transmitter operates as an important signal conversion unit within a machinery monitoring system.
The proximity probe installed near the rotating shaft detects changes in the distance between the probe tip and the shaft surface. When the shaft moves due to vibration, imbalance, misalignment, mechanical looseness, or bearing problems, the probe generates corresponding electrical signals.
The transmitter receives these signals and performs signal processing, amplification, and conversion. The processed output signal can then be analyzed by monitoring systems to evaluate machine operating conditions.
This working method enables continuous observation of equipment health and allows maintenance personnel to identify potential mechanical problems before they develop into serious failures.
The product is suitable for steam turbine monitoring systems where accurate shaft vibration and displacement measurement are required.
Large turbines operate under high-speed and high-load conditions. Continuous monitoring helps detect rotor movement changes, abnormal vibration levels, and possible mechanical problems.
Gas turbines require reliable monitoring equipment because of their demanding operating environment.
The transmitter provides stable measurement signals that support turbine protection systems and help operators analyze equipment operating trends.
Industrial compressors often operate continuously for long periods. Mechanical faults such as imbalance, misalignment, and bearing wear can lead to unexpected shutdowns.
The 990-04-50-01-CN provides continuous shaft condition monitoring to improve compressor reliability and maintenance planning.
Large industrial pumps are widely used in energy, chemical, and manufacturing industries.
By monitoring shaft vibration and displacement, the transmitter helps detect abnormal operating conditions and supports preventive maintenance activities.
