Description
The Bently Nevada 3500/65 145988-02 +172109-01 is a 16-channel temperature monitor designed for core protection of large industrial machinery. This module monitors RTD or thermocouple signals in real time and provides uninterrupted thermal condition monitoring for bearings, windings, and critical process media.
Applications
Thermal power plants: Real-time monitoring of bearing temperatures at all levels and stator winding temperatures in steam turbine generator sets to prevent equipment damage caused by excessive thermal stress.
Oil and gas refineries: Operating in large centrifugal compressor units, monitoring temperature changes in motor coils and process gases to ensure production safety.
Large fertilizer plants: Used in the power unit of ammonia synthesis units, utilizing its 16-channel high-density monitoring capability to achieve centralized temperature protection for the entire pump set.
Steel rolling mills: Monitoring the lubricating oil temperature of large main drive motors and rolling mill gearboxes, utilizing wide-temperature operating characteristics to ensure data reliability in high-heat workshop environments.
Mining and processing plants: Deployed in the power units of heavy-duty hoists or conveyor systems, using thermocouple sensors for rapid response and interlocking protection against motor overheating.
Maintenance and Troubleshooting
Troubleshooting: If the OK LED on the front panel is off, verify the connection status of the I/O module and the back panel. If the temperature reading is abnormally high, check the sensor lead resistance and verify that the sensor type setting in the configuration software is compatible.
Maintenance Recommendations: Regularly check the cold junction compensation accuracy, especially when the ambient temperature fluctuates drastically. When the Bypass LED is lit, the alarm function will be disabled; monitoring mode should be restored promptly after maintenance.
