Description
The Bently Nevada 3500/61 133811-02+133819-02 is a 6-channel high-performance temperature monitor designed specifically for rotating machinery. It is suitable for high-voltage isolation, various sensor inputs, and harsh industrial environments. This module supports field software configuration, features high-precision data processing capabilities, and provides real-time alarm protection via proportional current output, ensuring the safe operation of bearings and motor windings.
Applications
Thermal power plants: Real-time monitoring of turbine main bearing and generator stator winding temperatures, synchronizing thermal status to the central control room via a 4-20 mA output.
Oil and gas refineries: Monitoring cylinder head and critical bearing temperatures in reciprocating or centrifugal compressor units to prevent unplanned shutdowns due to thermal overload.
Large fertilizer plants: Deployed in high-pressure pump units of ammonia synthesis plants, utilizing 250 Vdc isolation to ensure data accuracy in environments with strong electromagnetic interference.
Steel rolling mills: Monitoring bearing housing temperatures of large main drive motors, utilizing their wide operating temperature range to ensure reliable monitoring in extreme industrial climates.
Mining processing plants: Used in heavy-duty hoists or conveyor systems, utilizing their high input impedance to reduce signal attenuation caused by long-distance sensor cables.

FAQ
Q: Does the 3500/61 133811-02+133819-02 support module replacement without system shutdown?
A: Yes. It is hot-swappable, but interlocking logic must be set to safe bypass before replacement.
Q: Will a short circuit in the recorder output damage the 3500/61 133811-02+133819-02?
A: No. It has short-circuit protection and continues normal data acquisition.
Q: What is the measurement resolution for a 10Ω copper RTD on the 3500/61 133811-02+133819-02?
A: Typically 1°C, but exact resolution depends on configuration settings.
Q: What are the load resistance requirements for the I/O module in the 3500/61 133811-02+133819-02?
A: Total resistance must be 0–600 Ω to ensure 12 Vdc compliance.
Q: Can the 3500/61 133811-02+133819-02 start in -30°C environments?
A: Yes. It supports -30°C rated operation for cold-climate use.
