Quick Detail

Description

The Bently Nevada 3500/65 145988-02 Temperature Monitor delivers precise monitoring across 16 channels, supporting 3-wire and 4-wire RTDs as well as isolated tip TCs (Type E, J, K, T). Each input features >1 MΩ impedance, ensuring accurate signal capture. The 3500/65 145988-02 processes temperatures from -160°C to +1370°C depending on transducer type and compares them to programmable alarm setpoints. Operating between -30°C and +65°C, the monitor occupies 1 full-height front slot, with I/O modules using a rear slot. LEDs on the front panel indicate OK, TX/RX communication, and Bypass Mode. Configurable via 3500 Rack Software, the 3500/65 145988-02 integrates seamlessly in TMR arrangements, employing dual voting to prevent single-point failures. Power consumption is nominally 3 W. RTD/TC resolution is 1°C or 1°F, with internal termination accuracy ±3°C at +25°C.

Applications

Monitor 16 Channels of RTD and Thermocouple Inputs
The 3500/65 145988-02 supports 16 channels of 3-wire RTD, 4-wire RTD, or isolated tip thermocouples (Types E, J, K, T). Each input has greater than 1 MΩ impedance, enabling the 3500/65 145988-02 to capture precise temperature signals from -160°C to +1370°C depending on transducer type.

Set Programmable Alarm Setpoints for Critical Equipment
With the 3500 Rack Configuration Software, the 3500/65 145988-02 allows operators to configure individual alarm thresholds for each channel, ensuring temperatures above ±3°C at +25°C trigger alerts, maximizing equipment monitoring accuracy.

Install in Triple Modular Redundant Configurations
In TMR arrangements, three adjacent 3500/65 145988-02 monitors work together with dual voting logic. This setup ensures temperature readings remain accurate even if one module experiences an anomaly, supporting uninterrupted industrial automation operations.

Track Temperature Status with Front Panel LEDs
The 3500/65 145988-02 provides OK, TX/RX, and Bypass LEDs on the front panel. Operators can visually confirm correct operation across all 16 channels and monitor continuous temperature input without interrupting processes.

Specifications

Competitive Advantage

Wide Temperature Range Measurement
The 3500/65 145988-02 measures temperatures from -160°C to +1370°C depending on transducer type, with ±3°C internal termination accuracy at +25°C, allowing precise monitoring for turbines, compressors, and motors.

Low Power Consumption for Continuous Operation
With only 3 W nominal power consumption, the 3500/65 145988-02 supports 16-channel monitoring continuously while minimizing energy usage, making it suitable for long-term industrial deployment.

Flexible Rack Integration
The main module of the 3500/65 145988-02 occupies 1 full-height front slot, and I/O modules occupy 1 rear slot, enabling easy integration into existing 3500 rack systems without additional hardware modifications.

Instant Signal and Communication Feedback
Front panel LEDs of the 3500/65 145988-02 provide real-time feedback on module operation, TX/RX communication, and Bypass Mode. This allows operators to immediately validate temperature signals across all 16 channels, reducing downtime and inspection needs.
