Description
The Bently Nevada 3500/65 145988-02 16-Channel Temperature Monitor is engineered for industrial and process applications, providing precise temperature monitoring across 16 independent channels. It accepts inputs from resistance temperature detectors (RTD) or isolated tip thermocouples (TC), enabling flexible configurations for various plant setups.

Each input features an impedance greater than 1 MΩ, ensuring accurate signal conditioning. The Bently Nevada 3500/65 145988-02 also provides a dedicated RTD current source of 913 ± 7 µA at 25°C per transducer, with one supply for 4-wire RTDs and two supplies for 3-wire RTDs. The module operates with a nominal power consumption of only 3 watts, making it energy-efficient.

Operational status is communicated via three LEDs: OK indicates proper operation, TX/RX confirms communication with other modules in the 3500 rack, and Bypass signals when the Bently Nevada 3500/65 145988-02 is in bypass mode. Resolution is 1°C or 1°F, with accuracy ±3°C at +25°C (±5.4°F at +77°F) for both bulkhead and standard racks.

Programming is performed using the 3500 Rack Configuration Software, allowing each channel to be configured for isolated tip thermocouples, 3-wire RTDs, 4-wire RTDs, or a combination of TC and RTD inputs. In Triple Modular Redundant (TMR) setups, the Bently Nevada 3500/65 145988-02 must be installed in groups of three adjacent units, using two types of voting to ensure accurate operation and eliminate single point failures. The module is designed for harsh environments, operating from -30°C to +65°C and storing safely from -40°C to +85°C with up to 95% non-condensing humidity.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What is the accuracy of the 3500/65 145988-02?
±3°C at +25°C (±5.4°F at +77°F) for both bulkhead and standard racks.
Does the Bently Nevada 3500/65 145988-02 have visual status indicators?
Yes, it has OK, TX/RX, and Bypass LEDs to indicate operational status.
How does the Bently Nevada 3500/65 145988-02 ensure high reliability in Triple Modular Redundant (TMR) configurations?
In TMR configurations, three monitors must be installed in adjacent slots. The monitor uses two types of voting to ensure accurate operation and eliminate single-point failures, ensuring that a single faulty channel does not cause a false trip.
Is the Bently Nevada 3500/65 145988-02 hot-swappable, especially during firmware upgrades?
While standard module replacement may support hot-swapping, firmware upgrades do not. You must remove the I/O module before upgrading the main monitor firmware. Failure to do so results in an "I/O Module Mismatch" error and a "562 ADC Failure" in the system event list.
