Bently Nevada 133819-02 3500/61 RTD/TC Temperature I/O Module
The Bently Nevada 133819-02 is a 3500/61 RTD/TC Temperature I/O Module available as Brand New, Original Stock with Global Shipping. Features 6 independent monitoring channels.
Description
The Bently Nevada 133819-02, also cataloged as the 133819-02 Temperature I/O Module, operates as a dedicated hardware component for conditioning temperature transducer signals within 3500 Machinery Protection System platforms. The module interfaces directly with backplane communication networks to route digitised temperature data to the main rack processor.

Eddy-Current Probe Scaling and Rotor Dynamics
While primarily executing temperature data acquisition, the module shares the 3500 system framework which relies on eddy-current probe scaling to align radial and axial machine dynamics. Integrating temperature profiles alongside standard gap voltage validation (-10 VDC targets) allows operators to monitor thermal growth vectors alongside primary rotor dynamics. Cross-talk suppression logic inside the backplane bus ensures that the 6 high-density temperature monitoring traces do not introduce electrical noise into adjacent proximity vibration monitor channels.
Frequently Asked Questions
Q: What happens to the thermocouple full-scale tracking range if ambient rack temperature exceeds +35 deg C?
A: When operating above +35 deg C ambient, the available full-scale temperature monitoring range for certain thermocouple configurations scales down to a maximum of +1000 deg C (+1832 deg F).
Q: Does the 133819-02 module provide independent recorder outputs for each loop?
A: Yes, as a constituent component of the 3500/61 system, this specific I/O hardware revision provides independent analog recorder outputs for all 6 measurement channels.
Field Installation Guidelines
- Power down the 3500 system rack backplane before inserting or extracting the rear-mount I/O module from its chassis slot.
- Terminate the 3-wire or 2-wire RTD passive leads directly into the internal terminal blocks using a calibrated torque screwdriver.
- Keep high-voltage AC electrical distribution lines routed in separate physical trays away from the low-voltage thermocouple signal wires.
- Ensure the cold junction compensation sensor mounted on the terminal strip remains clean and free from thermal draft interference.
- Secure both top and bottom module retaining fasteners into the rack frame to maintain ground integrity through the metallic faceplate.
