Key Technical Specifications

Sensor measurement ranges documented for the 3500/60 temperature monitoring system:

• 100 Ω platinum RTD, α = 0.00385: -200°C to +850°C
• 100 Ω platinum RTD, α = 0.00392: -200°C to +700°C
• 120 Ω nickel RTD: -80°C to +260°C
• 10 Ω copper RTD: -100°C to +260°C
• Type E thermocouple: -100°C to +1,000°C
• Type J thermocouple: 0°C to +760°C
• Type K thermocouple: 0°C to +1,370°C
• Type T thermocouple: -160°C to +400°C

The non-isolated I/O configuration can accept RTD and TC inputs, including mixed sensor types. These are system measurement ranges; actual configuration must match the installed sensor and monitoring application.

Product Introduction

The Bently Nevada 133819-01 is an RTD/TC non-isolated I/O module with internal terminations, designed for the 3500/60 Temperature Monitor. It provides the rear-side connection for up to six temperature sensor channels, accepting resistance temperature detectors and thermocouples for machinery temperature monitoring.

Its internal termination design allows field sensor wiring to connect directly to the rear I/O module. Each channel can be configured for the required sensor type, including mixed RTD and thermocouple applications. Correct matching with the 3500/60 monitor and existing wiring arrangement is essential when selecting a replacement.

Application Scenarios & Field Experience

Temperature monitoring is a key part of machinery protection. Bearing, winding, casing, and process temperatures can provide early warning of abnormal operating conditions. When an RTD/TC I/O module fails, the affected temperature signals may become unavailable or unreliable. Replacement requires checking the sensor type, wiring configuration, termination arrangement, and compatibility with the installed 3500 temperature monitor.

Typical application scenarios

1. Power Generation — Receives bearing and winding temperature signals from generators and associated rotating equipment.
2. Oil & Gas — Monitors compressor bearing and casing temperatures through RTD and thermocouple sensors.
3. Petrochemical Processing — Collects temperature measurements from pumps, process equipment, and rotating machinery.
4. Industrial Manufacturing — Connects temperature sensors on motors, gearboxes, and other critical machinery to the plant’s monitoring system.

Illustrative engineering scenario, not a documented customer installation: A plant reports missing temperature readings from several channels on a 3500/60 monitor. Maintenance personnel first check the field sensors and wiring before identifying a possible rear I/O module fault. They verify that the replacement is 133819-01 and that the existing monitor is a 3500/60 with internal termination wiring. After installation, each affected channel is checked against its sensor configuration and expected measurement range before the monitoring system is returned to service.

Standard Operating Procedure (SOP) for Quality Control

1. Visual & Origin Inspection

• Verify the Bently Nevada label, complete part number, and product identification.
• Inspect the PCB, connector interfaces, terminal headers, and housing for corrosion, damage, or signs of unauthorized repair.
• Check the internal termination connector arrangement and compare it with the existing installation.
• Review available OEM packaging and origin documentation.

2. Functional Testing

• Where a compatible 3500/60 test setup is available, check module recognition and system diagnostics.
• Verify the six-channel input arrangement using suitable RTD or thermocouple simulation equipment.
• Check channel readings against known input values.
• Review abnormal sensor indications and channel diagnostic status.
• Record which channels were tested and any limitations of the test setup.

3. Firmware & Configuration Verification

• The 133819-01 is a rear I/O module, not an independently programmable controller.
• Confirm compatibility with the front-mounted 3500/60 monitor.
• Check the monitor firmware and system software requirements against the existing rack configuration.
• Verify RTD/TC sensor selection, channel assignments, measurement ranges, and alarm settings.
• Confirm that the installation does not require the recorder-output configuration associated with the 3500/61.

4. ESD-Safe Packaging

• Handle the module using appropriate electrostatic-discharge precautions.
• Protect exposed connectors and electronic components with anti-static packaging.
• Use protective cushioning to prevent impact damage during transit.

5. Pre-Shipment Documentation

• Provide clear photos of the actual module and identification label.
• Confirm the exact part number and termination type.
• Provide available inspection records and report only tests completed on the specific unit.

Frequently Asked Questions (FAQ)

Q1: Can 133819-01 replace 133819-02?
A: No, they are assigned to different temperature monitor configurations. The 133819-01 is for the 3500/60, while 133819-02 is for the 3500/61, which provides recorder outputs. Confirm the installed monitor model before ordering.

Q2: What warranty do you provide for Bently Nevada 133819-01?
A: We offer a 12-month warranty, subject to confirmed order terms. The product condition and warranty coverage will be stated in the order confirmation.

Q3: Is 133819-01 available for immediate shipment?
A: Stock availability and condition must be confirmed before ordering. For confirmed available stock, our usual arrangement is shipment within one week after payment. Product photos and live video inspection can be arranged before shipment.

Q4: Does firmware compatibility matter when replacing this module?
A: The 133819-01 itself is a rear I/O module, so the main compatibility checks concern the 3500/60 monitor, rack configuration, and system software or firmware requirements. Verify these details before installing the replacement.

Q5: What should engineers check before installation?
A: Confirm that the front module is a 3500/60, check the internal termination arrangement, and record all six channel assignments and sensor types. Verify field wiring and RTD/TC configuration before commissioning. Follow the approved shutdown and electrical isolation procedures; do not disconnect temperature sensor wiring while the system is operating unless the site’s approved procedure specifically permits it.
