UNCTIONAL DESCRIPTION:
3500/61 is a Temperature Monitor Module manufactured and designed by Bently Nevada as part of the 3500 Series used for monitoring seismic activity. The GE / Bently Nevada 3500/61 Series Temperature Monitors Modules offer six temperature monitoring channels and accept temperature inputs from both RTDs and thermocouples. These inputs are processed by the modules, which then compare them to user-programmable alarm setpoints. The 3500/61 offers the same functionality as the one except that it has recorder outputs for each of its six channels, which the does not. The 3500 Rack Configuration Software is used by the user to program the modules to take RTD or TC temperature data. The RTD/TC non-isolated and TC-isolated versions of several I/O modules are both available. The RTD/TC non-isolated version can be set up to take inputs that are either all RTD or all TC, or a combination of both. To guard against outside interference, the TC-isolated version offers 250 Vdc of channel-to-channel isolation.
FEATURES:
- Six Channels for Monitoring Temperature
- Resistance Temperature Detector and Thermocouple as Temperature Inputs
- Each channel’s output from the recorder
- TC Isolated or Non-Isolated RTD/TC Versions
The Bently Nevada 3500/61 Temperature Monitor Module is a high-precision and highly reliable temperature monitoring module, specifically designed for temperature monitoring of mechanical equipment in industrial environments. Here are its key features and application scenarios:
Core features
Multi-channel monitoring
It provides 6 temperature monitoring channels, supporting resistance temperature detectors (RTDs) and thermocouples (TCs) for input, enabling simultaneous monitoring of temperatures at multiple key points.
Measurement range: -200°C to 800°C, with an accuracy of ±0.1°C and a resolution of 0.01°C, meeting high-precision monitoring requirements.
Alarm and recording function
Supports programmable high and low limit alarms. Users can set alarm thresholds through the 3500 rack configuration software.
Each channel provides a 4-20mA recorder output, facilitating data recording and analysis.
Communication and interfaces
Supports RS-485 and Ethernet communication, and can be integrated with DCS, PLC, etc. systems.
Provides intuitive parameter settings and fault diagnosis functions, facilitating user operation.
High reliability and protection
Adopts a modular design, supports redundant configuration, ensuring system reliability.
Protection grade IP65, operating temperature range -40°C to 85°C, suitable for harsh industrial environments.
Isolation and anti-interference
The TC isolated version provides 250V RMS channel-to-channel isolation to prevent external interference.
In the triple modular redundancy (TMR) configuration, three units need to be installed adjacent to each other to ensure accurate system operation and avoid single-point failures.
Application scenarios
Power generation industry
Monitor the temperatures of steam turbines, generators, boilers, etc. to ensure the safe operation of the equipment.
Petroleum and natural gas
Monitor the temperatures of key equipment such as pumps, compressors, and pipelines to prevent overheating and other temperature abnormalities that may cause failures.
Chemical and steel industries
Monitor the temperatures during chemical production to ensure safe and efficient production; monitor high-temperature equipment in steel production to prevent equipment damage.
Other industrial fields
Applicable to industries such as papermaking and transportation, monitoring the temperatures of key equipment to ensure production continuity.
