Core Functions

1. Multi-type Temperature Sensor Signal Acquisition with 16 Independent Channels This single module integrates 16 separate measurement channels, compatible with two mainstream temperature measuring components: thermocouples (Type K, T, E, J) and PT100 RTD sensors. It collects temperature signals from turbine casings, bearings, lube oil, motor stators and other measuring points.
2. Hardware-based Monitoring & Judgment with Multi-level Temperature Thresholds Equipped with independent hardware calculation circuits that operate without relying on software. Two tiers of thresholds (alert and danger) can be configured for each channel. The module continuously compares measured temperatures with preset limits to identify over-temperature conditions automatically.
3. Interlock Contact Output for Over-temperature Protection Once any measuring point exceeds the dangerous temperature limit, the built-in passive dry contacts will act to send digital signals to the unit PLC or ESD system. It can trigger local alarms, unit speed reduction or emergency shutdown interlocks to avoid severe damage such as burnt bearings and failed shaft seals caused by excessive heat.
4. Full-channel Real-time Self-diagnosis The module continuously monitors sensor open circuits, short circuits, loose wiring and internal hardware defects. Fault codes will be generated and transmitted to the 3500 rack chassis with local alarms activated once abnormalities are detected.
5. Centralized Data Communication & Upload Real-time temperature readings, over-temperature alarms and channel fault data of all channels are transmitted to the rack interface module via the rack backplane bus. Data can be further uploaded to DCS and HMI systems for temperature curve recording and historical data retrieval.
6. Plug-and-play Modular Rack Design It fits standard slots of the 3500 instrument rack and supports hot swapping. It can be installed together with vibration, overspeed and shaft displacement cards inside one 19-inch rack, enabling flexible expansion of temperature measuring points to match turbomachinery of various capacities.

Application & Purpose

1. Compatible System: Bently Nevada 3500 rack-mounted machinery protection monitoring system; this is a special temperature measurement accessory card for the platform.
2. Applicable Equipment: Gas turbines, steam turbines, large centrifugal compressors, axial fans and turbomachinery on offshore oil & gas platforms.
3. Target Industries: Thermal power plants, natural gas compression stations, petrochemical refineries, offshore oil & gas production platforms and coal chemical air separation plants.
4. Core Value: It monitors bearing temperature, lube oil temperature and casing process temperature of rotating equipment 24/7 to provide early warning of overheating faults. It prevents catastrophic equipment failures including bearing seizure, high-temperature blade damage and lubrication system breakdown. As a vital part of the unit safety protection system, it complies with the API 670 standard and serves as an essential temperature monitoring component for all large turbomachinery units.
