Features
Multiple Input Compatibility
The ability to interface with both RTDs and TCs provides flexibility. Different industrial applications may require the use of either type of temperature sensor based on factors such as accuracy requirements, temperature range, and cost. This module can accommodate these diverse needs.
High – Precision Measurement
Leveraging advanced signal conditioning and calibration techniques, it offers high – precision temperature measurement. This accuracy is essential for detecting even the slightest temperature variations in machinery components, which could be an early indication of a developing problem.
Real – Time Monitoring
With its real – time monitoring capabilities, the module continuously tracks the temperature of connected machinery. This allows operators to be immediately alerted to any abnormal temperature changes, enabling prompt action to prevent equipment failure.
Robust Design
Built with industrial – grade materials, it can withstand harsh environmental conditions. Whether it’s exposure to high temperatures, humidity, or vibrations, the module is designed to maintain its performance and reliability.
Easy Integration
As part of the 3500 series, it integrates seamlessly with other modules in the system. This simplifies the overall system setup and operation, reducing the complexity for end – users.
Function
The primary function of the 136711-01 is to collect temperature data from RTDs and TCs. Once the raw temperature signals are received, the module applies sophisticated signal conditioning algorithms. These algorithms remove any noise or interference from the signals and convert them into accurate temperature values. The conditioned data is then transmitted to the 3500 system’s data processing units. In the data processing units, the temperature data is analyzed in the context of other machinery parameters, such as vibration and speed. Operators can set programmable alarm thresholds for temperature. If the measured temperature exceeds these thresholds, the 3500 system can trigger alarms, which may be visual, audible, or sent as digital notifications to operators’ devices. This allows for timely intervention to prevent equipment damage.
Use
In industrial settings, the module is installed in the 3500 system rack. Technicians carefully connect RTDs or TCs to the module’s input connectors, ensuring proper wiring and calibration. The module is then powered up, and its settings are configured using the 3500 rack configuration software. Operators can use the software to define the type of temperature sensors being used (RTD or TC), set the alarm thresholds, and view real – time temperature data. Maintenance teams regularly check the module’s diagnostic information to ensure its proper functioning. In case of a sensor or module failure, the modular design of the 3500 system allows for easy replacement, minimizing downtime.
