Bentley 3500/61

Description

Parameters and specifications
Number of channels: Bentley 3500/61 offers six temperature monitoring channels that accept temperature input from resistance temperature detectors (RTDS) and thermocouples (TCS).
Output: Compared to 3500/60, the 3500/61 offers an additional 4-20mA recorder output for each of its six channels.
Processor and memory: Although specific technical parameters are not given directly, similar DCS modules may have a high-performance processor and enough memory to support complex networking applications.
Configuration software: Measurement configuration using the 3500 Framework configuration software allows users to configure the RTD/TC non-isolated version to accept either TC or a mixture of TC and RTD inputs.
Size and weight
Dimensions: Specific physical dimensions (such as length, width, and height) are not explicitly given in search results. But the 3500 frame comes in two sizes: the full-size frame (19-inch EIA frame with 14 available module slots) and the mini frame
series
Series: Bentley 3500/61 belongs to Bentley Nevada’s 3500 series, a family of products for mechanical condition monitoring.

trait
Multi-channel monitoring: Provides six independent temperature monitoring channels for a variety of application scenarios.
Recorder output: 4-20mA recorder output for each channel for easy data recording and analysis.
Programmable alarms: Users can set programmable alarm setpoints for each channel to drive alarm and relay logic.
Isolated version: RTD/TC non-isolated or TC isolated versions are available. The TC isolated version provides 250Vdc channel isolation to prevent external interference.
Three-mode redundancy (TMR) support: When used in a three-mode redundancy configuration, the system employs two types of voting to ensure accurate operation and avoid a single point of failure.
effect
Temperature monitoring: mainly used to monitor the temperature of key equipment, such as radial bearing or thrust bearing metal temperature, compressor suction and exhaust temperature, steam temperature, motor temperature, etc.
Fault warning: By setting the alarm set point, when the temperature exceeds the preset value, an alarm can be issued to prevent equipment failure.
Data recording: Provide recorder output, convenient for users to record and analyze temperature data, for equipment maintenance and troubleshooting.
