Overview:

Bently Nevada 3500/61E Temperature Monitor
Bently Nevada 3500/61E is a 6-channel temperature monitoring module. Along with the 2-channel 3500/67E, this module is part of the 3500 Series temperature monitoring products. The module supports two types of temperature inputs: Resistance Temperature Detectors (RTD) and Thermocouples (TC), with the TC type providing 500 Vdc channel-to-channel electrical isolation. The module processes input temperature signals and monitors critical temperature points of rotating machinery such as bearings, motor windings, and process fluids.

Function & Features:

- Multi-channel and Dual Input: The 3500/61E has 6 temperature monitoring channels, allowing simultaneous monitoring of 6 equipment measurement points, and supports both RTD and TC temperature sensor inputs.
- For the New Standard 3500 System: The 3500/61E is the only six-channel temperature monitoring module for the standard 3500 ENCORE system rack. In this application, temperature sensors (RTD or TC) are directly connected to the standard terminal board installed at the rear of the 3500 rack.
- For Upgrading 3300 Systems to the 3500 ENCORE Rack: The 3500/61E module works in conjunction with I/O modules that are compatible with the 3300/30 and 3300/35 six-channel temperature monitors.
Questions & Answers
💡 FAQ
Q: How to Set Up and Program the 3500/61E Module?
A: All parameters, such as sensor type, alarm setpoints, and ranges, are configured on a computer using the Bently Nevada dedicated 3500 rack configuration software.
Q: What is the difference between the 3500/61E and 3500/67E?
A: 3500/61E: 6-channel temperature monitor.
3500/67E: 2-channel temperature monitor.
Q: What special role does the 3500/61E play when upgrading old systems?
A: When users upgrade an old 3300 system rack to a new 3500 ENCORE rack, the 3500/61E module must be used to pair with the existing 3300/30 or 3300/35 six-channel monitor I/O modules and wiring if users wish to retain and reuse the originally installed field modules.
Q: What is the return and exchange policy?
A: Returns or exchanges are accepted within 7 days of receiving the goods if there are any quality issues, excluding damage caused by human error or misuse.
Q:What is the warranty period?
A: 1 year.
