Nexperion Sentinel is a tool designed to maximise your transmission electron microscope’s uptime by constantly monitoring parameters from the microscope’s critical subsystems, its peripherals, and its environment. Alarms via E-mail or cell phone short message are triggered if parameters fall outside of the user-defined range, values are logged and can be checked online via an Internet status page.
Depending on the microscope’s and Sentinel’s configuration, the following subsystems and parameters are integrated into the tool:
- Vacuum system
- High tension system and emitter
- Specimen stage
- Water chillers: state, input and output temperature
- Pressure of media supplies: Compressed air, N2, …
- Cryogen level
- Environmental conditions: temperature, humidity, and floor flooding
- Network connectivity
- Free space on local disks and remote shares
- User log-ins
These parameters are subject to constant updates as our work develops and grows. Contact us to discuss the implementation of additional parameters to cover your individual needs.
Nexperion Sentinel comes with a graphical user interface for configuration of the highly customizable monitoring and logging facility.
Nexperion’s Sentinel is a great tool for a busy facility like ours, where up-time is key. Now we catch small problems before they turn into major issues causing microscope down-timeDr. Thomas Heuser, Head Electron Microscopy, Vienna Biocenter Core Facilities GmbH, Austria
One of Sentinel’s unique features is alerting of system supervisors instantly in case of problems, allowing a prompt response to an issue and eliminating unnecessary downtime and loss in productivity. These alarms and cancellations can be sent in several different ways:
- Mobile phone short message (SMS)
- Local notification
Optionally, a status website can be made accessible for each instrument on the Internet. On this (mobile-friendly) site, all parameters are listed with actual and expected values. A color coding allows a quick survey of the situation. To receive a more detailed impression, visit the demo page.
For facilities with installations of Nexperion Sentinel on multiple microscopes, a “Systems Overview” feature is available, providing the most important details of all instruments at a glance. An example with two systems can be found at our demo page.
Nexperion Sentinel’s logging facility records events and microscope parameters such as vacuum levels, high tension, or user logins to text files readable with any spreadsheet application. Reviewing historical data can facilitate an understanding of where issues started or how they evolved over longer periods of time or may be used for user logging.
Depending on the version of Sentinel, the configuration of the specific instrument, and the options ordered with Sentinel, more or fewer options than depicted in these screenshots are available.
Nexperion Sentinel is available for the FEI Tecnai, Titan, and Talos platforms with the TEM Scripting Adapter as well as for JEOL TEMCON and TEMCENTER based microscopes. Please inquire for more detailed configuration requirements and other instruments.
For connection with external sensors (environment, chillers), one or more free USB ports are required. For remote notification and the Internet status page, a possibility to set up an Internet connection (e.g. via port forwarding) is required.
