Web-Thermograph 2x

  • Web-Thermograph 2x

Measure, log and report...

The Web-Thermograph 2x is an instrument that measures two temperatures and makes the values available in the network. The device includes an integrated data logger and numerous Web and network services for manual querying of the measurements or provides autonomous sending of messages.

Properties

Sensor:

  • Two temperature inputs Pt100/Pt1000:
    • Measuring range of W&T probe: -50°C...180°C
    • Measuring input: -200°C...650°C

Connectivity:

  • Monitor temperatures and curves with your browser
  • Alarm and reporting function:
    • E mail for alarm or as reporting function
    • SNMP polling / alarm traps
    • Up to 8 alarm messages can be configured
  • Dynamic integration into other Web sites:
    • Direct access to current measurement values via AJAX, JavaScript and Java applet
  • Additional software interfaces for incorporating into your systems/databases:
    • OPC server
    • Syslog
    • Sensobase (database integration via ODBC)
    • TCP and UDP sockets, client and server
    • FTP (data logging)
  • Possible applications:
    • Monitor temperatures in the server room, network cabinet or office
    • Direct display of multiple measuring points in the browser via Java applet
    • Logging of measurements via FTP, Excel file, email attachment and internal memory
