Web Thermometer UV 2x

Log & report measurements at the sub-distribution panel

The Web Thermometer UV 2x measures two temperatures and makes the values available in the network. The sub-distribution panel design, the integrated data logger and numerous web and network services enable easy integration of building management systems and IoT applications.

Properties

Sensor:

  • Two measurement inputs Pt100/Pt1000:
    • Measuring input, each: -200°C...650°C
    • Measuring range with W&T probe (1x included): -50°C...180°C

Connectivity:

  • Intuitive Web interface for simpler configuration
  • Monitor temperatures and trends from a browser
  • Alarm and reporting function:
    • E-mail for alarm or reporting functions
    • SNMP polling / alarm traps
    • Configure up to 12 alarm messages
  • Dynamic integration into other Web sites:
    • Direct access to current measurement values, e.g. JavaScript (AJAX).
  • Current Industry 4.0 protocols:
    • OPC UA, REST and MQTT support
  • Supports enhanced security requirements
  • Additional software interfaces for incorporating into your systems/databases:
    • SNMPv1, SNMPv2c, SNMPv3
    • Modbus-TCP
    • OPC UA, OPC DA
    • Syslog
    • Sensobase (database integration via ODBC)
