Ethernet thermometer and data logger with alert functionality

Querx PT1000 is a small sized network thermometer for measuring, recording and monitoring temperature data over Ethernet. Modbus/TCP and SNMP allow to transmit the collected data to network management and industrial process monitoring systems (SCADA). Furthermore, the data can be exported to the Internet-of-Things clouds ThingSpeak and Xively is hence world wide accessible. With the application programming interfaces provided by the cloud services, it is easy to integrate Querx PT1000 into own projects. If the device measures critical values, alerts are sent out over email, SNMP trap and syslog message.

Any Pt1000 probes – Many fields of application

Pt100-AnschlussQuerx PT1000 can be used with any 2-, 3- or 4-wire Pt1000 temperature sensor. So the device is suitable for countless use cases, depending on the used sensor. In combination with a screw-in-probe, you can for example measure the temperature within pipelines. Food-safe probes allow monitoring of refrigeration units. A multitude of vendors offer a wide choice of sensors fitting into your particular use case.

Alert functionality

If configurable conditions are met, Querx PT1000 triggers alerts. SNMP traps and syslog inform network management systems, the StartTLS email interface sends notifications to up to 4 recipients. Besides on exceeding temperature limits, Querx PT1000 can trigger alarms if temperature rises or drops too fast.

Data logger

Querx PT1000 records maximum, minimum and average values of at least 51 days in a one minute interval. The values are depicted in a convenient web interface and can be embedded into other websites using Iframes.

Manifold interfaces for data access

Besides the web interface, over which you can access the recorded data as interactive chart and export it as CSV and XML, Querx PT1000 provides many interfaces for requesting currently measured and recorded data.

SNMP allows integration into IT monitoring systems
Modbus/TCP allows integration into industrial process managament systems (SCADA)
Cloud interfaces allow worldwide data access over web and application
The HTTP interfaces (XML, CSV and JSON) allows easy integration of current and recorded data into own projects
Extensive documentation and application focused support

The user manual provides detailed information on configuration, operation and data access. On the product website you can find many step-by-step tutorials on how to use Querx PT1000 in specific use cases, most of them being a by-product of our product support and made in cooperation with our customers.

DAkkS calibration certificates available

For applications in the area of quality management it is possible to ship the sensor with an additional DAkkS calibration certificate. That is, in cooperation with our accredited partner laboratory, the sensor is put into relation to the German national measurement standard.
