Reliable Data Tracking

Querx PT measures the temperature via external Pt100 / Pt1000 sensors. All data can be accessed via LAN.

Continuous Data Logging

The smart sensor saves the measured values once a minute. The minimum, maximum and average values are saved with a timestamp for at least 51 days and will not be lost, even if a power shortage occurs.

Interactive Data Visualization

The web interface displays all tracked measurements in an interactive graph. The latest standards such as HTML5, CSS3 and SVG facilitate access to the interface via your PC, tablet or smartphone.

Data Export in Several Formats

Recorded measurements can be exported for further external processing and archiving. The CSV format is compatible with spreadsheet applications such as Excel. The XML format makes it possible to process data automatically in customized software solutions.

System Monitoring

Querx PT provides access to data via M2M-interfaces. SNMP support lets you integrate the sensor into network management systems such as Zabbix or Icinga. The device can also be applied in the industrial sector via SCADA systems, due to the integrated Modbus/TCP interface.

Data Access via HTTP

All current and logged values can be retrieved in the XML, JSON and CSV file formats. This makes them accessible from the command bar and via Python, PHP or other programming languages.

Cloud Connectivity

If required, all data can be transmitted to the Internet of Things services ThingSpeak and Xively. This lets you access your data globally and facilitates the integration into custom software systems via the interfaces provided by the cloud services.

Various Alerts

Querx PT can send emails, SNMP traps and Syslog messages to notify you if
- the temperature rises above or falls below configurable limits
- the temperature rises or falls exceptionally quickly
- the value returns to its normal range

Encrypted Email Alerts

Querx PT can notify up to four recipients of occurring alerts using two discrete email accounts. This ensures that alert notifications are sent even if one server fails.
The emails are encrypted. Messages can be customized with text-variables, making them easily comprehensible.

Intuitive Operation via Web-Interface

Configuring and operating Querx PT is an intuitive process. The user interface is self-explanatory and a detailed online help section is also provided.

Quick Setup

Querx PT can be integrated into existing networks without any configuration being required. The smart sensor can be detected automatically by mDNS / Bonjour and it can be configured automatically via DHCP.

Extensive Selection of Sensors

Querx PT supports any 2-. 3- or 4- wire Pt100 or Pt1000 temperature sensors.
Temperatures in the range of -328 °F to 1382 °F can be measured, depending on the connected sensor. This makes the device suited to a wide field of applications.

Easy installation

The case's small footprint makes it possible to install the sensor in confined spaces. It can be fastened easily by using the slits on the casing.

Accredited Calibration Available

Calibration is an integral part of quality control. DAkkS-certification (German Accreditation Body) is available for Querx devices for a service-fee when purchasing the product or at a later date.

Extended Temperature Range

Querx PT works reliably even in unfavourable conditions. The smart sensor can operate at temperatures between -40 °F and 185 °F (-40 °C - 85 °C).

Low Power Consumption

Querx PT is very efficient. The power consumption is less than 1 W. An unused USB port or an external EU power adapter can be used to power the device.

Always up to Date

The Querx firmware is in continuous development and new functionality is frequently added. New versions are uploaded to the web periodically. You can determine which version your device is running and initiate an update right from the web interface.

Querx PT’s Sensor Cable Connector Has Changed

28. May 2017

Up until now, the Querx PT models’ pair of two-wire connectors, into which the wire sensor cables are clamped, were stacked vertically. From version 1.1 on, the four screw-terminals are placed side by side so the individual wire ends can be easily secured with a flat-tip screwdriver.
