Reliable Data Logging

Querx PT measures the temperature via external Pt100 / Pt1000 sensors and makes all the data available via LAN.
The minimal, maximal and average values are stored on the device at one minute intervals, including a timestamp. The integrated storage can hold the data of at least 51 days and all data is safe even in the event of a power shortage.

Data Visualization

The web interface visualizes all gathered data in an interactive graph. Modern technology standards such as HTML5, CSS3 and SVG facilitate data access via the web browser on your computer, tablet or smartphone.

Data Export in Various File Formats

Querx PT can export data, making further processing and archiving simple. The CSV format is suited for spreadsheet software such as Excel. The XML format enables further automated processing in customized software solutions.

Suitable for Monitoring Systems

The data is provided via M2M systems. The sensor can be integrated into network management systems such as Zabbix or Icinga via SNMP. Modbus/TCP allows to use the device in the industrial sector via SCADA. All logged and current data can be accessed from Python, PHP and other programming languages via HTTP.

Cloud Interfaces

If required, all data can be sent to Internet-Of-Things clouds such as ThingSpeak or dweet.io. This feature makes it possible to access data around the globe and integrate all data into custom projects via the programming interfaces provided by the cloud services.

Diverse Alerts

Querx PT send emails, SNMP traps and Syslog messages to notify you when
- 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

Up to four recipients can be informed of any occurring alerts via two mail servers. Notifications can therefore be sent even if one server should fail.
The alert emails are encrypted. Customizable text-variables let you create meaningful notifications.

Simple Operation via Web Interface

Configuring and operating Querx THP is intuitive. The user interface is self-explanatory and additionally features an in-depth online help section.

Quick Setup

Integrating the smart sensor into existing networks requires no complicated configuration. It supports mDNS / Bonjour, allowing for automatic detection and DHCP network configuration.

Extensive Selection of Sensors

Querx PT supports any 2-. 3- and 4- wire Pt100 or Pt1000 temperature sensors.
Temperatures in the range of -328 °F to +1382 °F (-200 °C to +750°C) can be measured, depending on the connected sensor. This makes the device suited to a wide field of applications.

Accredited Calibration upon Request

Calibration is a vital component of quality control. DAkkS certificates (German accreditation body) are available for all Querx devices. They can be purchased together with the device or at a later date.

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.

Extended Temperature Range

The smart sensor works reliably, even in adverse conditions. Querx TH functions in temperatures between -40 °F and +185 °F (-40 °C and +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 wall plug power supply can be used to power the device.

Always up to Date

The Querx firmware is continually updated and adapted to current developments. New versions of the firmware are made available periodically. The web interface tells you what version Querx is currently running and lets you update the firmware.

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.
