Querx WLAN PT
Pt100 / Pt1000 WiFi Thermometer and Data Logger
Querx WLAN PT measures the temperature via external Pt100 / Pt1000 cable temperature sensors and makes all the data available via LAN or WiFi.
The smart sensor features an integrated data logger, alert functions and several interfaces for manual or automated data access.
The autonomous device is configured and controlled via a graphic web interface.
Querx WLAN PT supports various cloud providers. This makes it possible to access data via web, app or API from anywhere and at any time.



Features
[-]
Reliable Data Logging
Querx WLAN PT measures the temperature via external Pt100 / Pt1000 sensors and makes all the data available via LAN or WiFi.
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 7.5 years 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 WLAN 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 dweet.io, Palamoa or ThingSpeak. 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 WLAN PT sends emails, SNMP traps and Syslog notifications and also features optical and acoustic alerts that are triggered when - the temperature rises above or falls below configurable limits - the temperature rises or fall 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 WLAN PT 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 or LLMNR, allowing for automatic detection and DHCP network configuration.
Extensive Selection of Sensors
Querx WLAN 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. ISO or DAkkS certificates are available for all Querx devices. They can be purchased together with the device or at a later date.
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 WLAN 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.
