Since 1954, Lumel has been recognized for producing quality measuring and panel instruments within automation, electrical quality, and energy optimization. The products are manufactured in Europe and are based on continuous development and focus on quality and functionality
ND45 power network
The ULT20 is designed to measure distance/level, and after programming functions which process the measured value of distance, it can be used to measure the filling of tanks, to count the flow and level measurement in open channels.
Built-in LCD display, which, together with the buttons creates a local user-friendly interface, allows for any change of operating parameters and viewing the current status of the device, including the reading of measured values.
HT20IoT klima datalogger
It enables quick, easy, and convenient installation of dedicated 1- and 3-phase current transformers and additionally eliminates the risk of a faulty connection of a meter with the transformers.
It provides a perfect solution for controlling and monitoring of parameters regarding the energy quality and on top of that it enables controlling and optimisation of functioning of various power electronic devices, systems, and industrial installations.
Current inputs 0.1A and 0.25A (for dedicated transformers), quick and convenient ways to connect current transformers via RJ12 connector or screw terminals, THD factor measurement, digital transmission to the master system through the RS-485 interface (MODBUS RTU).
NA6 plus digital display
The ND45 Power Network Analyzer measures and records over 500 electric energy quality parameters, class A for selected parameters, harmonics and interharmonics up to 51st, energy measurement in 4 tariffs, recording of measurements before and after events (dips and swells), configurable display and web server, Supports Modbus Slave, Ethernet 100 Base-t and USB - these are only some of the ND45 power analyser advantages.
ULT20 niveau sensor til lukkede systemer og åbne kanaler
The HT20IoT data logger has been designed to measure, monitor, and record temperature and humidity. It is a perfect solution for any facilities where monitoring and recording such values are very important for the accuracy of the whole process e.g.: in server rooms, drug and food warehouses, laboratories, museums, or glasshouses.
The data captured by HT20IoT is stored in the internal memory and then sent digitally to the user (by the Ethernet MQTT).
In case of an emergency, the device immediately sends appropriate warnings via emails or via a website.
With the new version of datalogger HT22IoT Invironmental Parameter Monitor we can now monitor temperature, humidity, light intensity, CO2 concentration and TVOC (total volatile organic compounds in the air)
ND20ct power network
NA5- and NA6PLUS meters with bar graph are devices ensuring both a high measurement accuracy and very well visualization of the measuring process courses. Very well visualization of the process is possible through using in meters 3 and 7-coloured bar graph built with diodes made in the gallium nitride technology. They can find application in various industrial fields, e.g. food industry, pumping stations and savage-treatment plants, chemical industry, weather stations, brewing industry and many other fields where they are destined for visualisation of the measured value and evaluation of the monitored manufacturing process change trend. They can also find application in automation systems where programmable controllers are applied.
