  • NITOS Wireless Sensor Platform

    NIT Laboratory

    The NITOS prototype wireless sensor mote, is comprised of open-source and configurable modules. NITOS mote features the ATmega32u4 microcontroller running at 8MHz and operating at 3.3V. The aforementioned microcontroller is fully compatible with the Arduino platform that enables ease of software development and provides compatibility with several commercial sensing modules. Moreover, the platform is equipped with an Xbee radio interface that enables communication with the respective gateway. The Xbee module is a tiny device ideal for setting up mesh networks and has a defined rate of 250 kbps. This module uses the IEEE 802.15.4 stack which is the basis for theZigbee protocol. Apart from the Xbee module, NITOS mote can also feature a WiFi wireless interface in order to communicate with WiFi gateways. The developed mote currently features specific sensing modules, an air temperature and humidity sensor, a light intensity sensor and a human presencesensor. Various types of sensing modules and actuators can be further integrated exploiting existing Arduino software that implements several existing communications protocols. The firmware can be easily uploaded through the on-board USB connection. Figure 1 illustrates the developed NITOS mote and the respective gateway node.

  • WIreless Controller

    Site Sentinel CXT - Teledyne Gas & Flame Detection

    ​Command functions include alarm reset, alarm acknowledge, alarm test and radio silence. In normal operation the control panel provides real time display of gas concentrations or the status of other field devices; battery charge levels, network RF signal quality and any number of fault diagnostic conditions affecting either an individual field device or the entire network. These fault conditions are displayed on the control screen.Options include audio alarm, visual alarm, external alarm port, alarm reset switch and up to 4 external wired sensor inputs. Standard features include a power-in port and power switch.The control panel is rated for Class 1, Division 2; Groups A, B, C, D hazardous areas. Operator interface is non-intrusive via magnetic contact switches located behind the glass lens cover. This advanced design takes advantage of a low power LCD with back light and ultra low power components. Power is provided by an internal rechargeable battery and/or 11.5 to 30VDC. Operating time is 1-2 months before recharge is required. An optional solar charging panel can be used to extend operating time for virtually any application.

  • Frequency Converter Upwards

    UPCONVERTER 10 GHz LXI - Holding Informtest

    UPCONVERTER 10 GHz осуществляет программно управляемый перенос вверх спектра шириной 150 МГц, поступающего на вход сигнала, в любую точку спектрального диапазона от 10 МГц до 10 ГГц. Перенос спектра осуществляется по супергетеродинному принципу с тремя ступенями переноса. Благодаря этому во всем рабочем диапазоне спектра достигаются высокие уровни подавления несущей частоты и зеркального канала. Также UPCONVERTER 10 GHz обладает уникальной возможностью, не имеющей аналогов среди приборов подобного типа – задавать значение промежуточной частоты (входного сигнала) для переноса в диапазоне от 50 до 400 МГц. Помимо этого, прибор позволяет передавать входной сигнал частотой от 0,1 до 400 МГц напрямую на выход, без переноса. Благодаря этому, совместно с UPCONVERTER 10 GHz в качестве генератора промежуточной частоты может быть использован широкий спектр генераторов зарубежного и отечественного производства. Холдинг «Информтест» предлагает потребителям генераторы собственной разработки MGKS and MGVCh , as well as the first Russian MT transceiver module , which are fully compatible with the input characteristics of UPCONVERTER 10 GHz. Together with generators produced by the holding "Informtest" UPCONVERTER 10 GHz under the control of a common software shell makes up a synthetic instrument - a ready-made solution for testing microwave devices and radio reception channels.

  • Battery Capacity Tester

    BLU-T Series - IBEKO Power AB

    Battery load bank BLU-T is a powerful and lightweight solution designed for condition assessment of telecommunication and radio equipment backup supply. This instrument can perform the battery capacity test on battery strings such as Pb, Li-ion, Ni-Cd, and others. It tests battery strings with voltages in the range of 0,9 – 70,5 V DC. As a special feature, the BLU110T model enables capacity testing of single PB, Ni-based as well as Li cells (with current up to 100 A).The capacity test is conducted in an accurate, user-friendly way. Also, it is in accordance with battery testing standards: IEEE 450-2010, IEEE 1188-2005, IEEE 1106-2015, IEC 60896-11/22, and other relevant standards.BLU-T battery load bank enables setting the discharge current up to 350 A, with 0,1 A resolution. If higher currents are required, the BLU-T units can be connected in parallel, or BXL-T additional load units can be linked.The instrument offers a high power-to-weight ratio. BLU-T series has models starting from 12,8 kg / 28.2 lbs and up to 19,2 kW of power.A user can select one of three discharge modes: Constant current, Constant power, Constant resistance. Additionally, different battery duty cycles can be simulated using user-selectable discharge profiles.Discharge parameters can be monitored in real-time during the capacity test. A 4,3-inch touch screen shows overall battery voltage, discharge current, discharge test time and capacity during the entire test. Also, the capacity tester is compatible with DV-B Win software. A user can view a detailed numerical and graphical presentation of key parameters, and create reports in various formats.Testing can be carried out without disconnecting the battery from the service.
