  • TEM Cells

    Tescom Co., Ltd.

    TEM (Transverse Electromagnetic) Cell is a device for generating a broadband standard electric field and measuring radiation power. It was developed in the 1970s by U.S. NBS Lab and is now used widely for EMI/EMS tests and more. When a user applys the RF test signal into the TEM Cell, a plain wave is generated inside. This measures the value of the path loss up to the DUT (Device Under Test) and examines the reaction of the DUT. Even when repeating the measurement, the TEM Cell maintains a constant path loss value with regard to the same test signal and same DUT location. Hence, it can be used for an OTA (Over The Air) measurement of wireless handsets.

  • Combination Wave/Surge Generators

    EM Test

    Surge pulses occur due to direct or indirect lightning strokes to an external (outdoor) circuit. This leads to currents or electromagnetic fields causing high voltage or current transients. Another source for surge pulses are switching transients originating from switching disturbances and systems faults.Due to the characteristic of the phenomenon nearly every electrical and electronical device may suffer from such lightning events which justifies the necessity of surge tests being widely performed. Surge voltage can reach several thousands of volts and surge current is seen to reach several thousands of amps.EM TEST offers a wide range of Combination Wave generators with different output voltage ranges for various test requirements:

  • TEM Antenna

    Techimp HQ S.r.L

    TEM antenna is a partial discharge sensor designed to receive electromagnetic (EM) emissions from a PD occurring in the monitored asset (like MV switchgears or LV and MV induction motors fed by power electronic impulses). It is a broadband antenna with a flat response which makes TEM suitable in a number of different applications. It has been optimized to operate in a frequency range typical for PD activity and it was designed to provide maximum sensitivity and high gain. Its compact and robust design (passive sensor) makes TEM the optimal sensor for direct installation on medium voltage Switchgears and motors. It can be virtually applied in any electrical equipment provided that it has apertures or EM transparent surfaces.

  • Resistive & Inductive AC Load Bank

    RL - Junxy Energy

    Resistive & reactive load banks are able mimic motor loads and electromagnetic devices within a power system as well as purely resistive loads by offering the ability to set a specific power factor (pf). Many backup generators and turbines are rated at 0.7, 0.8 or 0.85 power factor and need to be commissioned at nameplate capacity using a combination of resistive and reactive load to fully qualify their operating capability. Using a resistive & reactive load bank enables comprehensive testing from a single unit. JUNXY has an extensive range of resistive & reactive load banks to simulate these types of loads on a power source and the transformers, relays, and switches which will distribute the power throughout your facility.

  • EM Explorer

    EM Explorer

    EM Explorer is a 3D electromagnetic (EM) solver for scattering problems of periodic structures illuminated by arbitrary incident fields including planewaves, Gaussian beams and focused Hi-NA beams. It can simulate both complex dielectric and complex magnetic materials including left-handed materials (LHM) that have a negative refractive index. EM Explorer is largely based on the same method of Finite Difference Time Domain (FDTD). Therefore it inherits most of FDTD's advantages and disadvantages. The advantages include simple & robust numerical algorithm, versatility for nearly any geometries, and good scalability of computing resources as a function of simulation volume size. The disadvantages are numerical dispersion and stability constraint due to the finite difference (FD) approximation to Maxwell's equations and explicit time marching algorithm.

  • Radar Level Gauge

    HRRD730 Series - HighReach Measuring & Controlling System Co.,Ltd

    At The Radar Level gauge Antenna emits and Narrows at The Microwave Pulse. This Pulse propagates in Space AT at The Speed of Light. The When IT Encounters at The Surface of at The the Measured Medium, Part of the ITS Energy IS the REFLECTED the Back and Received by at The Same, Antenna. At The Time interval The Between the transmitted pulse and the received pulse is proportional to the distance from the antenna to the surface of the measured medium.Because the electromagnetic wave propagation speed is extremely high, the time interval between the transmitted pulse and the received pulse is very small (on the order of nanoseconds). It is difficult to confirm. The 90X series 26G radar level gauge uses a special demodulation technology To accurately identify the transmitted pulse and the time interval of the pulse is received to further calculate the distance of the antenna from the surface of the measured medium.
