  • Near Field Probes 30 MHz up to 3 GHz

    RF2 set - Langer EMV-Technik GmbH

    The RF2 near field probe set consists of 4 passive near field probes for measurements in the development phase of the magnetic field in the range from 30 MHz to 3 GHz on electronic assemblies. The probe heads of the RF2 set allow the step by step localization of interference sources of the RF magnetic field on assemblies. From greater distances the electromagnetic interference can be detected by RF-R 400-1 and RF-R 50-1 probes. The RF-B 3-2 and RF-U 5-2 probes with their higher resolution can more precisely detect the interference sources. Field orientation and field distribution on an electronic assembly can be detected through a trained special use of the near field probe. The near field probes are small and handy. They have a sheath current attenuation and are electrically shielded. They can be connected to a spectrum analyzer or an oscilloscope with a 50 Ω input. They do not have an internal terminating resistance.

  • Near Field Probes 30 MHz up to 3 GHz

    RF6 set - Langer EMV-Technik GmbH

    The RF6 near field probe set consists of 2 passive magnetic field probes and 2 passive E field probes for measurements in the development phase of the E-field and magnetic field in the range from 30 MHz to 3 GHz on electronic assemblies. The probe heads of the RF6 set allow a step by step localization of interference sources of the RF magnetic field and RF-E-field on an assembly. From a larger distance the electromagnetic interference is detected by RF-R 50-1 for the magnetic field and by RF-E 02 for the E-field. The RF-B 3-2 and RF-E 10 probes with their higher resolution can more presicely detect the interference sources of the magnetic field and the E-field. Field orientation and field distribution on an electronic assembly can be detected by special guidiance of the near field probe. The near field probes are small and handy. They have a sheath current attenuation and are electrically shielded. They can be connected to a spectrum analyzer or an oscilloscope with a 50 Ω input. They do not have an internal terminating resistance.

  • Duct Type Wind Speed Sensor

    WSA - Chuan Sheng Electronics Co., Ltd.

    Due to environmental quality management and energy management, we've developed WSA, wind speed sensors which can be applied on ventilation systems, air conditioning, and negative pressure rooms. WSA is a high-accuracy duct type wind speed sensor which can quickly measure the small wind speed. It is stable, high-accurate, and with small drift only. Also, it can caculate the value of the current air volume depending on the measured cross-sectional area of the ducting. Ducting installation and screwless terminals help the users work more easily. Besides, the sensor is equipped with EMC anti-interference devices so that it can withstand strong electromagnetic interferences.

  • Preamplifiers

    Com-Power Corporation

    Com-Power broadband high gain preamplifiers were designed for electromagnetic interference (EMI) testing and certification. EMC test labs use preamplifiers to improve sensitivity of the test system during EMI radiated emissions measurements. Without a high gain preamplifier, signals picked by the antenna that have amplitudes below the noise floor of the test system cannot be measured. The preamplifier gain has minimum variations for the entire operating frequency range for accurate emissions measurements. The Com-Power preamplifiers were primarily intended for EMC applications. However, it can be used for other applications that require signal amplification.

  • Capacitive Proximity Sensors

    SICK Sensor Intelligence

    Sometimes you need to know what is hidden beneath a surface. Behind a wall, for example, inside a storage container, inside a shipping container, or behind a cover. Capacitive proximity sensors are ideal for level and feed monitoring. From solid material, such as paper or wood, to granules or liquids, they can be relied upon to detect what is happening in the production process and during final inspection. Is there something behind that cover? Is the finished package really full? How much paint is still left in the tank? For capacitive proximity sensors, these are easy questions to answer. SICKs capacitive proximity sensors are never far from the action. Sensing ranges between 1 and 25 mm allow them to be used in nearly all installation situations, making them extremely adaptable for a wide range of applications. These sensors are also remarkably resistant to interference. Impurities, contamination, dust, and airborne spray particles have little effect on them, nor does electromagnetic interference. No wonder they are installed in a wide range of industries, such as food and automotive, or in storage and conveyor systems.
