  • Cable Tester, Tracer, Tone Generator, Network tester

    PR-68 TestAll - Pansco, Ltd

    The Testall is an attempt to put together in a small package all the features a professional or amateur working with network cables might need. The first is a pin-by-pin cable tester that displays results on a remote terminator and can run automatic and manual tests. The second is a tone generator with a normal frequency signal and a high frequency signal for tracing twisted pair, coax and telephone cables, (the tone probe, a separate unit, is included), the third is a network test mode, which detects network activity and speed and forces the port light of the cable it is plugged to blink, so you can identify it. A few other capabilities round out the package: a cable continuity test, a polarity test, an over current indicator and a battery-low warning LED to prevent misreading due to battery failure.

  • Cassegrain Antennas

    Sage Millimeter, Inc.

    Cassegrain antennas are offered with a 6”, 12”, 18”, 24”, 36” and 48” diameter main reflector dish. These antennas are designed and manufactured with the highest performance and quality. The main advantages of the Cassegrain antenna are its low loss, low profile and light weight compared to other high gain antennas, such as prime focus and lens corrected antennas. As a downside, this antenna has relatively high side lobe levels compared to other antennas due to the interference of the sub-reflector’s supporting structure. To ensure good performance, the supporting structures are specially designed to keep side lobe levels under 18 dB for narrow band operations and under 16 dB for broadband operation. The standard offering covers the frequency range of 18 to 110 GHz, but custom frequencies can be requested. The operating bandwidth of these antennas is mainly limited by the circular waveguide’s dominant mode operation. While standard models are equipped with a circular waveguide interface, a rectangular waveguide interface is also available.

  • Photolytic True NO2/NO/NOx Analyzer

    Model T200P - Teledyne Advanced Pollution Instrumentation

    The Model T200P provides measurements of NO and NO2 using our Model T200 NOx analyzer combined with a patented high efficiency photolytic converter. Even low temperature molybdenum converters transform other nitrogen-containing compounds such as HNO3, PAN, etc. to a considerable extent. Simultaneous measurements of NO2 performed with molybdenum and photolytic converters have shown significantly different results in the presence of such compounds.In the photolytic process the sample gas passes through a cell where it is exposed to light at a specific wavelength from an LED array. This causes the NO2 to be selectively converted to NO with negligible interference from other gases. Advances in the photolytic converter technology now yields NO2 conversion efficiency that is similar to molybdenum under typical ambient NO2 concentrations, but without the same interferences.

  • PLC Controller

    Ajinkya Electronic Systems

    We are also engaged in manufacturing PLC Controllers. Our plc controllers has dedicated Logic, They are used for industrial process control systems, they are also called as Programmable Logic Controller, PLC or Programmable Controller is a digital computers used for automation of electromachanical processes, such as control of machinery on factory amusement rides, or light fixtures. PLCs are used in many industries and machines. Unlike general-purpose computers, the PLC is designed for multiple inputs and output arrangements, extended temperature ranges, immunity to electrical noise, and resistance to vibration and impact. Programs to control machine operation are typically stored in battery-backed-up or non volatile memory. A PLC is an example of a hard real time system since output results must be produced in response to input conditions within a limited time, otherwise unintended operation will result.

  • 6000 Series Digital I/O Modules

    Pacific Instruments, Inc.

    Series 6000 digital I/O modules record signals from frequency counters, flow meters, encoders, discrete transducers, IRIG time, etc. which are often part of the test environment. These digital signals are time aligned and recorded alongside the system’s analog measurements. High density digital inputs provide an opportunity to easily include facility controls like switches, valve positions, relays, lights, etc. along with the test data. Series 6000 digital I/O modules also provide outputs generated by user command or automatically by Sequence, Alarms or DSP. User generated outputs are accomplished in software while sequencers can be programmed prior to a test and initiated by program or hardware control. Alarm conditions preprogrammed on the analog side can automatically generate digital outputs which are typically connected to facility control systems or PLCs. A DSP adds powerful real-time processing and is appropriate for PID control loops, derived parameter calculations and a variety of other real-time operations.
