Power Line Meter
-
The Line EMI Meter measures electromagnetic interference in a single-phase AC power line. It plugs into a wall outlet (mains socket) and requires no battery. It immediately displays total line noise in millivolts (range 1999 mV, resolution 1 mV) in the frequency range 10 KHz 10 MHz (the frequency limits at which sensitivity is of the maximum sensitivity). A speaker plays the sound of the EMI, amplitude demodulated, in order to identify the EMI source (such as an AM or shortwave radio station vs. a motor vs. an electric arc).

Air Core Line & Load Reactors
-
Line and load reactors are generally serial-connected to the input and/or output terminals of three phase equipment such as motor speed controllers, inverters and UPS systems. These equipment make use of semiconductor switches such as IGBTs, thyristors, and diodes and therefore create harmonic distortion and high switching over-voltages (dv/dt). Use of such equipment has been becoming more widespread as the technology advances. However, the negative effects of these equipment should not be overlooked.

Time Delay and Integration (TDI) Line Scan Camera
Piranha HS
-
The Piranha HS cameras provide an alternative to traditional line scan imaging. They enable you to meet the line rates and responsivity necessary for your high performance applications and allow you to reduce the number of cameras in your system. When you use fewer cameras, you use fewer framegrabbers, lenses, computers and cables. The Piranha HS family delivers the lowest price/pixel TDI system solution ever offered by Teledyne DALSA. Lighting costs can also be reduced. With TDI imaging, you can use LED lights, helping you to optimize system up-time and productivity.
