Central Office Line Simulator
AI-7280
-
The AI-7280 is a highly flexible central office line simulator. It is designed primarily for the testing and verification of common terminal equipment, including standard telephones, Caller ID devices, SMS (Short Message Service) capable equipment, and any device using an analog Tip/Ring interface circuit. Supplied with the TRsSim software for Windows, it can analyze a telephone''s DTMF characteristics, pulse dialing and flash timing, generate various network tones and ringing patterns. Both Type I (on-hook) and Type II (off-hook) Caller ID is supported using either FSK or DTMF data transmission. As an optional component, the TRsSim software can perform SMS testing to either the ETSI protocol 1 or protocol 2 standards.

AC Power Line EMI Filters
CleanSweep®
-
CleanSweep® filters block EMI on power lines (both common and differential modes) and, uniquely, in ground, from reaching sensitive equipment. They also reduce EMI "backflow" from a "noisy" source that otherwise would end up on your AC power network.

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).

Lining Thickness Measurement
-
ElektroPhysik Dr. Steingroever GmbH & Co. KG
Measuring the lining thickness of rotary kilns is an important process in the industry, especially in cement production. The lining of a rotary kiln consists of refractory material that has to withstand high temperatures and chemical stresses to ensure a smooth production process. The thickness of the lining is of great importance because it has a direct influence on the efficiency, safety and service life of the rotary kiln. Measuring the lining thickness is therefore an important and fundamental aspect when it comes to the safety of rotary kilns.
