The Model 81094 is the first in a series of Internet/Intranet accessible Advanced Wattchman® Wattmeter/Alarm systems that will monitor both forward and reflected power in two transmission lines with only one controller.  Unlike previously available systems that needed one controller for each transmission line, the Advanced Wattchman® will monitor two lines (4 ports).  The front panel display shows power on both systems simultaneously.  Operating conditions may also be displayed on a PC from any location on the Internet/Intranet.

The Model 81094 is designed to work with a series of specialized line sections from 7/8” to 6-1/8” and standard Coaxial Dynamics elements for either analog or digital applications.  Elements are available from 1 W to 100 kW and from 2 MHz to 2.3 GHz.

A typical system normally consists of an Advanced Wattchman® controller and a dual socket line section with the appropriate elements for each transmission line to be monitored.  Each line section comes with a 10-foot telecommunications style cable to interface with the 81094.  No additional power supply or cabling is required at the line section other than an RF source and load.

Abnormal load conditions quickly cause an alarm and email notification.  Each transmission line may have entirely different power levels and frequencies since those parameters are determined by the elements.  Different alarm/shutdown requirements can be set for each transmission line.

By accessing the controller through the RJ-45 connector on the rear panel alarm levels, power ranges for the elements as well as email notification of fault conditions may be set.

Three sets of interlock terminals are available on the rear panel.  One set of terminals will be activated with any fault; the other two sets are for each individual system.  An audio alarm will sound for any fault conditions.

Your confidence in the quality and dependability of the Model 81094 Wattmeter is assured with the Coaxial Dynamics Two Year Limited Warranty.
