Testing & measuring

Testing LAN, telecom, umbilical and coaxial cables DCM provides test and measurement solutions for quality assurance testing of all types of twisted pair and coaxial cables. Test parameters include crosstalk, impedance, insertion loss (attenuation), VSWR, capacitance, resistance, return loss and SRL. LAN cable test solutions covering Cat 5e, Cat 6, augmented Cat 6 and Cat 7 cables up to 1.5 GHz include: Model SCS-350B bench-top system • for Cat 5e and Cat 6 cables Model CMS-2XLD integrated system • for Cat 5e, Cat6A and Cat 7, including 6-around-1 alien crosstalk and power sums Model ES-2G bench-top system for • Cat 7 cables RF and coaxial cable test solutions cover all types of coaxial cables for 50-ohm and 75-ohm cables, for 3G to aerospace applications. Test frequencies range from 3 GHz up to 40 GHz. Telecom cable test solutions cover all types of twisted pair telecom cables with test fixtures up to 102 pairs. LF para- meters include capacitance, resistance and cable unbalances. HF parameters include crosstalk and attenuation, as well as xDSL applications up to 100 MHz.

FMS Force Measuring Systems launches its newest RTM (radio transmitted tension monitoring) system. Through continuous development work on the RTM System, wire and cable manufacturers now have an affordable way to monitor and control tension in individual wires on most planetary or tube stranders, bunchers, twisters, or other rotating machinery. The RTM system monitors tension in real time on up to 32 individual strands, and can be configured to handle nearly any tension measurement or control task. Actual tension values are displayed graphically on a PC monitor and logged for possible quality assurance reference. The monitoring system is comprised of tension sensors, tension measuring amplifiers, a bus system with radio transceivers, a control unit and software. Tension control in individual wire strands

Compression tester Easydur Italiana offers an automatic machine for the testing of compression springs. The unit can be combined with a vibrator element, a pressing system (up to 10,000N) with up to three independent hydraulic pistons (adjustable for height and pressure), an image analysis camera, chamfer control station, spring tester for load and/ or position measurement (up to 5,000N), and a sorting system with five tolerance settings. Easydur Italiana – Italy Fax : +39 0332 206710 Email : info@easydur.com Website : www.easydur.com In applications where closed loop tension control is desired, digital tension controllers are integrated into the system. Controller parameters, including tension set points, can be adjusted during machine operation. Possible configurations include the capability to provide a high-/low-tension alarm signal, or an output to stop the machine immediately in the case of a wire break. The FMS tension sensors are specially designed for rotating applications, and are compensated for both centrifugal and Coriolis forces to very high accelerations. A wide range of tension sensors is available to suit almost any application. With the standard data logging feature, the RTM system will record the tension value of each strand correlated to the product running length. The RTM system is designed to be reliable, accurate, economical, easy to operate, and virtually maintenance-free.
