All-in-one measurement station

Depending on the application, sensors can be used for object measurement as well as for objection detection. The Leuze LSC 200 is a complete system, or all-in-one measurement station, and is suited to applications in intralogistics and packaging operations where sensors and evaluation units are optimally matched to one another. Pre-installed software on the evaluation unit performs data

Controller improves high speed accuracy and performance Manufacturers are under constant pressure to increase production speed and throughput while still maintaining quality. They also are making increasing demands for smart machines. The new Allen-Bradley CompactLogix 5380 controller from RockwellAutomation can help meet these demands by providingmore precision, connectivity and up to 20% more application capacity than previous CompactLogix versions. Ideal for high-speed applications with up to 20 axes of motion, the CompactLogix 5380 controller brings the benefits of the high-performance Rockwell Automation Integrated Architecture portfolio into the CompactLogix size.When combined with the newAllen-Bradley Bulletin 5069 Compact I/O system, scheduled outputs improve I/O response time to as fast as 0,2 ms. Event triggers from the I/O modules provide near-instantaneous task execution. “This new controller is particularly helpful for high- speed packaging applications where fast response times are critical for keeping production running smoothly,” said Christo Buys, Business Manager for Control Systems, Rockwell Automation, sub-Saharan Africa. “Features like scheduled outputs and event triggers, which are new to the CompactLogix family, allow engineers to design compact machines that achieve higher accuracy and precision.” In addition, a dual-configurable, 1-gigabit Ethernet port supports Device-Level-Ring (DLR) topologies or the use of multiple IP addresses.The ability to create multiple IP addresses is especially useful for manufacturers seeking to establish network separation between plant-floor and enterprise-level traffic.

This type of measurement station is much more than simply a complete system. Due to its flexible adaptability, it can serve as a solution platform for certain tasks, whereby, again task dependent, sensors with a wide range of performance capabilities are connected and evaluated. Essentially this means that the Leuze LSC 200 can also be ex- panded with sensors that perform identification tasks, such as bar code readers. Dimensions can be measured with, for example, three light curtains (length, width, height) using the optical throughbeam method. And if necessary, the width and height measurement can also be measured using scanning light section sensors or laser scan- ners. The length measurement can be optionally performed using an incremental transmitter.

Device configuration at your fingertips Comtest , local representative of Fluke Corporation, is proud to introduce its Fluke 154 HART Calibration Assistant, a standalone tablet-based com- munication tool that makes HART configuration easy. The 154 provides HART communication functionality that when combined with a Fluke 750 Series Documenting Process Calibrator or 720 Series Multifunction Process Calibrator enables the user to calibrate the full range of HART devices used in the process industry.The Android-based tablet comes configured with the FlukeHART mobile app that utilises a long-range wireless HART modem, which connects to the HART transmitter being tested or configured.This al- lows technicians to wirelessly communicate with the device up to 250 feet away eliminating the need for technicians to stand next to the device so they can work from a safer, more convenient location.The 154 provides full HART Device Description (DD) support of all HART devices and can monitor PV, SV, TV, QV, and other measured HART variables. Quarterly DD updates can be downloaded free of charge from the Fluke website for three years from the first use of the product.The calibration assistant includes a configurable connection cable that accepts either hook clips for connecting to wires or extended tooth alligator clips designed to connect to transmitter connec- tion screw heads. Its rechargeable lithium-ion battery is designed to last for several days of device testing and configuration under normal conditions. Enquiries:Tel. +27 (0)10 595 1821 or email sales@comtest.co.za
