optical turbidity measuring system
KROHNE’s OPTISYS TUR 1060 optical turbidity measuring system is suitable for quality monitoring or filter monitoring in drinking water, or in cooling water circuits or demineralisation processes. The new analytical system employs 90°
scattered light technology and is compliant to US EPA 180.1 and EN ISO 7027. It comes with 4…20mA and Modbus RS485 communication and features improved usability, fast measuring response time, simple and cost-efficient calibration, data logging and low maintenance requirements. Although OPTISYS TUR 1060 shares components with its predecessor
OPTISYS TUR 1050 and can be retrofitted, the system has been completely redesigned: it provides improved usability due to cursor keys and simple start-up and operation without special knowledge. For flexible use, the measuring ranges can be adapted according to the application. It can be calibrated with reusable calibration cuvettes in less than five minutes, without dangerous formazine contact. The new system has an integrated data logger for storing measurement
readings and the last four calibrations up to one year. Calibration data and logged data can both be downloaded via the USB interface.

circular connectors for harsh environments
Phoenix Contact is expanding its range of IP-protected PRC series circular connectors. Inverted cable connectors and
couplings are the solution for reliable cable-to-cable connections in building, industrial and outdoor applications. Modular basic housings and contact inserts also make angled conductor outlets possible for the first time. The housings are available in
different versions for 0°, 45° and 90° exit angles and can be equipped with contact inserts for socket or pin contacts depending on the application. The inverted connectors and contact inserts are available in three- or five-position versions and offer a high degree of protection up to IP69K. The circular connectors are
designed for currents up to 35 A and voltages up to 690 V AC (III/2), and are up to 75 per cent more compact than conventional industrial connectors. Thanks to the weatherproof materials, they are also suitable for indoor and outdoor use.

large aperture current transducer
Danisense has introduced the DM1200, a high-accuracy current transducer capable of measuring signals up to 1,200Arms and 1,500A DC. Specifically targeting the eV and heV markets which require higher power converters that can be rapidly-charged, the DM1200 also features a large 45mm diameter aperture which makes testing easier and more cost-effective as frequent installation and replacement of the system under test can be performed without the need to remove the primary cable connector. Like all Danisense current sensors, the DM1200 is based on a closed loop system, powered by a flux gate as the magnetic field detector. Thiszero-flux technology enables the DM1200 to feature linearity of <1ppm with a low offset of 12ppm and low amplitude and phase shifts. These parameters are critical for accurate measurement of the efficiency of the converter, as they cause measurement errors. The DM1200 also features a high bandwidth of up to 300kHz, to match
increased switching speeds, especially of SiC and GaN devices. In order to shield against EMC disturbances caused by these high frequency signals, the DM1200 incorporates a metal body as a shield.

new vision systemfor multi-camera applications
Teledyne DALSA has introduced a new compact, low-cost vision system for multi-camera applications. The GEVA 400
system offers cost savings for multi- camera vision applications, such as final inspection of large assemblies. The four Power-over-Ethernet (PoE) compliant Gigabit camera ports are compatible with a wide range of cameras, including Teledyne DALSA’s industry leading Genie Nano GigE. Adding cameras is easy with commercially available network technologies, enabling larger configurations at much lowersystem costs. The GEVA 400 features the latest Intel quad-core ATOM™ architecture, and offers low power consumption and solid performance for a wide range of machine vision applications. In addition, the system can be easily expanded with an optional PL-USB companion module that offers I/O expansion and easy integration for up to four GigE cameras. In addition to the four PoE camera ports, the GEVA 400 includes Ethernet
and serial ports for communicating with 3rd party devices, four USB ports for setup and run-time control, and a factory enterprise, dedicated display. Vision solutions on the GEVA 400 are setup using our integrated iNspect or Sherlock software applications. iNspect software is easy to use and requires little or no prior vision experience, while Sherlock offers greater flexibility to tackle more challenging inspection tasks. Both software packages offer a wide selection of tools and capabilities for applications requiring positioning, identification, verification, measurement, and flaw detection.
