New line of sensors for use in hazardous areas

ATEX approved equipment and devices are commonly used in hazardous working conditions. They need to be extra strong and durable to withstand the elements that they will be exposed to. ifm has designed and developed its newest line in ATEX protection. ifm ’s type IND inductive sensors are in- trinsically safe and consist of two inductive sensors in a potted and robust housing with IP 67 protection rating. They are equipped with connection for solenoids.Two sensors are built-in: one sensor provides a signal when the valve is open, the other when it is closed.

The solenoid connection is optionally a standardised M20 x 1 connector or an M12 connection.The terminal chamber is easy to open and close. Since the terminal block can be removed, no newwiring is required if the sensor is replaced.The units are approved to ATEX categories 1D/1G and 2G. The IND sensors provide easy access to the terminal chamber and feature a remov- able terminal block for easy wiring and a robust and resistant housing. They have a permanently legible lasered type label and fit directly on valve actuators. Enquiries:Tel. 012 450 0370 or email info.za@ifm.com

New micro-controller condition monitoring system

Instrotech , distributor and manufacturer of a range of process control instrumentation and specialised systems, has announced the launch of UK-based Monitran’s MTN/5000; a cost-effective

based design, for example temperature, pressure, voltage/current/ power. The MTN/5000 is housed in an extruded aluminium enclosure and features a 9 cmTFT touch screen with a high performance ARM Cortex-M3 processor. It has an easy-to-navigate menu that enables users to set data sampling periods up to 1million/second, ranges and accuracy levels plus vibration threshold (alarm) levels on a channel- by-channel basis or across all 12 channels. In addition, the system has 12 digital I/O channels that can be used for multiple alarms or a communication channel for integration with other systems. As an optional extra, the system can be fitted with ModbusTCP/IP, for networking purposes or to enable multiple MTN/5000s to operate together within a larger monitoring or control system. The MTN/5000 system is made to order and, in addition to specify- ing how many input channels the MTN/5000 should have, the user can request front panel customisation, such as asset numbering. The system requires an input voltage of 24 Vdc and the enclosure dimensions, including glands are 372 x 250 x 200 mm. Enquiries: Pieter Deysel.Tel: 010 595 1831 or email sales@instrotech.co.za

Multi-functional Vision Sensor Automation Controls . The iVu Plus Gen2 line, developed by Banner Engineering, includes integral and remote screen models

A new generation of vision and barcode sensors offering multiple tools and resolu- tion options has been introduced by RET

industries.They offer a coarse mode resolu- tion setting that can provide significantly faster read rates, especially for 2D barcodes. The sensors can store and control up to 30 inspections for fast product changeover. The rugged IP67 rated housing allows use in hostile environments. Remote displays are available in both machine mountable and hand-held configurations. An intuitive touch-screen user interface allows the user to configure, monitor and modify inspec- tions without an external PC. EtherNet/IP and Modbus/TCP connectivity simplifies communications with many PLCs and HMIs. Enquiries:Tel. 011 453 2468. Visit www.retautomation.com

for use in a wide range of inspection, machine vision and quality control applications.The vision sensors with built-in illumination are designed to solve applications that would typi- cally require multiple photoelectric or proximity sensors.They now include a full resolution option to detect small features, as well as the capability to use multiple sensor tools in the same inspection. Bar code readers validate twelve 1D and 2D barcode formats to support advanced traceability in all
