Compact multi-touch panel PCs

capability with excellent thermodynamics. These processors enable an exceptionally compact device design and are available with 1, 2 or 4 cores, allowing best-possible adaptation to a diverse range of application requirements.This is supported by a wide range of display options, including seven multi-touchTFT displays in sizes between 12-inch and 24-inches, with 4:3, 5:4, or 19:9 (widescreen) formats. The CP37xx can be used in ambient temperatures up to 45 °C. Heat dissipation is provided by exterior heat sink fins, aided by fans to provide uniform temperature distribution inside the housing.

Beckhoff has introduced the new CP37xx series Panel PCs with multi-touch function- ality and advanced Intel Atom processors for high PC-based performance in a com- pact housing. These devices are designed for mounting-arm installation and feature full IP 65 protection. With a large number of display sizes and processor options, the CP37xx series offers high scalability to solve a wide range of automation chal- lenges. The Panel PCs feature robust aluminium housings and are equipped with Intel Atom processors, known for their high comput- ing power and excellent on-board graphics

The Panel PC can be extended flexibly, for example with PCI modules and/or a third Ethernet port. It also features an integrated rotatable, tilting mounting arm adapter for a 48 mm diameter mounting-arm tube. Enquiries: Email KMCPherson@beckhoff.com

NEW 3-Phase energy and power disturbance analysers The MAVOWATT 230, 240, 270 offer the best value in a power qual- ity, demand, and energy analyser from GOSSEN METRAWATT, or any other power quality ana-

lyser manufacturer. No other product comes close to matching the benefits and features provided by the MAVOWATT 2XX. The MAVOWATT 2XX merges the state-of-the-art power monitoring capabilities, with ‘best in class’ communication capabilities to provide a revolutionary monitoring experience. Available from Timecount , the MAVOWATT 2XX enables users to review data and change settings remotely from virtually any smart- phone, tablet mobile device, as well as with traditional PC and MAC laptops and desktops. Just hook up the instru- ment, close the cabinets to the ‘safe’ environment, and use either theVNC interface or our HDPQApple or Android Apps via Ethernet for remote control from anywhere with connectivity to the instrument. Enquiries:Tel. 011 882 3105 or email sales@timecount.co.za Instrotech , local distributor of process control instrumen- tation and specialised systems, manufactures a 4 digit (-1999 to 9999) LED universal temperature indicator for applications where temperature needs to be displayed and controlled. The model 4003 is designed for highly accurate measurement and display (in ºC, ºF or K) of temperature thermocouples, selectable from the front push buttons, of Type J, K, N, R, S,T,W5 and fromRTDs such as PT100. Ni100 RTD is available as an option as well as other thermocouple types. The thermocouple and RTD signals are accurately linearised by the internal micro-controller. Options include programmable analogue output, single, dual, three and four alarms, peak hold, and RS232/485 output. Selected op- tions now feature ‘Plug & Play’ technology, allowing option boards to be ordered separately and field fitted as required.
