BUSINESS DATA LOGGING Bosch logger


Bosch Motorsport unveiled two new data loggers at the PMW show in Cologne, Germany – the DDU 7 Sport Line dash logger and C 50 data logger. The dash logger is based on the same platform as the company’s DDU 8 Performance Line model and integrates a fully programmable colour dashboard with a data logging system. Features include a 5.7in, full colour, trans-reflective TFT display, 10 multi-colour LEDs, fully configurable display pages and shift / warning lights. It allows for synchronised acquisition and visualisation of engine data from the ECU and chassis data from six analogue and four digital wheel speed input channels. Additional input devices can


HARDWARE XRP protective sleeving


Racecar plumbing specialist, XRP, has produced a new range of heat protective sleeving to protect and insulate engine hoses, brake lines and wiring in high ambient heat areas. Fyre Jacket features a smooth,


extruded, silver silicone coating over a thick, open-knit glassfibre sleeve, offering excellent long-term insulation and burn-


through protection when fitted loosely over hoses or wires. Also available is the lightweight Fyre Foil II and ultra lightweight Fyre Foil Lite, both manufactured from Dual Mirror aluminised glass fibre fabric with a laminated Mylar outer film for protection. Sizes are available to suit -3


through to -20 hosing, plus some larger sizes for duct protection. See www.xrp.com for more information


SENSORS Gill ultrasonic sensor


be connected via Ethernet and two CAN buses, with data from the 2GB internal flash memory downloadable via a high speed Ethernet connection. The DDU 7 has a lightweight, synthetic housing and offers recording on a removable USB flash drive as an optional upgrade. The C 50 Sport Line data


logging system offers all the features of the DDU 7, but without the visual display. See www.bosch-motorsport. com for more information


Gill Sensors has developed a new ultrasonic fuel flow sensor, designed specifically for use in racing applications. Lightweight, compact, robust and designed to withstand the extreme levels of vibration experienced in this environment, the new sensor utilises proven ultrasonic measurement technology to detect bi-directional fuel flow rate to within 0.25 per cent accuracy in real time, marking a major step forward from impellor flow devices often used in racing. The ultrasonic technology has a number of major advantages over impellor flow sensors, the most significant of which is the removal of mechanical parts from the flow path. This ensures minimal pressure drop across the sensor, providing true flow rate data with little impact on the flow itself. The removal of mechanical moving parts and bearings also eliminates


mechanical dampening and allows much higher temporal resolution and accuracy for the measurement of high frequency pulsating flows, allowing even the pulses of fuel injectors in low rpm ranges to be identified. The ultrasonic fuel flow sensor has been designed for use with all race fuels, including aggressive ethanol blends, and is capable of accurately recording flow rate from 0.5-3000ml/min. The sensor also features


a newly-developed electronic platform, which integrates the latest FPGA technology, capable of measuring flow rate up to 4000 times a second. In addition to a digital output, a 0-5V analogue output is provided across the calibrated flow range. See www.gillsensors.co.uk for more information


HARDWARE Arnold express fasteners


German company, Arnold Umformtechnik, has launched ‘Fastener Express’ – a bespoke fastener production service. The concept offers designers the chance to develop complex fasteners as prototypes and then to take their ideas straight into manufacture. A dedicated rapid


prototyping team eliminates the time lost through administrative processes during a production schedule, while the direct acceptance process removes the request delay times typical found when planning production runs.

Upon receipt of an order, a technical evaluation of factors such as materials and testing the mechanical properties of a joint is automatically triggered. Additional time savings


arise from the simultaneous transformation of 3D CAD data into physical products. Blanks are then sent directly to machining, where they are turned into finished parts. A wide variety of finishing options are also available in house, including heat treatment and electroplating. See www.arnold- uk.com for more information
