New Exhaust Noise Inspector from Bruel & Kjaer. A new all-in-one Exhaust Noise Inspector system has been introduced to the marketplace by leading global noise and vibration manufacturers Brüel & Kjær. The development of the system by the company comes in light of the Directive on Motor Vehicles 70/157/EEC "permissible sound level and exhaust system of motor vehicles" testing and the ISO working draft 5130:2002 test procedures which has been implemented by many European countries to make checks on vehicles in use. The new Exhaust Noise Inspector Type 3638 system is an easy to use sound level measurement system designed for automatic measurements of exterior exhaust noise from cars, motorbikes, lorries and mopeds under stationery conditions (engine sweep test), simultaneously with (non-contact) RPM detection. Type 3638 Primarily of use to local authorities and local police inspectors who will appreciate the ergonomics of the system, allowing measurements of vehicles in use to be performed by one single operator, as well as determining variations in the exhaust sound level which can result from: * The wear, maladjustment or modification of particular components when the defect does not appear by visual inspection; or * The partial of complete removal of devices reducing the emission of certain sound levels Exhaust Noise Inspector Type 3638 uses a unique calculator and algorithm to allow the noise level and the engine RPM to be measured with the same microphone. Non-contact measurements of the engine RPM by computation from the acoustic signal of the exhaust noise (no need to open the engine compartment), complete with instantaneous reports can be achieved. A large display with all necessary information and the additional green and red lights allow extremely simple and quick measurements, making it the easiest system on the market to operate. Uses of Type 3638: * Measurement of exterior exhaust sound level from motorbikes, cars, lorries and mopeds under stationery conditions (engine sweep test) * Non-contact measurements of engine RPM by computing the engine speed from the acoustic signal of the exhaust noise. * Allows totally non-invasive tests of vehicles - the engine bonnet or compartment cover does not need to be opened. * Acoustic detection of engine RPM for 2- and 4- stroke engines, petrol and diesel, from 1 to 12 cylinders * Suitable for use by a single operator - a dedicated computer manages the complete measurement sequence. * All-in-one suitcase. It can be carried easily on a motorcycle, for use by motorcycle police. * Intuitive setup menu for measurement configuration and engine type, via 4 keys * Remote control of the SLM, the setup, auto-range and measurements. * Simultaneous measurement and display of sound level and engine RPM * Red and green lights indicator for throttle control setup. __________________________________________________ For more information, please contact :- Bruel & Kjaer UK Ltd.
