System monitors turbocbarger speed. Micro-Epsilon's eddy NCDT Series DZ13O is designed for revolution counting and incorporates a compact design controller with analogue and digital analogue output, plus a miniature sensor with a diameter of 3mm. The sensor system is being used by turbocharger manufacturers to monitor the speed of their units up to 400,000rpm. End user automotive companies such as Ford, Land Rover, Bentley and Jaguar are also using the sensors to map engine performance in test cells. The sensor works on the eddy current measurement principal. A coil is potted in a sensor case and is energised by a high frequency alternating current. The electromagnetic field from the coil generates eddy currents in the turbocharger blade. Every blade generates a pulse and the controller identifies the speed by considering the number of blades. The system is optimised for mobile and stationary use in test and R&D operations. Adjustment and set up of the sensor is via a status LED. The 6m length of the sensor cable and the different signal outputs are said to guarantee flexibility for the application. The eddy current principle is said to be immune to oil, dirt, dust, moisture and interference fields and is therefore suitable for use in harsh industrial environments. ________________________________________________________ For further information, please contact:- Chris Jones Micro-Epsilon UK Ltd.
