Profile: McLaren Electronic Systems Ltd manufactures & supplies electronics, software and components for the motorsport, automotive and aerospace industries. The infra-red sensor measures temperature at a distance without contacting the target. The integrated infra-red module senses the thermal radiation emitted by objects and converts this to an analogue voltage. It is resistant to oil, standard fuel, hydraulic fluid and water. Accelerometers are available to measure up to three axes in a single, robust package. The sensing element is a micro-machined MEMS device. An internal amplifier provides an output between 0 and 5 volts. The unit contains a ±35g sensing element which is scaled to ±20g. This element can be replaced with a ±10g or ±50g sensing element and scaled to suit the G range of interest and application.
