Abstract

A prototype DSP-based conditioning electronics module for a range of position transducers was produced by Penny and Giles Controls Ltd, United Kingdom, in 12 months with a budget of 45KECU. The company has 320 employees, with four engineers involved in electronics design.

The company designs and manufactures high quality position measurement and control products for applications within the aerospace and industrial markets. Products include precision rotary and linear potentiometers, non-contacting linear and rotary displacement transducers, tilt sensors, optical encoders, joystick controllers together with associated analogue signal conditioning electronics.

The new design offers higher performance and simpler power requirements compared to the existing completely analogue product. It also provides an optional digital position output, which is increasingly becoming a requirement for use with control systems. The cost of the new product is currently similar to the existing product, however a further design iteration to remove a supporting PIC microcontroller (used for sinewave generation) is intended before full production. The new product will strengthen our position in existing markets, and will also enable us to target new markets such as vehicle borne equipment.

The experiment will be of interest to any companies involved in sensor/transducer design, or in analogue control electronics. It emphasises the importance of working closely with marketing when defining the product, and in periodically reviewing the specification during the development period. It also shows how the company was able to resolve a particularly troublesome technical problem relating to the DSP chip interfacing, by seeking a company with direct experience of the particular DSP chip used.

The payback period is expected to be 3 months, following the start of full production sales. The return on investment (total profit/development cost), based on total sales up to the end of year 2000, is expected to be 1400%.
