INNOVATIVE INSTRUMENTATION SECTION

Unconventional Instrumentation Devices

            There is a need for continuous evolution of more reliable means of instrumentation and control as radioactive plants, facilities and laboratories rely on extensive network of instruments involving a variety of sensors. One always looks for simple, more flexible and more dependable devices with improved performance. An important objective of the research programme at the Innovative Instrumentation Section (IIS) [erstwhile Ultra Sensitive Devices Techniques Section (USDTS)] is to realise simple yet powerful devices for sensing, and develop instrumentation using them with reduced electrical, electronic and mechanical hardware.

            Ab initio research brought about a qualitative change in sensing and instrumentation in diverse fields of measurement through conceptualization of a generic approach that permitted easy realisation of devices entirely in digital domain. The developments are characterised by the following features:

                   -Simplicity, flexibility and ease of realisation
                    -High performance (high speed, high precision, high sensitivity)
                    -Easy signal transmission (wired or wireless) and processing
                    -Inexpensive

            The unconventional approaches in the section ushered in simplicity and flexibility in high performance sensor design at low cost, ease of primary signal generation directly as trains of digital pulses with nominal power supply needs, effortless wired or wireless transmission to data acquisition terminals with ready adaptability with simple digital systems for data processing and presentation. These are indeed desirable features for instrumentation programmes anywhere.

          Extent of use in different off-line or real time measurement / monitoring / surveillance applications, to which these sensing devices have already been deployed through creation of appropriate hardware and software for complete instrumentation, is given below in Table 1. By no means are these the only applications that are possible. One can use the sensors in many more areas as well.
