Pre-Deployment Tests of Signal Conditioning Boards for Wireless Sensor Network Deployment

Abstract

Abstract

Diversity in signal measurement and transmission increases signal availability. Various well known stabilized technologies are available to use to achieve diversity in signal measurement. But to achieve transmission diversity, the wireless technology is a truly diverse mechanism of wired transmission. Wireless Sensor Network (WSN) is the practical implementation of such technology. To implement WSN for nuclear reactor signals, it requires stringent testing, qualification, verification and validation of WSN nodes and it’s Signal Conditioning Boards (SCBs). Calibration of sensor and its signal conditioning board is the basic requirement for any plant sensor or instrument. The other most important concern is that the measuring system should not load the sensor or any other existing measuring device. This loading effect may lead to unsafe conditions. With this aim to use WSN in nuclear reactors, this paper discusses about the calibration and loading effect of the SCBs designed for interfacing WSN nodes to sensors. Finally, to observe the network performance and signal behavior, a wireless sensor node has been deployed in fast breeder test reactor which transmits accurate measurements without affecting the normal functionality of wired measurements
