Abstract
Considering the need to access crucial parameters in a nuclear reactor during station blackout condition (SBO), we have proposed self-powered or process-powered sensors with wireless data transmission. Low-power electronics comprising a piezoresistive pressure sensor, amplifier, and wireless transmitter was developed for demonstration of process-powered sensor operation. The required electrical power was derived using a thermoelectric generator as an energy harvester which converts heat energy from the process to electrical energy and drives the complete electronics along with the wireless transmitter. A power management circuitry has been used for management of power fed to the electronics. The complete instrumentation has been tested in the laboratory to demonstrate the operation of process-powered sensor and wireless instrumentation. Such approach would be suitable for wireless network of self-powered/process-powered sensors and also for wearable devices by operators. An overview of this development is presented in this paper.
