Palm Contamination Monitor * [ TYPE : NXG_PCM738 ]
Technical Data
Palm Contamination Monitor NXG_PCM738manufactured by NUCLEONIX SYSTEMS primarily serves as a personnel monitoring system for checking the Alpha contamination of Palm of radiation workers / technicians working in Nuclear Power Plants, reactors, Radiochemical plants and other similar installations. This is wall mounted design.
It uses latest state-of- art electronic devices including SOC based on ARM cortex A5 400MHz CPU with associated peripheral devices and other discrete ICs & components. Use of these devices makes it compact & highly reliable. Powerful embedded code adds-up and enhances its performance and gives extra advantage from the angle of fault diagnostics, programmable features & measurement of count rate & data communication under, networked environment.
With power ON, initialization of SOC, peripheral devices, 5” TFT display/timers, counter etc., takes place. Start of counting is initiated by an IR source detector arrangement on detection of palm. Whenever the person place Palm on the Detector assembly Acquisition Automatically take place and shows Palm contamination levels in terms of counts or cps/cpm and Based on the Alarm set point it will Declares the CLEAN or CONTAMINATION Message. Guidance to the user during monitoring is in the form of textual messages at the end of monitoring. Additionally, hardware & fault diagnostic check will be carried out.
Palm contamination Monitor NXG_738 indicates Count rate digitally on TFT display. There are visual annunciator windows, GREEN & RED for CLEAN & CONTAMINATION conditions respectively, shown on TFT display. The RED window screen flashes, when the count rate alarm occurs and in CLEAN condition the GREEN window glows.
