Popis: In order to ensure safe and efficient operation of unit processes, foremost requirement is accurate measurement of process variables, with which quality can be monitored and controlled. Understanding the necessity of online monitoring of process temperature in tanning/dyeing process, the article is focused on wireless measurement of physical parameters involved in wet processing of hides/ skins and monitoring through digital computer for further analysis. It’s a challenging task to measure and communicate the process information from a closed rotating drum. Wireless communication is proposed because of its enhanced security, superfast operating speed, and increased mobility. The physical parameters which are predominant in tanning process are temperature, pH, conductivity etc. of the process fluid. It is necessary to carryout dyeing at 65 0C for producing raw to wet blue process. As a first attempt, wireless module for temperature measurement has been developed. The module includes signal transmitter and receiver section. In the transmitter section, the temperature which is measured by an integrated sensor is converted into frequency signal and imposed on a radio frequency signal (career signal) and get transmitted in air. On the other side, receiver section receives the radio frequency signal and converts that into electrical signals to interface with the digital computer for online monitoring. The module is able to receive and control temperature of tanning drum within a distance of 100 meters. Real time experiments on the fabricated model show interesting results for commercialization.
