pH-value control in a sugar factory

Sugar manufacture is a process requiring tight control of the pH-value in m any stages. Ideally, measurement and control of the pH value should occur a t process temperatures and pressures with a minimum dead time. This is acco mplished by lacing the pH sensor directly into the main process line. This paper addresses these issues by discussing the pH sensor technology. It als o includes installation and maintenance guidelines and suggestions on calib ration, measurement validation and troubleshooting.
