The Platinum series is a versatile PT-DEMO PID controller from Omega and offers a fully integrated temperature control system suitable as a platform to investigate the use of closed loop (PID) and simple on/off temperature control in heating and cooling applications. The company says it is ideal for PID control theory education in universities and laboratories. The PT-DEMO is very easy to setup and use with intuitive “smart” menu flow, panel mounted USB and Ethernet connectivity, an alarm indicator, a 4 to 20 mA remote set-point potentiometer, a pushbutton digital input, and an aluminum plate allowing the user to feel the temperature response.
