Challenge:
A Mettler Toledo IND560 weighing terminal which was used in a cleanroom Class GMP B needed to be equipped with a pinch valve to automate a glass bottle filling process. Due to the environment, a solenoid operated pinch valve in stainless steel was required. The pinch valve had to communicate with the weighing terminal and close when the pre-defined set point was reached. The weighing terminal didn’t provide enough Amps to power the pinch valve, so an independent power supply was installed as well.
