Vacuum switches - Electronic

 

Fully electronic supervision of vacuum systems in order to minimize cycle times and/or to maximize the process safety. Can be used as a measuring or switching element. Suitable for control loops.

  • Maximum flexibility, since the switching point and hysteresis can be programmed as desired
  • Versatility of application by one analog and one digital output
  • Highest level of accuracy and maximum durability as a result of the fully electronic design
  • Easy operation using 3 keys and dual-coloured LEDs

Vacuum switches - Electronic, with display

 

Fully electronic supervision of vacuum systems in order to minimize cycle times and/or to maximize the process safety. Can be used as a switching element with two isolated digital outputs. Suitable for control loops.

  • Maximum flexibility, since the switching points and hysteresis can be programmed as desired
  • Two limit values retrievable using two isolated switching outputs
  • Highest level of accuracy and maximum durability as a result of the fully electronic design
  • Easy operation using 3 keys and LCD display
  • Supplementary indication using dual-colored LEDs
  • With degree of vacuum display via LCD
