ZSE1 is a basic vacuum switch with digital output and optional analog voltage output.  The ZSE1 monitors vacuum level down to -101 kPa.  ZSE1 can be mounted in a ZM vacuum generator system, or by metric or NPTF male threads.  Rotary trimmers adjust the switch set point and variable hysteresis if 1 output, or two set point trimmers if 2 output.  A red/green LED indicator also lights when the
