ZSM1, Vacuum Switch, Diaphragm Style

ZSM1 is a basic vacuum switch with 1 output.  No analog output is included.  Solid state and contact reed switch options are available,with different voltages.  The switch output turns ON when vacuum is greater that the set point.  A red LED indicator also light to correspond with the output signal.  A rotary trimmer adjusts the switch set point.  ZSM1 can be mounted in a ZM generator unit, or piped by metric or NPTF male threads.  Electrical connection is made by a 2 or 3 wire cable.  This switch is compatible with any non-corrosive, non-flammable gas.
