ISE1 is a basic pressure switch with digital output and optional analog voltage output.  The ISE1 monitors the pressure of any non-corrosive, non-flammable gas.  Low and high pressure ranges are offered, as well as metric or NPTF male thread connections.  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
