Adjustable Pressure Monitor
Light with Alarm Kit

This pressure alarm kit is the perfect solution for monitoring pressure and being alerted. A bright light and loud audio alarm will notify you the moment pressure falls too far or rises too high. It will grab the attention of qualified personnel. Prevent and fix issues before they cause you significant downtime!

The pressure switch is field adjustable using the hex head set screw at the center of the pressure switch (can be set anywhere between the range you select). All switches are 100% tested at high and low settings and at proof pressure tested.

Optional magnets can be added to the base of the stack light. This allows you to place the stack light anywhere a metal surface is present. A few examples of where to place it would be up high on a metal wall or on a metal machine.

Pressure Monitor Kit includes:

  • • Adjustable pressure switch (range: 1-125 PSI)
  • • Differential Pressure ±10 psi
  • • Protective switch boot
  • • Stack light with audio alarm function
  • • Magnets on light base (optional)

The adjustable pressure switch is UL & CUL rated for 100,000 cycles at 5 Amps @ 240VAC.

  1. David Landis (verified owner)

    This is an amazing pressure alarm. It is compact and with the optional magnets I can move it anywhere I want. Plenty loud enough to be heard in a noisy plant. I will purchase more as spares and some for more places in the plant.They are very easy to adjust. I highly recommend these if you are considering a low cost audible alarm for your plant air or other inert gasses.

  2. Kenny Moyer (verified owner)

    This is a good visual and audible low cost way to monitor at my plant air pressure . I got 2 and will get at least 3 more . Easy to install and adjust

  3. Chris Harmon (verified owner)

    This product solved the problem I was having with our CNC. We now know when the air pressure is low. It pays for its self in saved tooling cost.

    I bought this to install on an oxygen line in a veterinary clinic. We needed something to indicate a loss of pressure, and this was perfect. The price is great and the quality is very high too. Would recommend to anyone.
