Pressure Switch Monitors Line PressureMonitoring airline pressure has never been easier with Presair’s Pressure Monitor. By pairing a pressure switch with a quick connect coupling allows for effortless setup. A magnetic stack light and/or alarm connected to the switch alerts personnel as soon as the airline drops below your specified PSI. A protective switch boot keeps connections safe and damage free. It’s valuable to know the moment your air system loses pressure. This solution will save you money and time.

In this application, we used Presairs’ adjustable pressure switch. Its broad range of setting pressures and high proof pressure rating provided the ideal switch for monitoring airline pressure. A form-fitting switch boot, made from soft PVC, provides a layer of protection for the wiring terminals of the switch.

The stack light in this application comes in red and green color. A two tiered stack light can be used, with a green state and a red state. It can also be equipped with an alarm. Its 110V connection allows for bright luminosity and loud sound to alert anyone nearby of the drop in airline pressure. It also features a magnetic base, so it can be mounted to a convenient location. It’s best to know as soon as possible when air pressure is lost. It will help catch an issue faster before it becomes a larger issue.

These simple pressure monitoring solutions feature a flashing light (optional audible alarm) that’s designed to grab the attention anytime pressure is rising too high or falling too low in a system.  Preventing & fixing issues before they cause significant downtime!

Presair’s pressure alarm is available as field adjustable or factory set.

Built with a field adjustable pressure switch, this model can be set directly by the user with a range of 1-125 PSI. It can monitor pressure rise or fall at a the user’s set point using the stack light to notify light only or light & audible alarm.
