Presairs’ vacuum monitor is a great solution for CNC machines that utilize a vacuum table. The tables are used with flat sheets for metals, woods, papers, foils, and plastics.
Vacuum tables’ generate hold-down force, due to the difference in vacuum under the actual part. There is also atmospheric pressure that’s pushing down from above. Ultimately, keeping a flat surface when milling, drilling, carving, engraving, or cutting is crucial in order to ensure precise measurements. This is because the slightest drop or spike in vacuum can cause a bowed table surface. The automation capability of a CNC machine is an important specification as it requires no human to operate the machine. Instead, a computer independently performs the job. This avoids down time or automation issues, which saves time and reduces bottlenecks.
Welcome to the perfect notification product for monitoring vacuum! Designed for monitoring negative pressure to notify personnel as soon as loss of vacuum begins to occur or increases. These simple vacuum monitoring solutions feature a flashing light (optional audible alarm) that’s designed to grab the attention anytime vacuum is rising too high or falling too low in a system. Preventing & fixing issues before they cause significant downtime!
Presair’s vacuum alarm is available as field adjustable or factory set.
