Vacuum Monitoring
Presair’s vacuum alarm provides a simple external solution for monitoring vacuum levels in a system. A visual indicator light, with an optional audible alarm, alerts personnel when vacuum rises above or falls below a specified threshold. This system enables early detection of vacuum fluctuations to help prevent equipment issues and reduce unplanned downtime.
Tinytrol® Factory Set Vacuum Switch
Tinytrol® switches offer compact vacuum sensing with a range of connection styles for easy integration into system designs. These miniature switches provide straightforward electrical on/off control based on vacuum levels, making them suitable for space-constrained or embedded applications.
Adjustable Switches
Presair manufactures adjustable vacuum switches built to meet the performance and reliability requirements of original equipment manufacturers and instrument builders. Each switch is produced to precise standards, offering stable operation, repeatable accuracy, and cost-effective integration into a wide range of systems.
Sensitive Differential Vacuum Switch
Sensitive differential switches are designed for applications requiring low-pressure or vacuum detection with adjustable set points. These switches can be configured to sense pressure, vacuum, or the differential between two separate pressure or vacuum sources.
PCB Mount Vacuum Switches
Printed circuit board (PCB) mount vacuum switches are compact single-pole or double-pole units designed for applications where moderate vacuum accuracy is sufficient. Vacuum sensing ranges from 6 to 200 inches of water gauge (IN.W.G.). Each switch is factory set to a customer-specified actuation point, marked directly on the housing. Select models support field adjustment for flexible integration.
