Vacuum to Ultra-Low Pressure
A Vacuum to ultra-low pressure switch is a device designed to detect and respond to very low pressures, typically in the range from vacuum (below atmospheric pressure) to ultra-low positive pressures (just above atmospheric pressure).
Monitor and control processes where maintaining precise pressure levels within this low-pressure range is critical.
Vacuum to Ultra-Low Pressure Switches
The vacuum to Ultra-Low Pressure Switch includes a highly sensitive pressure-sensing element that is capable of detecting very small changes in pressure, both in vacuum and ultra-low positive pressure ranges. These switches come with an adjustable setpoint mechanism, allowing users to define the specific pressure level (in the vacuum to ultra-low pressure range) at which the switch will activate or deactivate. This setpoint is adjusted according to the operational requirements of the specific application.
Vacuum-to-ultra-low-pressure switches are also known as "crossover switches."
These switches, designed for high sensitivity and precision, monitor low pressure levels. They are capable of detecting minute changes in pressure to ensure accurate control or alarm functions. When the pressure reaches the defined setpoint, the sensing element triggers a switching mechanism, either opening or closing electrical contacts. You can use this action to control pumps, valves, compressors, alarms, or other process equipment.
Constructed from materials that are compatible with the gases or fluids under monitoring, especially in applications that involve corrosive or reactive substances. Many models are designed to operate in harsh environments or under extreme temperature conditions.
Mechanical vacuum switches, crossover pressure switches, and similar devices use mechanical components, such as diaphragms, which move or deform in response to changes in pressure. These movements actuate the switch contacts mechanically. These switches are suitable for many standard applications that require basic control or alarm functions.
Vacuum-to-ultra-low-pressure switches are used to monitor and control the pressure in vacuum systems, such as vacuum chambers, vacuum pumps, or freeze-drying equipment. They help ensure that the desired vacuum level is achieved and maintained for various industrial, laboratory, and research applications. Crossover pressure switches are used in gas handling and distribution systems for low-pressure or vacuum gases, such as gas chromatography, semiconductor manufacturing, and chemical processing, where maintaining specific pressure levels is essential.
They are used in leak detection systems to monitor pressure drops in pipelines, tanks, or vacuum systems where a sudden drop in pressure may indicate a leak, prompting an alarm or automatic shutdown to prevent safety hazards or damage.
Vacuum-to-ultra-low-pressure switches are capable of detecting and responding to very low pressures, providing accurate monitoring and control in applications where precise pressure management is critical. They enhance safety by providing early warnings or automatic responses when pressure deviates from desired levels, preventing potential equipment damage, process disruptions, or hazardous situations.
Used in automation and control systems, they enable automated control of equipment, reducing manual intervention and improving process efficiency. Crossover pressure switches are suitable for various applications across multiple industries, including medical, laboratory, industrial, and HVAC systems, as they are designed to operate effectively in challenging conditions, such as extreme temperatures, corrosive atmospheres, or high-vibration environments.
