Digital Pressure Switches: Unmatched Accuracy and Intelligence
A digital pressure switch is an advanced monitoring and control device that precisely converts detected pressure signals into digital data, enabling switch control based on preset thresholds. Compared to traditional mechanical switches, digital pressure switches offer significant advantages:
• Higher Accuracy: Typically achieving 0.1% or higher of full scale, far surpassing traditional switches.
• Enhanced Reliability: Lacking mechanical contacts, they experience less wear, leading to a longer service life.
• Advanced Functionality: Features include clear digital displays, programmability (for pressure thresholds and hysteresis), multiple output modes (NPN/PNP, analog), communication functions (ModBus, IO-Link), and self-diagnosis capabilities.
• Wider Adaptability: Software settings allow for easy adaptation to various applications without hardware changes.
• Higher Integration: A single digital pressure switch can replace multiple traditional components like pressure gauges and relays.
HANUMAN offers a diverse range of digital pressure switches, including the DPS-2 (universal), DPS-3 (economic), DPS-5 (anti-corrosion), DPS-6 (economic), DPS-7 (IP65), and DPS-8 (IO-LINK) series, catering to a broad spectrum of industrial environments and precision requirements. Our DPS3 models, for instance, feature precise microprocessor technology, color LCD displays, and support various measuring units and output types.

Adjustable Vacuum Pressure Switches: Precision Control for Diverse Systems
The adjustable vacuum pressure switch is a critical component in fluid control systems (both hydraulic and pneumatic), designed to provide precise control solutions for a variety of applications. Its core strength lies in its adjustability, allowing users to precisely set the operating pressure threshold to meet specific application needs, enhancing system safety and efficiency.
Vacuum pressure switches adjustable by HANUMAN are vital in areas such as automotive manufacturing, HVAC systems, and pump controls, ensuring stable system pressures and improved energy efficiency. We offer both mechanical and electronic types:
• Mechanical Vacuum Pressure Switches: Reliable and operate without auxiliary power, suitable for higher voltage and current capacities.
• Electronic Vacuum Pressure Switches: Offer flexibility, stability, and longevity, with individually adjustable parameters and the ability to generate analogous signals for advanced control.
• Pneumatic Switches: A special category actuated by air pressure, widely used for controlling pneumatic devices in demanding environments like exhaust systems and ventilation ducts.
Our adjustable vacuum pressure switches typically include terminals, contacts, a flexible diaphragm that responds to pressure changes, and an adjustment spring for setting the on/off pressure range. The DPS6 series, for example, is an economic high-precision model with a color LCD display and an M5 female thread port, providing reliable performance for your pressure control needs.
