The D56M differential pressure switch provides high precision measurement across a wide range of low-differential pressure conditions in a package smaller than other units of comparable capability. The membrane senses changes between the “high” and “low” pressure inlets while offering excellent repeatability and high cycle life. Optional hermetically sealed contacts mean the D56M can be well suited when vapor ignition is a concern.

Typical uses include airflow control plenums.

For a similar switch with a higher resistance to shock and vibration, refer to the D16M

For qualification information, please consult the sales or engineering departments.

Features

Intended for gaseous media
Environmentally sealed with optional hermetically sealed contacts
Proven diaphragm and leaf spring technology for high cycle life

SeaHFlight is an advanced 2D/3D GIS-based command and control solution engineered for the comprehensive management of low-altitude aircraft, including helicopters, drones, and future UAMs. It provides a complete operational picture, offering full lifecycle management from initial flight planning and real-time monitoring to post-flight performance analysis. Key Capabilities: Unified Situational Awareness: Achieve superior decision-making with a dynamic 2D/3D operational map that visualizes all air assets in real-time. The system integrates crucial data layers, including weather, airspace information, and flight plans. End-to-End Mission Management: Streamline the entire operational workflow, covering everything from flight plan creation and pilot hour management to flight history recording and detailed performance evaluation. Proven Interoperability: SeaHFlight is designed for seamless data integration with key national and military agencies (Army, Police, National Fire Agency, Forest Service). This creates a unified network for complex, multi-agency public safety or defense operations. Future-Ready Platform: Built to manage not only current helicopter and drone fleets but also the next generation of Urban Air Mobility (UAM), SeaHFlight is a scalable, long-term solution for modern aviation.
