The **M2AS1-A213-R2** is a specific technical part number, typically associated with industrial automation components, specifically **pressure switches** or **sensors** often manufactured by brands like **AZBIL (formerly Yamatake)**. Below is a breakdown of the electronic and mechanical characteristics typically associated with this series of devices. --- ### 1. Component Overview This device is generally classified as an **Electronic Pressure Switch**. It is designed to monitor fluid or gas pressure and trigger an electrical signal (output) when a specific threshold is met. ### 2. Technical Specifications | Feature | Typical Specification | | :--- | :--- | | **Part Series** | M2AS (Micro-Differential Pressure Switch) | | **Sensing Element** | Diaphragm-based electronic sensor | | **Output Type** | Relay Contact or Transistor (depending on configuration) | | **Voltage Rating** | Usually 12-24V DC or standard AC control voltages | | **Enclosure Rating** | IP65 or equivalent (Dust/Water resistant) | | **Connection Type** | R-type (Threaded) or specific flange mounts | --- ### 3. Electronic Architecture The internal electronic parts of an M2AS series switch usually include: 1. **Pressure Transducer:** Converts physical pressure into a low-level electrical signal (Wheatstone bridge or capacitive). 2. **Signal Conditioning Circuit:** An Op-Amp (Operational Amplifier) stage that filters and amplifies the transducer signal to prevent false triggering from noise. 3. **Comparator/Microcontroller:** Compares the processed signal against the user-defined "Set Point." 4. **Output Switch:** * **Mechanical Relay:** Provides "Dry Contacts" (NO/NC) for high-load switching. * **Solid State (NPN/PNP):** Used for high-speed switching into PLCs. --- ### 4. Code Breakdown (Nomenclature) While exact codes vary by manufacturer, the suffix **A213-R2** usually defines: * **A2:** Indicates the pressure range (e.g., 0 to 2 kPa). * **13:** Refers to the output type (Single or Dual set points). * **R2:** Defines the physical port size or the electrical connector type (often a specific thread size like G1/4 or R1/4). ### 5. Common Applications * **HVAC Systems:** Monitoring filter clogging by measuring differential pressure. * **Clean Rooms:** Ensuring positive pressure to keep contaminants out. * **Pneumatics:** Verifying air pressure in industrial assembly lines. ---
