The **M2PA-13-R2/Q** is a high-reliability electronic component, typically categorized as a **Pressure Sensor** (specifically a Piezo-resistive pressure sensor) often used in specialized industrial or medical applications. Below is a breakdown of its technical characteristics and specifications. --- ### 1. Technical Specifications The device is designed to convert physical pressure into a measurable electrical signal. | Feature | Description | | :--- | :--- | | **Component Type** | Piezo-resistive Pressure Sensor | | **Pressure Range** | Typically 0 to 13 PSI (subject to specific sub-variants) | | **Supply Voltage** | 5V DC (standard) | | **Output Type** | Analog (Ratiometric) | | **Accuracy Class** | High Precision / Medical Grade | | **Housing Material** | Plastic / Medical Grade Polymer | --- ### 2. Key Electronic Characteristics * **Piezo-resistive Bridge:** The core of the sensor is a Wheatstone bridge circuit. When pressure is applied to the diaphragm, the resistance of the bridge changes, creating a differential voltage. * **Temperature Compensation:** The "R2/Q" designation often refers to internal circuitry designed to stabilize the output against temperature fluctuations, ensuring a linear response. * **Signal Conditioning:** Unlike raw transducers, these units often include internal amplification to provide a millivolt or voltage output that is easier for Microcontrollers (MCUs) to read. --- ### 3. Pin Configuration and Integration Standard integration for these sensors involves three primary connections: ```cpp // Logic for reading an Analog Pressure Sensor (General Example) int sensorPin = A0; // Connected to Sensor Output float sensorValue = 0; float pressure = 0; void setup() { Serial.begin(9600); } void loop() { sensorValue = analogRead(sensorPin); // Conversion formula based on Datasheet (Vout to PSI) pressure = (sensorValue * (5.0 / 1023.0)) * CalibrationFactor; Serial.println(pressure); delay(500); } ``` --- ### 4. Applications The M2PA series is frequently found in: 1. **Medical Devices:** Blood pressure monitors and respirators. 2. **HVAC Systems:** Airflow monitoring and filter pressure drop detection. 3. **Industrial Automation:** Level sensing in small tanks and pneumatic controls.
