The **M5PA-C5-R** is a high-performance, compact **Pressure Transmitter** (or pressure sensor) typically used in industrial automation, hydraulics, and pneumatic systems. It is designed to convert physical pressure into a standardized electrical signal. --- ### 1. Key Technical Specifications Below is a breakdown of the primary electronic and mechanical characteristics of the M5PA-C5-R: | Feature | Specification | | :--- | :--- | | **Sensor Type** | Piezoresistive / Strain Gauge | | **Pressure Range** | Varies by sub-model (Commonly 0-500 bar or specific custom ranges) | | **Output Signal** | 4-20 mA (Current Loop) | | **Power Supply** | 10 - 30 VDC | | **Connection Type** | M12 Connector (typically 4-pin) | | **Accuracy** | ±0.5% FS (Full Scale) | | **Housing Material** | Stainless Steel (SUS304/316L) | --- ### 2. Internal Electronic Components The device consists of several critical electronic stages to ensure signal integrity: 1. **Sensing Element:** A micro-machined silicon diaphragm or a ceramic thick-film sensor that changes resistance when physical pressure is applied. 2. **Signal Conditioning Circuit (ASIC):** An internal Integrated Circuit that amplifies the tiny millivolt signals from the sensor to a robust industrial level. 3. **Temperature Compensation:** Internal thermistors or compensation resistors that ensure the sensor remains accurate despite fluctuations in ambient temperature. 4. **EMI/RFI Filtering:** Protection circuits that prevent electrical noise from nearby motors or radio frequencies from interfering with the output signal. --- ### 3. Wiring Configuration The M5PA-C5-R typically uses a standard industrial pinout for its M12 connector: ```text Pin 1: +V (Power Supply 10-30V) Pin 2: Not Connected (or Output - in some configs) Pin 3: 0V / Ground Pin 4: Output Signal (4-20mA) ``` --- ### 4. Common Applications * **Hydraulic Systems:** Monitoring oil pressure in heavy machinery. * **Water Treatment:** Measuring pump discharge pressure. * **Pneumatics:** Controlling air pressure in factory assembly lines. * **HVAC:** Monitoring refrigerant or water loop pressures. ---
