Key Technical Specifications Below are the primary electronic and physical parameters for this specific model: | Parameter | Specification | | :--- | :--- | | **Pressure Type** | Gauge Pressure | | **Rated Pressure Range** | 0 to 5 MPa (Approx. 725 PSI) | | **Output Type** | Analog Voltage (1 - 5V DC) | | **Switch Output** | 2 NPN Open Collector Outputs | | **Supply Voltage** | 12 to 24 V DC (±10%) | | **Current Consumption** | 35 mA maximum | | **Accuracy** | ±0.5% F.S. (Full Scale) | | **Connection Type** | M12 Connector (4-pin) | --- ### 2. Electronic Components & Features The device integrates several core electronic stages to convert physical pressure into a usable signal: #### A. Sensing Element * **Double Diaphragm Structure:** It utilizes a stainless steel diaphragm (SUS 316L) with an internal oil-filled cavity. The sensor itself is a **diffused-type silicon piezo-resistive bridge**, which changes resistance when pressure is applied. #### B. Signal Conditioning (ASIC) * **Amplification:** The low-level millivolt signal from the silicon sensor is amplified to a standard **1–5V analog signal**. * **Temperature Compensation:** Internal circuitry offsets errors caused by thermal expansion, ensuring stability between -10°C and 60°C. #### C. Switching Logic * **NPN Open Collector:** The "P" in the model name indicates the output configuration. It features two independent switch outputs that act as electronic switches, grounding the load when the pressure setpoint is reached. --- ### 3. Wiring Configuration The device typically uses an M12 4-pin connector. The standard electronic pinout is as follows: | Pin Number | Wire Color | Function | | :--- | :--- | :--- | | **1** | Brown | Power (12-24V DC) | | **2** | White | Switch Output 2 | | **3** | Blue | Common (0V / Ground) | | **4** | Black | Switch Output 1 / Analog Output | --- ### 4.
