The **PA-830-352A-R2** is a high-precision pressure transducer manufactured by Nidec Components (formerly Copal Electronics). It is specifically designed for industrial applications requiring stability and resistance to corrosive environments. ### 1. General Specifications The following table summarizes the primary electrical and mechanical characteristics of the device: | Feature | Specification | | :--- | :--- | | **Pressure Type** | Absolute Pressure | | **Rated Pressure Range** | 0 to 350 kPa (approx. 3.5 bar / 50 psi) | | **Output Type** | Analog Voltage | | **Output Voltage Range** | 1 to 5 VDC | | **Supply Voltage** | 12 to 24 VDC (± 10%) | | **Current Consumption** | ≤ 10 mA | | **Accuracy** | ± 0.5% F.S. (Full Scale) | --- ### 2. Internal Electronic Components The device utilizes several key electronic stages to convert physical pressure into a usable electrical signal: * **Diffused Silicon Sensor:** The core is a piezoresistive silicon chip. When pressure is applied, the resistance changes proportionally. This chip is isolated by a stainless steel diaphragm to protect it from the media. * **Signal Conditioning Circuit:** * **Amplifier:** Since the raw bridge output from the silicon sensor is in millivolts, an internal Op-Amp scales the signal to the standard 1–5V range. * **Temperature Compensation:** Internal thermistors or compensation resistors ensure the output remains stable despite fluctuations in ambient temperature. * **Protection Circuitry:** Includes reverse polarity protection and noise filtering to ensure the sensor survives industrial electrical environments. --- ### 3. Connection Interface The "R2" suffix typically denotes the specific cable or connector configuration. * **Red Wire:** Power Supply (+) * **White Wire:** Output Signal (+) * **Black Wire/Shield:** Common Ground (COM) ### 4. Key Applications * **Industrial Machinery:** Monitoring hydraulic or pneumatic lines. * **Chemical Processing:** Due to the SUS316L stainless steel housing, it is resistant to many corrosive gases and liquids. * **Medical Equipment:** High-precision air or liquid pressure monitoring. ---
