The **PS86-104P-H-R2** is a high-precision, industrial-grade pressure sensor manufactured by Nidec Components (formerly Copal Electronics). It is specifically designed for environments requiring high reliability and compatibility with corrosive gases or liquids. --- ### 1. Technical Specifications The following table outlines the primary electrical and mechanical characteristics of the device: | Parameter | Specification | | :--- | :--- | | **Pressure Type** | Gauge Pressure (Liquid or Gas) | | **Rated Pressure Range** | 0 to 1,000 kPa (approx. 10 bar / 145 psi) | | **Output Type** | Analog Voltage (typically 1 to 5V DC) | | **Supply Voltage** | 12 to 24V DC (±10%) | | **Pressure Port/Fitting** | R2 (R 1/4" Threaded) | | **Accuracy** | ±0.5% F.S. (Full Scale) | | **Operating Temp.** | -20°C to +85°C | --- ### 2. Key Features and Components The "PS86" series utilizes specific technologies to ensure durability: * **Stainless Steel Diaphragm:** The sensing element uses a SUS316L stainless steel diaphragm. This makes it highly resistant to corrosion, allowing it to measure "harsh" fluids that would damage standard silicon sensors. * **Oil-Filled Cell:** The internal sensor chip is isolated by silicone oil, which transfers pressure from the diaphragm to the silicon sensing element. * **Built-in Amplifier:** It features an internal temperature compensation circuit and an amplifier, providing a linearized analog output ready for PLC or microcontroller integration. --- ### 3. Model Name Breakdown Understanding the suffix codes helps identify the exact configuration: | Code Segment | Meaning | | :--- | :--- | | **PS86** | Series Name (Standard Industrial Pressure Sensor) | | **104** | Pressure Range Code (104 = $10 \times 10^4$ Pa = 1,000 kPa) | | **P** | Pressure Type (P = Positive/Gauge Pressure) | | **H** | Output Specification (H = 1 to 5V Analog Output) | | **R2** | Fitting Size (R2 = R 1/4 Thread) | --- ### 4. Connection Interface Typically, these sensors use a 3-wire or 4-wire system: * **Red:** Power Supply (Vcc) * **White:** Output Signal (Vout) * **Black:** Common Ground (GND) * **Shield:** Frame Ground
